Abstract
Abstract A valve having a seat which is caused to rotate about its axis between different rotational positions by power means which is independent of the power means by which the closure member is moved between opened and closed positions. Operation of the power means for rotating the seat may be initiated by means automatically responsive to movement of the closure member into a predetermined position or by means independent of movement of the closure member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
89 words
A valve, comprising a body having a flowway therethrough, a closure member within the body and movable by power means between positions opening and closing the flowway, a seat mounted within the flowway for engaging a side of the closure member, power means for rotating the seat about its axis and between different rotational positions independently of the power means for moving the closure member, and means for initiating operation of the seat rotating power means automatically in response to movement of said closure member into a predetermined position.
Claim 2
Dependent Claim
89 words
A valve, comprising a body having a flowway therethrough, a closure member within the body and movable by power means between positions opening and closing the flowway, a seat mounted within the flowway for engaging a side of the closure member, power means for rotating the seat about its axis and between different rotational positions independently of the power means for moving the closure member, and means for initiating operation of the seat rotating power means automatically in response to movement of said closure member into a predetermined position.
Claim 3
Dependent Claim
30 words
A valve of the character defined in claim 1, including means by which operation of said seat rotating power means may be initiated independently of movement of said closure member.
Claim 4
Dependent Claim
97 words
A valve, comprising a body having a flowway therethrough, a closure member within the body and movable by power means between positions opening and closing the flowway, a seat mounted within the flowway for engaging a side of the closure member, an actuator having a part engageable with the seat for rotating it about its axis and between different rotational positions independently of the power means for moving the closure member, and means automatically responsive to movement of said closure member into a predetermined position for activating said actuator to cause it to so rotate the seat.
Claim 5
Dependent Claim
97 words
A valve, comprising a body having a flowway therethrough, a closure member within the body and movable by power means between positions opening and closing the flowway, a seat mounted within the flowway for engaging a side of the closure member, an actuator having a part engageable with the seat for rotating it about its axis and between different rotational positions independently of the power means for moving the closure member, and means automatically responsive to movement of said closure member into a predetermined position for activating said actuator to cause it to so rotate the seat.
Claim 6
Dependent Claim
25 words
A valve of the character defined in claim 3, including means by which said actuator may be activated independently of movement of said closure member.
Claim 7
Dependent Claim
33 words
A valve of the character defined in claim 3, wherein said actuator is mounted on the valve body and said part is movable with respect to said body for so engaging the seat.
Claim 8
Dependent Claim
119 words
A valve, comprising a body having a flowway therethrough, a closure member within the body and movable by power means between positions opening and closing the flowway, a seat mounted within the flowway for engaging a side of the closure member, a rod mounted on the body for reciprocation with respect thereto and having a part thereon engageable with the seat, during such reciprocation, to rotate said seat about its axis and between different rotational positions, means for reciprocating the rod and thereby rotating the seat independently of the power means for moving the closure member, and means for initiating operation of the rod reciprocating means automatically in response to movement of the closure member to a predetermined position.
Claim 9
Dependent Claim
119 words
A valve, comprising a body having a flowway therethrough, a closure member within the body and movable by power means between positions opening and closing the flowway, a seat mounted within the flowway for engaging a side of the closure member, a rod mounted on the body for reciprocation with respect thereto and having a part thereon engageable with the seat, during such reciprocation, to rotate said seat about its axis and between different rotational positions, means for reciprocating the rod and thereby rotating the seat independently of the power means for moving the closure member, and means for initiating operation of the rod reciprocating means automatically in response to movement of the closure member to a predetermined position.
Claim 10
Dependent Claim
29 words
A valve of the character defined in claim 6, including means by which operation of the rod reciprocating means may be initiated independently of movement of said closure member.
Claim 11
Dependent Claim
32 words
A valve of the character defined in claim 7, wherein the rod extends through the valve body, and the means for reciprocating the rod is mounted on the outside of the body.
Claim 12
Dependent Claim
34 words
A valve of the character defined in claim 7, wherein said means for reciprocating the rod includes a cylinder fixed to the body, and a piston in the cylinder and connected to the rod.
Claim 13
Dependent Claim
28 words
A valve of the character defined in claim 9, wherein the cylinder is mounted on the outside of the valve body and the rod extends through said body.
Claim 14
Dependent Claim
33 words
A valve of the character defined in claim 6, wherein the closure member is ball shaped, and the rod reciprocates in a direction perpendicular to the axis of the opening throuGh the seat.
