Fuel pressure regulator housing
View Patent ↗A housing for a fuel pressure regulator includes a body having a fuel inlet, a fuel outlet, a plurality of retention members, a bypass fitting, and preferably an electrical fitting and a ground fitting. Each retention member includes a catch that is constructed to engage and securely hold the fuel pressure regulator in the housing, while the fuel inlet, the fuel outlet and the bypass passage permit fuel routing as pressurized fuel passes through the fuel pressure regulator. The regulator housing preferably is made of an electrostatic charge dissipative material and is formed in one piece using a single manufacturing process such as injection molding.
1. A housing for holding a regulator that has a housing in which a valve is carried, comprising:
a body adapted to receive a portion of the regulator housing;
at least one inlet passage formed with said body;
at least one outlet passage and at least one bypass passage each formed with said body and in fluid communication with said at least one inlet passage; and
at least one retention member formed with said body and constructed to engage said regulator housing to retain the position of the regulator relative to the body.
2. The housing of claim 1 wherein said body comprises a base and a wall at least partially defining a pocket, wherein said pocket is constructed to receive at least a portion of said regulator.
3. The housing of claim 2 wherein said at least one retention member is carried by said base of said body and projects substantially away from said base and beyond said pocket.
4. The housing of claim 2 wherein said at least one retention member comprises a head having at least one catch formed thereon, the catch being adapted to overlie a portion of the regulator housing.
5. The housing of claim 2 which also comprises a retaining ring that cooperates with said retention member to retain the position of a pressure regulator relative to the body and wherein said at least one retention member comprises a first catch constructed to engage said regulator and a second catch formed on an opposite side of said retention member from said first catch and constructed to engage said retaining ring.
6. The housing of claim 5 wherein said retaining ring comprises at least one recess constructed to receive said second catch of said retention member.
7. The housing of claim 1 wherein said body is composed of an electrostatic charge dissipative material.
8. The housing of claim 1 wherein said at least one bypass passage communicates with a fitting having at least one barb.
9. The housing of claim 8 wherein said barb extends only partially around the circumference of the fitting.
10. The housing of claim 1 further comprising an electrical fitting carried by said body.
11. The housing of claim 1 further comprising a ground fitting carried by said body.
12. The housing of claim 3 wherein a plurality of retention members are disposed around a periphery of said pocket with each retaining member including a catch extending inwardly toward the pocket and adapted to overlie a portion of the regulator.
13. A fuel pump modules comprising:
a fuel pump having an inlet and an outlet;
a fuel pressure regulator that fluidly communicates with said outlet and includes a housing; and
a body separate from the housing of the regulator and constructed to retain said fuel pressure regulator, wherein said housing comprises:
at least one inlet passage formed with said body;
at least one outlet passage and at least one bypass passage each formed with said body and in fluid communication with said at least one inlet passage; and
at least one retention member formed with said body and constructed to engage said regulator housing.
14. The fuel pump module of claim 13 wherein said body comprises a base and a wall at least partially defining a pocket, wherein said pocket is constructed to receive at least a portion of said regulator.
15. The fuel pump module of claim 14 wherein said at least one retention member is formed in said base of said body and projects substantially away from said base and beyond said pocket.
16. The fuel pump module of claim 14 wherein said at least one retention member comprises a head having at least one catch formed thereon, with said catch extending toward the pocket.
17. The fuel pump module of claim 14 wherein said at least one retention member comprises a first catch constructed to engage said regulator.
18. The fuel pump module of claim 13 which also includes a retaining ring and said at least one retention member comprises a second catch constructed to engage the retaining ring.
19. The fuel pump module of claim 18 wherein said retaining ring comprises at least one recess constructed to receive said second catch of said retention member.
20. The fuel pump module of claim 13 wherein said body is composed of an electrostatic dissipative material.
21. A housing that retains a regulator which has a housing that carries a valve, comprising:
a body defining a pocket in which a portion of the regulator is received;
at least one inlet passage formed with said body;
at least one outlet passage and at least one bypass passage each formed with said body and in fluid communication with said at least one inlet passage; and
a plurality of retention members formed with said body, each retention member having a catch facing inwardly toward the pocket and adapted to overlie and engage the regulator housing to retain the position of the regulator relative to the body.
22. The housing of claim 21 which also comprises a retaining ring adapted to be received around a portion of the regulator housing and around each retention member, and wherein the retention members include a second catch facing outwardly away from the pocket and adapted to overlie the retaining ring to maintain the retaining ring on the retention members.
23. The housing of claim 22 wherein the retaining ring is circumferentially continuous and includes a plurality of holes, with each retention member extending through a separate one of the holes.
