Abstract

Abstract A fuel pressure regulator assembly comprising a housing, a diaphragm separating the housing into a first and second chamber. The housing has a radial inlet extending to the first chamber and a connector having an axial outlet is mounted in the housing and extends axially into the first chamber. The connector supports a sealing ring. The diaphragm supports a valve member that is adapted to engage the sealing ring, and a spring in the second chamber urges said valve member against the sealing ring. The fuel pressure regulator assembly includes provision for increasing the fuel regulation pressure by varying the effective diaphragm area.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 182 words
A fuel pressure regulator assembly comprising a housing, a first diaphragm separating said housing into a first and second chamber, said housing having a fuel inlet extending to said first chamber, a connector mounted in said housing and extending axially into said first chamber, said connector having an axial fuel outlet, a sealing ring of resilient material, interengaging means between said sealing ring and said connector for mounting said sealing ring on said connector such that a portion of said sealing ring projects axially beyond said connector, said first diaphragm having a valve member adapted to engage said sealing ring, and spring means in said second chamber urging said valve member against said sealing ring, a second diaphragm defining a third chamber between said first and second chambers, said second diaphragm being movable with said valve member, said valve member having an opening therethrough providing communication between said first chamber and said third chamber, a solenoid in said second chamber of said housing having a plunger extending into said third chamber and operable to control the axial opening in said valve member.
Claim 2
Dependent Claim 182 words
A fuel pressure regulator assembly comprising a housing, a first diaphragm separating said housing into a first and second chamber, said housing having a fuel inlet extending to said first chamber, a connector mounted in said housing and extending axially into said first chamber, said connector having an axial fuel outlet, a sealing ring of resilient material, interengaging means between said sealing ring and said connector for mounting said sealing ring on said connector such that a portion of said sealing ring projects axially beyond said connector, said first diaphragm having a valve member adapted to engage said sealing ring, and spring means in said second chamber urging said valve member against said sealing ring, a second diaphragm defining a third chamber between said first and second chambers, said second diaphragm being movable with said valve member, said valve member having an opening therethrough providing communication between said first chamber and said third chamber, a solenoid in said second chamber of said housing having a plunger extending into said third chamber and operable to control the axial opening in said valve member.
Claim 3
Dependent Claim 45 words
The fuel pressure regulator set forth in claim 1 including a fuel filter associated with said first diaphragm and said first chamber and cleaned by turbulence when said sealing ring is in engagement with said valve member to prevent fuel flow to said first chamber.
Claim 4
Dependent Claim 46 words
The fuel pressure regulator assembly set forth in claim 2 wherein said fuel filter comprises a member associated with the said first diaphragm and comprising spaced grooves defining spaced rings adapted to engage said second diaphragm and radial slots in said rings adjacent said first diaphragm.
