Pressure regulator for a fuel supply unit
View Patent ↗Disclosed is a pressure regulator for a fuel supply unit of a motor vehicle comprising a valve for joining a connection to an outlet above a designated pressure in the connection, a valve body and a valve seat, and a spring element for prestressing the valve body against the valve seat, characterized in that the valve body is designed as a sheet-metal part.
1. A pressure regulator for a fuel supply unit of a motor vehicle, comprising:
a valve for joining a connection to an outlet above a designated pressure in the connection;
a valve body;
a moveable valve seat;
a spring element for prestressing the valve seat against the valve body; and
a support part joined to the valve body and arranged within the pressure regulator to maintain two opposing housing parts of the pressure regulator at a spaced apart distance from each other;
wherein the valve body is a sheet-metal part.
2. The pressure regulator as claimed in claim 1 , wherein the valve body comprises a spherical cap on a side of the valve body facing the valve seat.
3. The pressure regulator as claimed in claim 1 , wherein that side of the valve body which faces the valve seat is provided with a coating.
4. The pressure regulator as claimed in claim 3 , wherein the coating is produced from an elastomer.
5. The pressure regulator as claimed in claim 1 , wherein the valve body includes latching hooks for securing the valve body on the support part within the pressure regulator.
6. The pressure regulator as claimed in claim 5 , wherein the support part includes receptacles for receiving the latching hooks of the valve body.
7. The pressure regulator as claimed in claim 5 , wherein the latching hooks are provided with at least one of radial and axial play in relation to the support part within the pressure regulator.
8. The pressure regulator as claimed in claim 5 , wherein the valve body includes spring tongues which are supported on the support part within the pressure regulator.
9. The pressure regulator as claimed in claim 8 , wherein ends of the spring tongues are arranged in at least one of a radially and axially displaceable manner in the support part within the pressure regulator.
10. The pressure regulator as claimed in claim 8 , wherein the valve body includes one of at least three spring tongues and at least three latching hooks.
11. The pressure regulator as claimed in claim 8 , wherein the spring tongues and the latching hooks are distributed in an alternating manner over a circumference of the valve body.
12. A pressure regulator for a fuel supply unit of a motor vehicle, comprising:
a valve for joining a connection to an outlet above a designated pressure in the connection;
a valve body having latching hooks for securing the valve body on a support part of the pressure regulator;
a moveable valve seat; and
a spring element for prestressing the valve seat against the valve body;
wherein the valve body is a sheet-metal part including spring tongues which are supported on the support part within the pressure regulator.
13. The pressure regulator as claimed in claim 12 , wherein the support part includes receptacles for receiving the latching hooks of the valve body.
14. The pressure regulator as claimed in claim 12 , wherein the latching hooks are provided with at least one of radial and axial play in relation to the support part within the pressure regulator.
15. The pressure regulator as claimed in claim 12 , wherein ends of the spring tongues are arranged in at least one of a radially and axially displaceable manner in the support part within the pressure regulator.
16. The pressure regulator as claimed in claim 12 , wherein the valve body includes one of at least three spring tongues and at least three latching hooks.
17. The pressure regulator as claimed in claim 12 , wherein the spring tongues and the latching hooks are distributed in an alternating manner over a circumference of the valve body.
