Embodiment Construction

[0016] figure 1 The valve is shown, including the housing 1 . Furthermore, the housing 1 has a molded flange 3 , via which the housing 1 is flanged to a turbocharger (not shown) in the region of the bypass line 4 . A solenoid 5 with a coil 6 and a metal rod 7 is arranged in the housing 1 . The metal rod 7 is connected to a pot-shaped piston 8 which has a seal 10 on the circumference of its base 9 . In this case, the spring 7a presses the piston 8 in the direction of the valve seat. The housing 1 also has a cylindrical section 11 which extends in the direction of the piston 8 . A cylindrical bushing 12 connected to the housing 1 surrounds the cylindrical section 11 . The cylindrical bush 12 has a radially inwardly facing flange 13 on which a V-shaped seal 14 is placed. The ends of the cylindrical section 11 hold the seal 14 in place. The inner wings of the seal 14 seal the piston relative to the housing 1 . If the solenoid 5 is energized, a magnetic force acts on the arm...

Abstract

The invention relates to a valve comprising a housing (1), a solenoid (5) arranged in the housing (1), a pin (7) that can be moved by the solenoid (5), a cup-shaped piston (8) that is connected to thepin (7), and a seal (14) which is arranged in the housing (1) for sealing the piston (8) against the housing (1). The seal (14) is a disk having a radially internal sealing surface (15), which is clamped at the radially outer edge in the housing (12, 11).

Description

technical field [0001] The invention relates to a valve, comprising: a housing; a solenoid arranged in the housing; a rod movable by the solenoid; a pot-shaped piston connected to the rod; Housing seal seals. Background technique [0002] Such valves are used primarily as air steering valves on turbochargers in motor vehicles in order to open a bypass to the intake side during freewheeling and are therefore known. In order to prevent excessive braking of the turbocharger, but also to ensure a fast start-up, fast opening and closing of the valve is an important prerequisite. It is especially important when closing that an immediate closure is achieved by placing the piston on the valve seat. The valve seat is formed by the housing of the turbocharger, to which the valve is flanged. In this case, the axially displaceable piston is sealed relative to the housing. Sealing is achieved by seals. Such seals generally have a V-shaped cross section, wherein the wings of the "V" ...
