TH169710A - Negative pressure pump and cylinder head cover - Google Patents

Abstract

A negative pressure pump (10) with a body (20), in which the driven shaft (100) is inserted, and the pump part (30), which creates negative pressure by rotation of the drive shaft, is conveyed to the drive shaft accordingly (40 ) And the drive-side clutch disc (46), which has magnetic properties, can move in the shaft direction of The driven and rotated shaft is the same as the driven shaft. And the drive side clutch disc (48), which transmits rotation from the driven shaft to the driven shaft followed by rotating in one piece with the driven shaft. Along and the driven clutch disc is connected And elastic fasteners (56), which pressures the driven clutch disc against The clutch plate is driven by the coil spring. And electromagnetism (52), which fell off the drive clutch disc This moves from the drive side clutch disc by causing this anti-stick force magnet. And an elongated wall section (38), which is built on the body and accepts the drive-side clutch, through which the working pressure is applied, and the extended wall part (28), which supports the end of the coil spring.

Claims (1)

1. a negative pressure pump which has a body on which the shaft is driven, which is driven, rotated by a driven source. Rotating is placed, inserted into the inside and the pump part, which is molded in the tank, with a moving shaft subjected to negative pressure generation. The rotation of the drive shaft is conveyed to the drive shaft as it and the magnetic drive-side clutch disc is mounted on the drive shaft. It can move in the axle direction of the drive shaft and rotate in one piece as the ketag drive shaft:
