Abstract
Abstract A compensator valve for dispensing a metered fluid supply to utilization apparatus in response to integrated demands imposed by different operational variables of the apparatus. Pressurized fluid received at an inlet is throttled by a spring biased valve as the fluid flows toward a discharge outlet. A sealed chamber juxtaposed to the valve includes an inlet for a connection of vacuum which acts to alter the effective valve bias in accordance with the magnitude of vacuum applied.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
157 words
A valve for the metered dispensing of fluid flow comprising in combination: a. a housing defining a fluid flow passage between an inlet and an outlet; b. connecting means at said inlet for receiving a pressurized supply of fluid flow to be dispensed; c. throttle means located in said passage for regulating total fluid flow to said housing outlet; d. an adjustably presettable biasing member adapted to operate said throttle means as a function of a first demand variable; e. a pneumatic actuator adapted to operate said throttle means from pneumatic signals supplied as a function of a second demand variable; and f. integrating means for effectively controlling the operative actions of said biasing member and said pneumatic actuator for said throttle means to regulate fluid flow in correlation to an integrated function of said first and second demand variables including a predetermined offset of conflicting actions imposed on said throttle means by the respective demand variables.
Claim 2
Dependent Claim
157 words
A valve for the metered dispensing of fluid flow comprising in combination: a. a housing defining a fluid flow passage between an inlet and an outlet; b. connecting means at said inlet for receiving a pressurized supply of fluid flow to be dispensed; c. throttle means located in said passage for regulating total fluid flow to said housing outlet; d. an adjustably presettable biasing member adapted to operate said throttle means as a function of a first demand variable; e. a pneumatic actuator adapted to operate said throttle means from pneumatic signals supplied as a function of a second demand variable; and f. integrating means for effectively controlling the operative actions of said biasing member and said pneumatic actuator for said throttle means to regulate fluid flow in correlation to an integrated function of said first and second demand variables including a predetermined offset of conflicting actions imposed on said throttle means by the respective demand variables.
Claim 3
Dependent Claim
21 words
A valve according to claim 1 in which said actuator is operatively responsive to pneumatic signals in the vacuum pressure range.
Claim 4
Dependent Claim
26 words
A valve according to claim 1 in which said biasing member and said actuator are inter-connected for said integrating means to effect a mutual interaction therebetween.
Claim 5
Dependent Claim
62 words
A valve according to claim 3 in which said throttle means comprises a valve disc cooperating with an annular seat in said passage surrounding said housing inlet, and said biasing member is operative for urging said disc in a first direction relative to said seat and said actuator is operative for urging said disc in an opposite direction relative to said seat.
Claim 6
Dependent Claim
60 words
A valve according to claim 4 in which said biasing member comprises a first spring and said actuator comprises an enclosed chamber, a piston operably movable within said chamber in response to receipt of said pneumatic signals, and a second spring located in said chamber acting against said piston in opposition to the movement imposed by said received pneumatic signals.
Claim 7
Dependent Claim
50 words
A valve according to claim 5 in which said first spring is maintained in compression for urging said disc toward a closing relation with said seat and said actuator operates in response to its received signals to vary the degree of compression imposed by said first spring against said disc.
Claim 8
Dependent Claim
62 words
A valve according to claim 4 including a flexible diaphragm member supporting said disc for movement toward and away from said seat, said diaphragm member being operably engaged on one surface by said biasing member and adapted to be operably engaged on the opposite surface by fluid pressure in said passage acting to oppose urging of said disc by said biasing membEr.
Claim 9
Dependent Claim
32 words
A valve according to claim 5 in which said biasing member comprises a spring and said actuator comprises on enclosed chamber at least a portion of which is defined by said diaphragm.
Claim 10
Dependent Claim
31 words
A valve according to claim 1 including condition responsive means operative to alter the effective level of pneumatic signal supplied to said actuator as a function of a remote condition variable.
Claim 11
Dependent Claim
37 words
A valve according to claim 9 in which said condition responsive means comprises a variable bleed connected to said actuator in parallel with the supplied pneumatic signal for controllably offsetting the effective level of said supplied signal.
Claim 12
Dependent Claim
32 words
A valve according to claim 10 in which said condition responsive means comprises a temperature sensitive element operable to vary said bleed in accordance with temperature change to which it is sensitive.
