Definitions
- Valve object of the invention is a valve having a housing, a solenoid disposed in the housing, a movable pin of the solenoid and a piston connected to the pin, wherein a second housing part is provided, which bears against the housing and partially receives the piston.
- valves are used, inter alia, as a diverter valve on the turbocharger in motor vehicles to release a bypass to the suction side in overrun and are thus known.
- the valve seat is formed by the housing of the turbocharger to which the valve is flanged.
- the axially displaceable piston must be sealed against the housing.
- the existing plastic second housing part is connected by means of a latching connection with the first housing part.
- the existing reasons of weight plastic second housing part has a reaching from ⁇ strength and production reasons, a certain structure and wall thickness have. This has the consequence that a corresponding space must be provided.
- Such valves are therefore only conditionally adaptable to different installation spaces.
- the invention is therefore an object of the invention to provide a valve which allows its use in different installation locations of its construction.
- the problem is solved by the fact that the second housing part consists of metal. ⁇
- the formation of the second housing part made of metal has the advantage that it can be formed with respect to a plastic part with a significantly reduced wall thickness due to the higher strength of plastic.
- the smaller wall thickness allows a smaller one for the same piston diameter
- Diameter of the second housing part Diameter of the second housing part.
- the valve can thus be mounted in smaller openings.
- the seal can be made smaller in diameter, resulting in an improved seal.
- a metallic second housing part allows connection to the housing via a latching connection or other connections.
- a good resistance to various fürströ ⁇ Menden media and media mixtures thereof, preferably the exhaust gas of an internal combustion engine is achieved in an advantageous embodiment by the fact that the metal is a stainless steel, preferably a chrome-nickel steel.
- the second housing part can be manufactured according to a further exemplary front part ⁇ embodiment particularly cost-effective as a deep-drawn part ⁇ .
- the shape of the housing part can be achieved in just one step without further processing.
- a wall thickness of 0.3 mm to 3 mm, preferably 0.5 mm to 1 mm of the second housing part is sufficient to provide sufficient strength and thus safe operation of the To ensure valve.
- the second housing part on one of its side facing the housing on a radially outwardly projecting edge.
- the edge can be used to create a defined stop surface for placement on the housing. The edge is particularly easy to do that and thus produce cost-effective in the shaping of the second Ge ⁇ housing part by deep drawing.
- the radially outwardly projecting edge can be used to connect the second housing part with the housing.
- the edge can be placed on the one hand on the housing.
- the edge and thus the second housing part between the housing and the other component can be clamped and fixed in position.
- the radially outwardly projecting edge can be clipped into correspondingly formed latching hooks on the housing so as to achieve a reliable seat on the housing via such a latching connection.
- the second housing part is pressed with the housing.
- the second housing part is pressed with a cast-in in the housing return element of the solenoid.
- the advantage of this embodiment is that return elements made of metal and thus have a much higher process stability during compression, as in a pressing of the second housing part with a plastic part.
- the return ⁇ closing element is already present in the valve component, whereby no additional component for pressing with the second housing part is needed.
- the return element has a directed toward the piston cylindrical portion to which the second housing part is pressed.
- the return element has a Ein ⁇ guideway for the second housing part.
- the radially outwardly projecting edge of the second housing part can be used as a point of application for a pressing tool. Further, this edge can be used for pressing as a stop on the housing, so as to ensure a proper execution of the press connection. This means that a reliable connection of the second housing part with the housing is achieved when the second housing part is pressed on so far that the edge rests against the housing.
- the second housing part has on its side facing away from the housing a radially inwardly directed collar.
- the advantage is that the collar can be used as a receptacle of a seal.
- a further embodiment is to clamp the seal on the collar.
- Particularly advantageous is the use of the return element of the solenoid, since in this way no additional component is needed.
- Another advantage is that the fixing of the seal can be done in one step with the pressing. Possible process-related tolerances during pressing influence this Clamping the seal not, because due to the elasticity of the seal such tolerances are compensated.
- the seal arranged in the housing is connected to the second housing part in order to seal the valve against the line.
- This configuration allows the gasket to be preassembled with the second housing part, which facilitates final assembly of the valve.
- the seal has radially inwardly a slot in which engages the radially outwardly directed edge of the second housing part.
- Fig. 1 is a sectional view of a valve according to the prior art and Fig. 2 is a sectional view of an inventive
- Figure 1 shows the valve comprising a housing 1 with integrally molded socket 2 for electrically connecting the valve.
- the housing 1 further has an integrally formed flange 3 and three bores 3a, via which the housing 1 is flanged to a turbocharger, not shown, in the region of the bypass line 4.
- a second housing part 13 made of plastic connects to the flange 3.
- the second housing part 13 is connected by means of a latching connection 14 with the housing 1.
- a solenoid 5 with a coil 6 and a metal pin 7 is arranged in the housing 1, a solenoid 5 with a coil 6 and a metal pin 7 is arranged.
- the metal pin 7 is connected to a pot-shaped piston 8, which has an axially projecting annular sealing surface 10 at the periphery of its bottom 9.
- the sealing surface 10 rests on the valve seat 11 to close the bypass line 4, so that no medium from the line 4 in the line 12 can flow.
- a spring 7 a presses the piston 8 in the direction of the valve
- the valve in Figure 2 has substantially the same structure as the valve in Fig. 1.
- the consisting of a chromium-nickel steel second housing part 13 has a wall thickness of 0.5 mm and is a deep-drawn part.
- the second housing part 13 has a radially outwardly directed edge 15.
- Concentric with the edge 15, an O-ring acting as a seal 16 is arranged in the housing 1 in the housing 1.
- the solenoid 7 has a return element 17, which is encapsulated by the plastic of the housing 1. In its axial extent, the return element 17 has a directed toward the piston cylindrical portion 18 which has at its end acting as a chamfer chamfer 19.
- the second housing part 13 is pressed onto the cylindrical portion 18 so far that the edge 16 rests against the housing 1.
- the second housing part 13 has at its end remote from the housing 1 a radially inwardly directed collar 20, on which a seal 21 rests against the piston 8 for sealing.
- the axial extent of the second housing part 13 is chosen so that the seal 21 is clamped between collar 2 and section 18 and thus fixed in position.
