Abstract
Abstract A sequencing valve which distributes line pressure from a single-inlet flow line, sequentially, through a plurality of outlet flow lines as a selective function of pulsating line pressure or an independently operated pilot valve. The sequencing valve includes a housing having a valving member positioned between the inlet line and the outlet lines. The valving member consists of a number of pie-shaped hinged flaps or valve elements corresponding to the number of outlet lines. Each flap is sequentially raised by a lifting foot which undergoes reciprocable and step-by-step rotatable movement in response to changes in inlet line pressure or pilot valve operation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
Sequencing valve means, comprising; a housing having an inlet port in open fluid communication with the upstream side of each of a plurality of valve elements pivotally mounted adjacent one peripheral edge thereof for individual opening movement in an upstream direction and closing movement in a downstream direction relative to a like plurality of outlet ports in said housing, actuator means including a pressure-responsive actuator and valve lifter means engageable with an opposite peripheral edge of each said valve element for sequentially opening and closing individual ones of said valve elements in response to pressure differentials across said actuator.
Claim 2
Dependent Claim
99 words
Sequencing valve means, comprising; a housing having an inlet port in open fluid communication with the upstream side of each of a plurality of valve elements pivotally mounted adjacent one peripheral edge thereof for individual opening movement in an upstream direction and closing movement in a downstream direction relative to a like plurality of outlet ports in said housing, actuator means including a pressure-responsive actuator and valve lifter means engageable with an opposite peripheral edge of each said valve element for sequentially opening and closing individual ones of said valve elements in response to pressure differentials across said actuator.
Claim 3
Dependent Claim
36 words
The sequencing valve means of claim 1 including port means and an independently operated pilot valve for sequentially affording and blocking fluid communication between one side of said pressure-responsive actuator and a region of lower pressure.
Claim 4
Dependent Claim
31 words
The sequencing valve means of claim 2 including bleed means intercommunicating opposite sides of said pressure-responsive actuator, and said bleed means providing a more restricted flow passage than said port means.
Claim 5
Dependent Claim
53 words
The sequencing valve means of claim 1 wherein said valve means includes a lifting foot positioned for individual engagement with the downstream side of selected ones of said valve elements for lifting the same in the upstream direction; and cam means intermediate said pressure-responsive actuator and lifting foot for selecting said individual engagement.
Claim 6
Dependent Claim
19 words
The sequencing valve means of claim 4 including a lost motion connection between said pressure-responsive actuator and lifting foot.
Claim 7
Dependent Claim
25 words
The sequencing valve meanS of claim 1 including means for reducing the pressure on one side of said pressure-responsive actuator for producing said pressure differentials.
Claim 8
Dependent Claim
25 words
The sequencing valve means of claim 1 including means for increasing the pressure on one side of said pressure-responsive actuator for producing said pressure differentials
Claim 9
Dependent Claim
120 words
A sequencing valve, comprising: a housing having an inlet port and a plurality of outlet ports, a valve element pivotally mounted adjacent one side of each of said outlet ports for individual opening movement in an upstream direction and closing movement in a downstream direction, a pressure-responsive actuator, valve lifter means mounted in said housing on a side of said outlet ports remote from said one side for selectively engaging individual ones of said valve elements at a location thereon remote from the pivotal mounting thereof for opening the same, and means including said pressure-responsive actuator for actuating said filter means for sequentially opening and closing individual ones of said valve elements in response to pressure differentials across said actuator.
Claim 10
Dependent Claim
120 words
A sequencing valve, comprising: a housing having an inlet port and a plurality of outlet ports, a valve element pivotally mounted adjacent one side of each of said outlet ports for individual opening movement in an upstream direction and closing movement in a downstream direction, a pressure-responsive actuator, valve lifter means mounted in said housing on a side of said outlet ports remote from said one side for selectively engaging individual ones of said valve elements at a location thereon remote from the pivotal mounting thereof for opening the same, and means including said pressure-responsive actuator for actuating said filter means for sequentially opening and closing individual ones of said valve elements in response to pressure differentials across said actuator.
