Definitions

  • the invention relates to a valve with a housing, a solenoid disposed in the housing, consisting of ei ⁇ ner coil, a movably arranged magnet, in the center of a pin is arranged and at one end of a piston is fixed, wherein the Magnet is surrounded by a cylindrical sleeve acting as a guide such that the cylindrical sleeve between the coil and magnet is arranged.
  • 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.
  • a quick start to ensure a rapid opening and closing of the valve is an essential prerequisite che.
  • when closing it depends on the immediate closing 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. This has the consequence that the valve seat is not completely parallel to the piston, which would be required for a quick and especially tight closing, which is why additional sealing elements are provided.
  • the temperature in the valve increases, the temperature of the sealing elements increases, increasing the friction force on opening or closing.
  • the rising temperature in the solenoid also causes the magnetic force generated by the solenoid to drop.
  • the opening time could be shortened again.
  • larger components require more construction ⁇ space and have higher costs.
  • the invention is therefore based on the object to provide a valve of the type mentioned, which fast opening times light enables even with hö ⁇ heren operating temperatures.
  • the valve is intended to claim no additional space be ⁇ and be inexpensive.
  • the cylindrical sleeve has a chamfer at its end facing the coil on its outer side.
  • the provision of the chamfer on the cylindrical sleeve leads to an approximately 10% increase in the magnetic force, which allows a faster opening of the valve, even at high operating temperatures.
  • the cost of the modified sleeve is low.
  • a significant advantage is also that the valve according to the invention requires no additional space. Additional components are also not necessary ⁇ Lich, so that no additional expense arises in the assembly.
  • Another advantage is that the gain of the opening force can be adapted specifically widely to appropriate applications and Randbedingun ⁇ gen.
  • the zy ⁇ linderförmige sleeve is arranged with the valve closed to the coil so that the chamfer is completely within the coil.
  • the chamfer in the closed state of the valve in a range of 10% to 40%, preferably in a range of 20% to 30% of the length of the coil , starting from the side of the coil facing the piston.
  • the chamfer is arranged at a distance from the edge region of the coil.
  • Fig. 1 is a sectional view of the valve according to the invention and Fig. 2 is an enlarged view of the valve in the region of the sleeve.
  • the housing 1 shows the valve with a housing 1.
  • the housing 1 further has a molded flange 2, via which the housing 1 is flanged to a turbocharger, not shown, in the region of the bypass line 3.
  • a solenoid 4 with a coil 5 and a metal pin 6 is arranged on ⁇ .
  • the metal pin 6 is connected to a cup-shaped piston 7 made of plastic, which has an axially projecting annular sealing surface 9 on the circumference of its bottom 8. In the closed position shown, the sealing surface 9 rests on the valve seat 10 in order to close the bypass line 3, so that no medium can flow from the line 3 into the line 11.
  • a spring 12 presses the piston 7 in the direction of the valve seat 10.
  • the metal pin 6 is surrounded by a magnet 13, which is guided in a cylindrical sleeve 14.

Abstract

La présente invention concerne une soupape comportant un boîtier 1, un solénoïde 5 disposé dans le boîtier 1, une tige 7 pouvant être déplacée par le solénoïde 5, un piston 8 relié à la tige 7 et un joint d'étanchéité. Le piston 8 possède une surface d'étanchéité annulaire 10. La surface d'enveloppe 14 se raccordant à la surface d'étanchéité 10 est réalisée dans cette zone sous la forme d'un bourrelet 15 et au moins une partie de la surface d'étanchéité 10 a un diamètre qui est supérieur à celui de la surface d'enveloppe cylindrique 14 du piston 8.
