Definitions
- the invention relates to a pressure regulator for a fuel delivery unit of a motor vehicle with a valve for Ver ⁇ connection of a connection with an outlet above a designated pressure in the terminal, with a valve body and a valve seat and with a spring element for biasing the valve body against the valve seat.
- valve body is usually designed as a ball and seals below an intended pressure relative to the valve seat.
- the outlet is disposed on the terminal against ⁇ opposite side of the valve seat.
- the ball is lifted above the intended pressure from the pressure in the connection of the valve seat, so that fuel can flow over to the outlet.
- the ball is usually polished or lapped.
- a disadvantage of the known pressure regulator is that it requires a very complex manufacturing process for producing the valve body. Furthermore, the valve body formed as a ball ⁇ requires a complex guide in the pressure Regier
- the invention is based on the problem to design a pressure regulator of the type mentioned so that it is structurally particularly simple and inexpensive to manufacture. This problem is inventively achieved in that the valve body is designed as a sheet metal part.
- the pressure regulator according to the invention makes it particularly easy to guide the valve body. Since the sheet-metal part can be made considerably lighter and flatter than the ball of the known pressure regulator, the pressure regulator according to the invention has particularly small dimensions. Furthermore, the valve body can be produced particularly cost-effectively, for example by stamping. As a result, the pressure regulator according to the invention is structurally particularly simple and can be produced cost- effectively .
- a tolerance compensation between the valve seat arranged on a bore and the valve body can be easily produced according to an advantageous development of the invention if the valve body has the shape of a spherical cap on its side facing the valve seat.
- Another we ⁇ sentaji advantage is that the spherical cap has a smaller axial extension than a ball, the valve body according to the invention whereby a particularly flat can be formed, so that the valve body takes up less space in the axial extension.
- the ball cap can also be easily manufactured by forming the sheet metal part.
- the assembly of the valve body is designed according to a ⁇ on their advantageous development of the invention particularly simple when the valve body has latching hooks for mounting on ei ⁇ NEM carrier part.
- the compound of the catch hook with the carrier part is fanned sch ⁇ , when the carrier member correspondingly formed Recordin ⁇ men having for the latching hooks.
- the valve body does not require any elaborate guidance when the latching hooks have a designated clearance relative to the carrier part, in particular a radial play. This has the advantage that as a result of the game, a radial tolerance ⁇ compensation is made possible.
- tolerances in the axial extent between the valve body and the valve seat can also be easily compensated for by virtue of another advantageous refinement of the invention where the valve body has spring tongues supporting the carrier part.
- the fact is used that the latch hook of the valve body ge ⁇ geninate the recordings on the carrier part axial play aufwei- sen. In this way, the valve body can cooperate axially with the stops of the latching hooks on the carrier part and the spring tongues.
- spring tongues Another advantage of the spring tongues is that a particularly flat characteristic curve of the pressure regulator is achieved because the spring tongues lift the valve body even when the piston moves upwards.
- the valve body can be biased without tilting and / or guided if it has at least three spring tongues and / or at least three latching hooks.
- a torsionally rigid mounting of the valve body can be produced according to another advantageous embodiment of the invention with particularly low design effort, when the spring tongues and the latching hooks are arranged alternately distributed over the circumference of the valve body.
- the known pressure regulator arise when striking the valve body designed as a ball on the valve seat stö ⁇ rende noises.
- noises can be reliably avoided if the side of the valve body facing the valve seat has a coating. Furthermore, this ensures ei ⁇ ne reliable tightness at low pressures in the connection.
- FIG. 1 shows a longitudinal section through a pressure regulator according to the invention
- FIG. 2 is a greatly enlarged, perspective view of a valve body of the Druckreg ⁇ coupler according to the invention from FIG. 1
- FIG. 1 shows a pressure regulator according to the invention designed as a flow-through valve with a housing 1 and a piston 2 displaceably arranged in the housing 1.
- the pressure regulator serves to limit a maximum pressure in a feed line (not shown) of a fuel tank a motor vehicle.
- the housing 1 has two of a support member 3 at a distance held housing parts 4, 5.
- the pressure regulator has a connection 6 for a pressure line and an outlet 7.
- the piston 2 is prestressed against a valve body 10 by means of a spring 8 designed as a helical spring with a valve seat 9.
- a diaphragm 11 connected to the carrier part 3 and the piston 2 seals off the region below the piston 2 from the region above the piston 2.
- This will provides relievege ⁇ that is charged at a pressure in the terminal 6 of the plunger 2 against the force of the spring 8 and is moved above a designated pressure, the piston 2, so that the valve seat 9 lifts off from the valve body 10 degrees.
- the housing parts 4, 5 are made of sheet steel and connected by a bead 12 mit ⁇ each other.
- beading 12 is a sealing ring 13 is biased between the support member 3 and the lower housing part 5.
- a spring 8 holding edge 14 of the upper housing part 4 is designed plastically deformable and used to calibrate the pressure regulator and thus to set the intended pressure at which the connection between the terminal 6 and the outlet 7 is generated.
- the valve body 10 is formed as a sheet metal part and has spring tongues 15 and latching hooks 16. With the latching hooks 16, the valve body 10 is connected to the support part 3, wherein the latching hooks 16 are engaged with receptacles 18 of the support part 3.
- the latching hooks 16 are formed with radial and axial play to the receptacles 18.
- the valve body 10 is prestressed in the axial direction by way of the spring tongues 15 and the latching hooks 18 resting on the receptacles 18, the spring tongues 15 allowing a slight movement of the valve body 10 in the axial direction.
- the free end of the spring tongues 15 is radially displaceable on the carrier part 3 is ⁇ assigns.
- valve body 10 is arranged to be movable in the radial direction, so that thereby the radial tolerance compensation is possible. Furthermore reveals Figure 1, is that of the valve seat 9 technically ⁇ protruding region of the valve body 10 forms out of a ball cap ⁇ .
- FIG. 2 shows a greatly enlarged perspective illustration of the lung ⁇ formed as a sheet metal part valve body 10 of Fi gur ⁇ 1.
- a section is located.
- the valve body 10 has in each case three latching hooks 16 and spring tongues 15.
- the latching hooks 16 and the spring ⁇ tongues 15 are distributed at intervals of 120 ° over the circumference of the valve body 10 and alternately ordered to ⁇ .
- FIG. 2 shows that the valve body 10 has on its side facing the valve seat 9 shown in FIG. 1 a coating 17 made of an elastomer.
