Definitions

  • the invention relates to a valve having a housing, a solenoid arranged in the housing, a pin movable by the solenoid and a cup-shaped piston connected to the pin, the solenoid having at least one coil body, an upper stator arranged in the central opening of the coil body and has a lower stator accommodating the coil former, and the pin is mounted in two bearings, one bearing being arranged in the upper stator and the other bearing being arranged in a bushing.
  • Such valves are used, among other things, as a diverter air valve on the turbocharger in motor vehicles in order to release a bypass to the suction side in overrun operation and are therefore known.
  • a quick opening and closing of the valve is an essential requirement by moving the pin and the piston connected to it into the open position or closed position of the valve.
  • the pen is stored in two bearings. Due to manufacturing and assembly tolerances, the two bearings are coaxial, which leads to increased friction. To compensate for this, a greater magnetic force and a stronger spring for moving the pin is required, which requires larger dimensioned components with a greater consumption of electrical energy. Furthermore, higher magnetic radial forces act on the pin, which can lead to blocking if the valve is operated for a longer period of time.
  • the invention is therefore based on the object of providing a valve which enables the valve to be opened and closed easily.
  • the valve should also be inexpensive.
  • the object is achieved in that a guide sleeve is arranged at least in the central opening of the coil former and the upper stator and the bushing are arranged in the guide sleeve.
  • the valve according to the invention is characterized by the provision of a guide sleeve which receives the upper stator and the socket.
  • the guide bush is a dimensionally stable component, which ensures that the upper stator and the socket are exactly aligned with each other. Since both components each hold a bearing in which the pin is guided, the exact alignment by the guide sleeve allows a particularly smooth movement of the pin to open and close the valve due to reduced friction and reduced radial forces. Blockage of the valve is reliably avoided.
  • the improved mobility of the pin also enables a reduction in the current consumption of the solenoid, as a result of which, in the favorable case, the solenoid and thus the valve can be dimensioned smaller, so that the valve according to the invention requires less installation space.
  • the two bearings achieve a very good dimensional stability of the guide sleeve for exact alignment in that the guide sleeve is made of stainless steel.
  • a particularly firm connection of the guide sleeve with the coil body can be achieved according to a further advantageous embodiment in that the metallic guide sleeve is inserted into an injection molding tool for producing the coil body and is encapsulated with the plastic for the coil body.
  • a valve according to the invention with a reduced weight can be achieved in another advantageous embodiment in that the guide sleeve consists of plastic.
  • Adequate dimensional stability with low weight is achieved in that the guide sleeve has a wall thickness of 0.8 mm to 1.8 mm, in particular of 1 mm to 1.5 mm.
  • the plastic guide sleeve is injection molded onto the coil body of the solenoid, which means that the body is formed in one piece with the coil.
  • FIG. 1 is a sectional view of a valve according to the prior art
  • Fig. 2 shows the housing of a valve according to the invention
  • FIG. 3 shows a second embodiment of the housing according to FIG. 2.
  • FIG. 1 shows the valve, comprising a housing 1.
  • the housing 1 also has an integrally formed flange 3, via which the housing 1 is flanged to a turbocharger (not shown) in the region of a bypass 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 on the circumference of its base 9.
  • a spring 7a presses the piston 8 in the direction of the valve seat 11.
  • the housing 1 also has a cylindrical section 12 which extends in the direction of the piston 8.
  • a cylinder sleeve 13 connected to the housing surrounds the cylindrical section 12.
  • the cylinder liner 13 has a radially inward collar on which a V-shaped seal 14 rests. The end of the cylindrical portion 11 holds the seal 14 in place.
  • the inner leg of the seal 14 seals the piston 8 against the housing 1. 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 seal 14 seals the piston 8 against the housing 1.
  • FIG. 2 shows the housing 2 with the solenoid 5, which consists of the coil 6 and the coil body 15.
  • the coil former 15 is made of plastic and surrounds a guide sleeve 16.
  • the guide sleeve 16 consists of a stainless steel with a wall thickness of 0.8 mm.
  • an upper stator 17 is pressed into the guide sleeve 16 in the upper end and receives a bearing 18 for the pin 7 with a central opening.
  • a bushing 19 is pressed in at the lower end of the guide sleeve 16.
  • the second bearing 20 for the pin 7 is arranged in the socket 19.
  • the guide sleeve 16 ensures that the upper stator 17 and the socket 19 are aligned coaxially with one another without an offset. As a result, the translational movement of the pin 7 is avoided almost without any disruptive forces, due to an inaccurate arrangement and alignment of the bearings 18, 20.
