Abstract
Abstract A fuel pressure regulator has a base (10) having a rim (52) staked over a flange (40) of a pressure regulator cover (42), and a compression ring (44) concentrates the clamping effort of the cover on a circular area of a sealing region (36) of a diaphragm (16) of the pressure regulator.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
170 words
A fuel pressure regulator comprising a pressure regulator base (10) having an annular clamping surface (38), a pressure regulator diaphragm (16) having an annular sealing region (36) overlying the clamping surface (38), and a cover (42) having an annular flange (40) overlying the sealing region (36), the base (10) having a rim (52) surrounding and extending axially from the clamping surface (38), and the rim (52) being staked over the flange (40) to cause the flange (40) to clamp the diaphragm sealing region (36) against the annular clamping surface (38), characterised in that an annular compression ring (44) is disposed between the flange (40) and the diaphragm sealing region (36), and the compression ring (44) has an inner edge (46) spaced from the diaphragm (16), a circular intermediate area (48) engaging the diaphragm sealing region (36), and an outer edge (50) engaging the flange (40), the compression ring (44) being effective to concentrate the clamping effort of the flange (40) on a circular area of the diaphragm sealing region (36).
Claim 2
Dependent Claim
170 words
A fuel pressure regulator comprising a pressure regulator base (10) having an annular clamping surface (38), a pressure regulator diaphragm (16) having an annular sealing region (36) overlying the clamping surface (38), and a cover (42) having an annular flange (40) overlying the sealing region (36), the base (10) having a rim (52) surrounding and extending axially from the clamping surface (38), and the rim (52) being staked over the flange (40) to cause the flange (40) to clamp the diaphragm sealing region (36) against the annular clamping surface (38), characterised in that an annular compression ring (44) is disposed between the flange (40) and the diaphragm sealing region (36), and the compression ring (44) has an inner edge (46) spaced from the diaphragm (16), a circular intermediate area (48) engaging the diaphragm sealing region (36), and an outer edge (50) engaging the flange (40), the compression ring (44) being effective to concentrate the clamping effort of the flange (40) on a circular area of the diaphragm sealing region (36).
Claim 3
Dependent Claim
37 words
A fuel pressure regulator according to claim 1, characterised in that the inner edge of the compression ring (44) comprises a free inner edge (46) which is spaced from the diaphragm (16) and from the cover (42).
