Flow through pressure regulator

DETAILED DESCRIPTION Referring to FIG.
1, there is illustrated a flow through pressure regulator 10 having a first cup shaped cover means 12 and a second cup shaped cover means 14 which are crimped together to form an unitary hollow member.
In the axially aligned center of the enclosed end 16 of the first cover 12 is an outlet port 18 wherein fuel flows out of the regulator 10.
Around the bottom 20 of the enclosed end 22 of the second cover 14 is located at least one fuel inlet aperture 24 for receiving fuel into the regulator 10.
Referring to FIG.
2, a cross-sectional view of the regulator 10, the first cover 12 has a dimpled center portion 26 in the enclosed end 16 forming the fuel outlet port 18 and a spring locator means 28.
A bias means such as a spring 30 functions to bias the valve seat member 36 of the regulator 10 at a predetermined amount of pressure which relates to the pressure desired by the regulator.
The other end of the spring 30 is located in a spring retainer 34 that is secured to a valve seat member 36 mounted in a central aperture 38 in a diaphragm 40.
The diaphragm 40 is supported around its circumference on a circumferential flange 42 radially extending from the open end 44 of the second cover 14 and is crimped between a circumferential flange 46 extending radially outward of the open end 48 of the first cover 12.
The flange 42 of the second cover 14 is rolled over the circumferential edge of the first cover 12 and crimped to form the unitary member.
At the enclosed end 22 of the second cover 14 is a valve actuator housing means 50 which is secured to the second cover 14.
Both the first 12 and second 14 covers are essentially cup shaped tubular members which are closed at one end and opened at the other end forming a first chamber 52 in the first cover 12 and a second chamber 54 in the second cover 14.
Referring to FIGS.
5 and 6, there is illustrated the valve seat member 36 as found in both the embodiment s illustrated in FIGS.
1 and 3.
Mounted in the central aperture 38 of the diaphragm 40 is a valve seat member 36 which is secured to the diaphragm by means of a flange 56 on the valve seat member 36 and the spring retainer 34
