Abstract
Abstract An operating mechanism for controlling the movement of a valve element. The mechanism includes support means movable in response to the rotation of a driving shaft means. The support means has a plurality of adjusting means connected thereto and arranged along a predetermined path thereon. A continuous deformable channel having a pair of opposed cam surfaces is defined by means connected to the adjusting means. A follower means is positioned in the channel so as to follow each of the cam surfaces. The cam surfaces translate the follower means in converse directions in response to the rotation of the driving shaft means. Connecting means join the follower means with a valve element that moves between an open and a closed position in response to the translation of the follower means.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
137 words
A valve operating mechanism for controlling a valve element movable between an opened and a closed position comprising: a. rotatable driving shaft means; b. support means movable in response to rotation of said driving shaft means; c. adjusting means arranged along a predetermined path on said support means; d. means connected to said adjusting means to define a continuous deformable channel having a pair of opposed cam surfaces; e. follower means positioned in said channel and adapted to follow each of said cam surfaces so that said cam surfaces translate said follower means in converse directions in response to rotation of said driving shaft means; and f. connecting means joining said follower means to said valve element to move said valve element between said open and closed positions in response to said translation of said follower means.
Claim 2
Dependent Claim
137 words
A valve operating mechanism for controlling a valve element movable between an opened and a closed position comprising: a. rotatable driving shaft means; b. support means movable in response to rotation of said driving shaft means; c. adjusting means arranged along a predetermined path on said support means; d. means connected to said adjusting means to define a continuous deformable channel having a pair of opposed cam surfaces; e. follower means positioned in said channel and adapted to follow each of said cam surfaces so that said cam surfaces translate said follower means in converse directions in response to rotation of said driving shaft means; and f. connecting means joining said follower means to said valve element to move said valve element between said open and closed positions in response to said translation of said follower means.
Claim 3
Dependent Claim
29 words
A valve operating mechanism in accordance with claim 1 wherein said deformable channel is formed by a plurality of individually adjustable open channel segments aligned along said predetermined path.
Claim 4
Dependent Claim
25 words
A valve operating mechanism in accordance with claim 2 wherein bridging means are disposed on each of said cam surfaces between said open channel segments.
Claim 5
Dependent Claim
16 words
A valve operating mechanism in accordance with claim 3 wherein said bridging means comprises flexible springs.
Claim 6
Dependent Claim
25 words
A valve operating mechanism in accordance with claim 2 wherein said adjusting means comprises a plurality of adjusting screws individually attached to said channel segments.
Claim 7
Dependent Claim
37 words
A valve operating mechanism in accordance with claim 4 wherein a rotational movement of one of said adjusting screws causes a translating movement of one of said channel segments and thereby adjusts the contour of the channel.
Claim 8
Dependent Claim
151 words
A valve operating mechanism for controlling movement of a valve element between an opened and a closed position comprising: a. a rotatable driving shaft; b. support means affixed to said driving shaft so as to rotate therewith; c. a plurality of adjusting screws arranged along a circular path along said support means; d. a plurality of C-shaped channel segments affixed to said adjusting screws and defining opposed cam surfaces which cooperate to form a deformable channel disposed in a circular arc about said driving shaft; e. a roller positioned in said channel and adapted to follow each of said cam surfaces so that said cam surfaces translate said roller in converse directions in response to rotation of said driving shaft; and f. a driven shaft joining said roller to said valve element to move said valve element between said opened and closed positions in response to said translation of said roller.
Claim 9
Dependent Claim
151 words
A valve operating mechanism for controlling movement of a valve element between an opened and a closed position comprising: a. a rotatable driving shaft; b. support means affixed to said driving shaft so as to rotate therewith; c. a plurality of adjusting screws arranged along a circular path along said support means; d. a plurality of C-shaped channel segments affixed to said adjusting screws and defining opposed cam surfaces which cooperate to form a deformable channel disposed in a circular arc about said driving shaft; e. a roller positioned in said channel and adapted to follow each of said cam surfaces so that said cam surfaces translate said roller in converse directions in response to rotation of said driving shaft; and f. a driven shaft joining said roller to said valve element to move said valve element between said opened and closed positions in response to said translation of said roller.
Claim 10
Dependent Claim
34 words
A valve operating mechanism in accordance with claim 7 wherein flexible springs are disposed on each of said cam surfaces so that said roller can bridge from one of said C-shaped segments to another.
Claim 11
Dependent Claim
18 words
A valve operating mechanism in accordance with claim 7 wherein said screws are threaded through said support means.
Claim 12
Dependent Claim
39 words
A valve operating mechanism in accordance with claim 7 wherein a rotational movement of one of said adjusting screws causes a translating movement of one of said C-shaped segments, and thereby selectively varies the contour of said cam surfaces.
Claim 13
Dependent Claim
110 words
A valve operating mechanism for controlling movement of a valve body comprising: shaft means for rotating in response to an input setting; camming means for variably programming movement of said valve body, said camming means being affixed to said shaft means for rotation therewith and having a channel, said camming means having segments for forming said channel; bridging means disposed in said channel for forming continuous, opposing camming surfaces in said channel, said camming surfaces having a predetermined contour; and follower means for engaging said bridging means, said follower means being affixed for translational movement whereby rotation of said shaft means translates said follower means for controlling said valve body.
Claim 14
Dependent Claim
110 words
A valve operating mechanism for controlling movement of a valve body comprising: shaft means for rotating in response to an input setting; camming means for variably programming movement of said valve body, said camming means being affixed to said shaft means for rotation therewith and having a channel, said camming means having segments for forming said channel; bridging means disposed in said channel for forming continuous, opposing camming surfaces in said channel, said camming surfaces having a predetermined contour; and follower means for engaging said bridging means, said follower means being affixed for translational movement whereby rotation of said shaft means translates said follower means for controlling said valve body.
Claim 15
Dependent Claim
45 words
The valve operating mechanism of claim 11 wherein the segments of said camming means for forming said channel comprise a plurality of generally C-shaped elements, each of said elements being individually adjustable to vary the contour of said opposing camming surfaces in said bridging means.
Claim 16
Dependent Claim
53 words
The valve operating mechanism of claim 12 wherein said bridging means comprise flexible springs, said springs engaging said C-shaped elements in said camming means. 14 The valve operating mechanism of claim 11 including actuator means for controlling said valve body, said actuator means being coupled to said follower means for translational movement therewith.
