Abstract

Abstract A fuel pressure regulator comprising a housing, a diaphragm dividing the housing into a first chamber and second chamber, a passage from the exterior of the housing to the first chamber, an inlet and an outlet associated with the second chamber of the housing, and a valve seat associated with the outlet. A carrier is mounted on and movable with the diaphragm and a first spring within the first chamber yieldingly urges the carrier toward the valve seat. The carrier supports a plate that has an opening therein. A valve has a hollow tubular closed end portion that projects through the opening in the plate for engagement with the valve seat and a peripheral portion that retains the valve between the carrier and the plate. A second spring is interposed between the carrier and extends into the tubular portion of the valve to yieldingly urge the valve toward the valve seat and permit relative movement between the valve and the valve seat. The opening of the plate is larger than the tubular portion of the valve and the valve is movable transversely to provide for proper centering of the valve in the valve seat.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 165 words
A fuel pressure regulator comprising a housing, a diaphragm dividing the housing into a first chamber and second chamber, a passage from the exterior of the housing to said first chamber, an inlet and an outlet associated with the second chamber of the housing, a valve seat associated with the outlet, a carrier mounted on and movable with the diaphragm, a spring within the first chamber yieldingly urging the carrier toward the valve seat, said carrier supporting a plate that has an opening therein, a valve having a hollow tubular closed end portion that projects through said opening in the plate for engagement with said valve seat, said valve having a peripheral portion that retains said valve between said carrier and said plate, a second spring interposed between said carrier and extending into the tubular portion of the valve to yieldingly urge said closed end tubular portion of said valve toward the valve seat and permit relative movement between said valve and said valve seat.
Claim 2
Dependent Claim 165 words
A fuel pressure regulator comprising a housing, a diaphragm dividing the housing into a first chamber and second chamber, a passage from the exterior of the housing to said first chamber, an inlet and an outlet associated with the second chamber of the housing, a valve seat associated with the outlet, a carrier mounted on and movable with the diaphragm, a spring within the first chamber yieldingly urging the carrier toward the valve seat, said carrier supporting a plate that has an opening therein, a valve having a hollow tubular closed end portion that projects through said opening in the plate for engagement with said valve seat, said valve having a peripheral portion that retains said valve between said carrier and said plate, a second spring interposed between said carrier and extending into the tubular portion of the valve to yieldingly urge said closed end tubular portion of said valve toward the valve seat and permit relative movement between said valve and said valve seat.
Claim 3
Dependent Claim 25 words
The fuel pressure regulator set forth in claim 1 wherein said valve includes a planar peripheral portion which extends radially outwardly from said tubular portion.
Claim 4
Dependent Claim 38 words
The fuel pressure regulator set forth in claim 1 wherein the opening in said plate has a greater diameter than said tubular portion of the valve to permit transverse movement of said valve relative to said valve seat.
Claim 5
Dependent Claim 38 words
The fuel pressure regulator set forth in claim 3 wherein said valve includes a groove in the plane of said plate such that the valve may move so that a portion of the plate extends into said groove.
