Definitions
- the invention relates to a valve comprising a housing, a solenoid arranged in the housing, a pin movable by the solenoid and a cup-shaped piston connected to the pin, a seal cooperating with a valve seat in the bottom region of the piston and a seal or abutment in the piston Area of the open end of 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.
- rapid opening and closing of the valve is an essential prerequisite.
- when closing it depends on the immediate closing Ver by the application of the piston to a valve seat.
- 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 or its movement must be limited.
- the seal At the open end of the piston, the seal has a relatively large sealing lip.
- the size of the sealing lip is required because the piston is displaced with respect to the valve during opening and closing of the valve and the seal must be ensured both at rest and during the piston movement. The same applies to a stop.
- This also has a large outer diameter to form a stable stop.
- the seal in the bottom region of the piston however, has a smaller outer diameter, whereby the projected areas are unequal. This has the consequence that in addition acts in the closing direction, resulting force, the holding the piston in the closed position.
- the disadvantage of this is that when opening the valve, the solenoid must generate a correspondingly large magnetic force in order to additionally overcome the re sulting force. As a result, such a valve requires a large-sized solenoid, which must be supplied with a corresponding current.
- the invention is therefore an object of the invention to provide a valve which requires a lower power consumption when opening and closing.
- the cooperating with the valve seat seal has an outer diameter which corresponds approximately to the outer diameter of the seal or the stop at the open end of the piston.
- the resulting force is zero.
- the dimensions of both outer diameters differ slightly, preferably maximally 5% and in particular maximally 3%. The result The resulting resulting force is negligible with respect to the magnetic force of the solenoid.
- the seal in the bottom area has a smaller outer diameter than the seal at the open end. Since the sealing lip of the seal rests against the housing of the valve at the open end of the piston in the assembled state, its outer diameter is already reduced in the installed position and thereby approaches the outer diameter of the seal in the bottom region of the piston by the mounting.
- a good media resistance of the seal is given with the use of rubber, preferably a fluorine rubber as sealing material. Another advantage is that such a rubber seal is temperature resistant up to 180 ° C.
- a reliable connection of the seals or the stop with the piston is advantageously achieved when the rubber is vulcanized.
- the valve can be manufactured with a low weight if the seal cooperating with the valve seat and the seal or stop at the open end of the piston are separate components.
- valve seat cooperating with the seal and the seal or the stopper at the open end of the piston are mounted as a coating on the piston.
- the advantage is that the coating can be made separately and then mounted on the piston.
- the outer diameter of the seal has an axial height of 10% to 50% of the piston height.
- the thickness of the seal or the stopper at the open end of the piston is 0.4 mm to 1 mm, preferably 0.5 mm to 0.8 mm.
- the housing part cooperates in the closing direction of the valve with the housing or a Ge.
- the stop may be formed in the manner of a sealing lip radially outward and in the direction of the solenoid. An angle of 45 ° to 60 ° has proved to be advantageous here. In this case, the stop acts as a seal.
- the stop additionally has a cylindrical abutment surface. This can be used as a stop during the movement of the piston in the open position. In this way, a stop for the two movement directions of the piston is created with only one component and little effort ever.
- a greater resistance to aggressive media and thus a longer life are given when the piston is made of stainless steel, preferably a chrome-nickel steel Metal piston also has the advantage of a higher temperature resistance, so that the valve according to the invention can cover a wider field of application, especially at higher temperatures.
- the wall thickness of the piston can be made significantly smaller.
- the metal of the piston has a thickness of 0.3 mm to 1 mm, preferably from 0.4 mm to 0.8 mm and in particular of 0.5 mm.
- the piston can according to a further advantageous Substituted staltung, particularly inexpensive to produce in one step, when the piston is a deep-drawn part.
- the piston from plastic and to form the stop and the seal as a one-piece coating over the piston.
- FIG. 1 is a sectional view of a valve according to the prior art
- Fig. 2 is an enlarged sectional view of the inventions
- Fig. 3 is an enlarged view of a piston.
- Figure 1 shows the valve comprising a housing 1.
- the housing 1 further has a molded flange 3, via which the housing 1 is flanged to a turbocharger, not shown, in the region of the By pass line 4.
- a solenoid 5 with a coil 6 and a metal pin 7 is arranged in the housing 1.
- the Metal pin 7 is connected to a cup-shaped piston 8, which has a seal 10 at the periphery of its bottom 9.
- the seal 10 is located on the Ven tilsitz 11 to close the bypass line 4, so that no medium can flow from the line 4 into the conduit 12.
- a spring 7a presses the piston 8 in the direction of the valve seat 11.
- a further seal 13 with a sealing lip 14 is arranged. If the solenoid 5 is energized, a magnetic force acts on the armature 2, whereby the piston 8 is moved in the direction of the housing 1.
- the sealing lip 14 seals the piston 8 against the housing 1 from.
- the metallic piston 8 in Figure 2 has a stop 13 at the open end of the piston 8 and a seal 10 in the bottom region of the piston 8.
- the stop 13 extends at an angle of 45 ° radially outward and in the direction of the solenoid 5 and has a Thickness of 0.8mm. In the closing direction of the valve, the stop 13 moves against a housing part 15 and seals the piston 8 there against the housing 1.
- Radially inside, the stopper 13 has a cylindrical abutment surface 16 which cooperates with the movement of the piston in the open position with a correspondingly formed surface of the housing 1 and thus limits the further movement of the piston 8.
- Seal 10 and stop 13 are made in one piece from fluororubber, this component is mounted as a coating on the piston 8.
- the seal 10 has an outer diameter which corresponds approximately to the outer diameter of the stop 13, or is slightly smaller. A resultant resultant force is negligible with respect to the magnetic force generated by the solenoid.
- the outer diameter of the seal 10 is constant over an axial height of 40% of the piston height. In the further axial course of the outer diameter of the coating decreases in the form of a slope 17 to about 1mm thickness. With this thickness, the coating at the open end of the piston 8 in the stop 13 on.
- the piston 8 in Figure 3 is made of plastic with a coating of elastomer, which forms the stop 13 and the seal 10.
- the piston 8 corresponds to the basic construction of the piston in Fig. 2. The difference is that the elastomeric coating has a nearly constant thickness. The enlargement of the outer diameter in the region of the seal 10 is achieved by a correspondingly greater wall thickness of the plastic piston 8 in this area.
