Abstract
Abstract A housing having a valve seat and a valve member for opening and closing the valve seat. A lever is pivotally carried by the housing and carries the valve member whereby pivoting movement of the lever moves the valve member relative to the valve seat for controlling the same. A movable actuator member is carried by the housing and is operatively interconnected to the lever by a leaf spring so that movement of the actuator member causes pivotal movement of the lever whereby the leaf spring eliminates the need for any adjustments necessary to maintain proper valve closure relative to a seated position of the actuator member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
120 words
A valve construction comprising a housing means having a valve seat, a valve member for opening and closing said valve seat, a pivot member carried by said housing means, a lEver pivotally carried by said pivot member of said housing means and carrying said valve member whereby pivoting movement of said lever moves said valve member relative to said valve seat for controlling the same, a movable actuator member carried by said housing means, and a spring means operatively interconnecting said actuator member to said lever to cause pivotal movement of said lever upon movement of said actuator member, said spring means comprising a leaf spring pivotally carried by said pivot member and being pivotally movable relative to said lever.
Claim 2
Dependent Claim
120 words
A valve construction comprising a housing means having a valve seat, a valve member for opening and closing said valve seat, a pivot member carried by said housing means, a lEver pivotally carried by said pivot member of said housing means and carrying said valve member whereby pivoting movement of said lever moves said valve member relative to said valve seat for controlling the same, a movable actuator member carried by said housing means, and a spring means operatively interconnecting said actuator member to said lever to cause pivotal movement of said lever upon movement of said actuator member, said spring means comprising a leaf spring pivotally carried by said pivot member and being pivotally movable relative to said lever.
Claim 3
Dependent Claim
38 words
A valve construction as set forth in claim 1 wherein said housing means has another valve seat, and another valve member for opening and closing said other valve seat, said other valve member being carried by said lever.
Claim 4
Dependent Claim
104 words
A valve construction as set forth in claim 2 wherein said actuator has two positions relative to said housing means, said spring means causing said other valve member to be in open position relative to said other valve seat and the first-mentioned valve member to be closed against its respective valve seat when said actuator member is in one of its said positions, said spring means causing said other valve member to be closed against said other valve seat and the first-mentioned valve member to be open relative to its respective valve seat when said actuator member is in the other of its positions.
Claim 5
Dependent Claim
47 words
A valve construction as set forth in claim 3 wherein said housing means has an internal chamber, said valve seats projecting into said chamber, said housing means having a passage means therein leading to said chamber and being interconnected by said chamber to the opened valve seat.
Claim 6
Dependent Claim
33 words
A valve construction as set forth in claim 4 wherein said valve seats and said passage means of said housing means are respectively provided in three nipple means carried by said housing means.
Claim 7
Dependent Claim
30 words
A valve construction as set forth in claim 1 wherein another spring means is carried by said housing means and tends to move said lever to one pivotal position thereof.
Claim 8
Dependent Claim
155 words
A solenoid operated valve construction comprising a housing means having a valve seat, a valve member for opening and closing said valve seat, a pivot member carried by said housing means, a lever pivotally carried by said pivot member of said housing means and carrying said valve member whereby pivoting movement of said lever moves said valve member relative to said valve seat for controlling the same, an axially movable solenoid armature member carried by said housing means, electrical coil means carried by said housing means for causing axial movement of said armature member from a seated position thereof to an actuated position thereof, and a spring means operatively interconnecting said solenoid member to said lever to cause pivotal movement of said lever upon axial movement of said solenoid member between said positions thereof, said spring means comprising a leaf spring pivotally carried by said pivot member and being pivotally movable relative to said lever.
Claim 9
Dependent Claim
155 words
A solenoid operated valve construction comprising a housing means having a valve seat, a valve member for opening and closing said valve seat, a pivot member carried by said housing means, a lever pivotally carried by said pivot member of said housing means and carrying said valve member whereby pivoting movement of said lever moves said valve member relative to said valve seat for controlling the same, an axially movable solenoid armature member carried by said housing means, electrical coil means carried by said housing means for causing axial movement of said armature member from a seated position thereof to an actuated position thereof, and a spring means operatively interconnecting said solenoid member to said lever to cause pivotal movement of said lever upon axial movement of said solenoid member between said positions thereof, said spring means comprising a leaf spring pivotally carried by said pivot member and being pivotally movable relative to said lever.
Claim 10
Dependent Claim
40 words
A solenoid operated valve construction as set forth in claim 7 wherein said housing means has another valve seat, and another valve member for opening and closing said other valve seat, said other valve member being carried by said lever.
Claim 11
Dependent Claim
92 words
A solenoid operated valve construction as set forth in claim 8 wherein said spring means causes said other valve member to be in open position relative to said other valve seat and the first-mentioned valve member to be closed against its respective valve seat when said solenoid member is in its seated position, said spring means causing said other valve member to be closed against said other valve seat and the first-mentioned valve member to be open relative to its respective valve seat when said solenoid member is in its actuated position.
Claim 12
Dependent Claim
49 words
A solenoid operated valve construction as set forth in claim 9 wherein said housing means has an internal chamber, said valve seats projecting into said chamber, said housing means having a pAssage means therein leading to said chamber and being interconnected by said chamber to the opened valve seat.
Claim 13
Dependent Claim
35 words
A solenoid operated valve construction as set forth in claim 10 wherein said valve seats and said passage means of said housing means are respectively provided in three nipple means carried by said housing means.
Claim 14
Dependent Claim
32 words
A solenoid operated valve construction as set forth in claim 7 wherein another spring means is carried by said housing means and tends to move said lever to one pivotal position thereof.
