Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
154 words
An actuating mechanism for regulating the flow of fluid through a linear series of admission valves including a frame mounted adjacent to the valve series having two parallel rows of roller bearings supported within said frame, each bearing row being located within the linear plane described by the valve series, a planar cam bar mounted for movement within said linear plane between the two parallel rows of bearings, the bar having two parallel opposed walls containing grooves being arranged to ride in moving contact with said two rows of bearings as said bar moves in said plane, cam tracks formed in said bar, each track being operatively connected to one of said valves in said series for translating a lifting motion thereto, and means to reciprocate said cam bar within said plane whereby said valves are opened and closed in a prescribed order in response to the motion translated thereto by said cam tracks.
Claim 2
Dependent Claim
154 words
An actuating mechanism for regulating the flow of fluid through a linear series of admission valves including a frame mounted adjacent to the valve series having two parallel rows of roller bearings supported within said frame, each bearing row being located within the linear plane described by the valve series, a planar cam bar mounted for movement within said linear plane between the two parallel rows of bearings, the bar having two parallel opposed walls containing grooves being arranged to ride in moving contact with said two rows of bearings as said bar moves in said plane, cam tracks formed in said bar, each track being operatively connected to one of said valves in said series for translating a lifting motion thereto, and means to reciprocate said cam bar within said plane whereby said valves are opened and closed in a prescribed order in response to the motion translated thereto by said cam tracks.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1 wherein at least two rollers in each row are in rolling contact with said cam bar at all times as the bar moves through its reciprocating path of travel.
Claim 4
Dependent Claim
58 words
The apparatus of claim 1 wherein each cam track is a clear aperture passing through the planar walls of the bar and being operatively connected to one of said valves by a bifurcated member, the arms of which span the planar walls of the bar and are pivotally connected to a cam follower passing through the cam track.
Claim 5
Dependent Claim
23 words
The apparatus of claim 3 further including a biasing means for urging the cam follower against the working profile of the cam track.
Claim 6
Dependent Claim
38 words
The apparatus of claim 4 wherein the cam tracks are arranged to translate motion to more than one valve in the series at one time whereby the opening of said valves can be controlled in an overlapping order.
Claim 7
Dependent Claim
33 words
The apparatus of claim 1 further including means for adjusting the positioning of said bearing surfaces in respect to the cam bar whereby the distance between the bar and the valves is controllable.
