摘要： An interruptible power transmission mechanism couples a drive source to a compressor. The power transmission mechanism has a pulley, which rotates in synchronism with the drive source, and a receiving member, which rotates in synchronism with the compressor. A limit spring couples the pulley and the receiving member such that they rotate together. When the load torque of the compressor exceeds a predetermined value, the diameter of the limit spring is decreased so that the limit spring engages a rib provided on the receiving member. Then, the deformation of the limit spring in the radial direction is locally restricted, causing stress at a specific portion of the limit spring to increase rapidly. As a result, the limit spring is reliably broken at a torque near the desired load torque, thus interrupting power in a desirable manner.

摘要： A vapor jet vacuum pump includes a housing having an inlet port and a foreline conduit, a vapor jet assembly within the housing, a vapor source for supplying a vapor to the vapor jet assembly, and at least one ejector stage. The ejector stage includes an ejector nozzle mounted in the foreline conduit and a fluid inlet located external to the housing and coupled by an ejector conduit to the ejector nozzle. The fluid inlet may be an air inlet for drawing in air at atmospheric pressure. The ejector stage may be driven by a backing pump coupled to the foreline conduit.

摘要： A compressor for an air-conditioning system of a motor vehicle is proposed, which has a controllable compression medium feed mechanism powered by a drive shaft and which, for example, is powered by the combustion engine of the motor vehicle by a belt driven by a drive shaft, where the belt is coupled with the drive shaft of the compressor. The compressor is characterized by the drive wheel (29) having a belt pulley body (31) engaged with the belt (33) and coupled via an elastic coupling element (35) with the drive shaft (7), and by the drive shaft (7) being equipped with a torque limiting mechanism (predetermined fracture point (65)). In the case of another version, it is envisaged that the support mechanism (127) contains a projection (137) protruding from the take-up plate (11) and preferentially forming a single piece with this, as well as a supporting element (139). Furthermore, it is envisaged that the supporting element (139) has a first sliding surface (143) which works in conjunction with a bearing surface (second bearing surface (145)) of the thrust bearing (129), and that the projection (137) and the supporting element (139) fit tightly together via a second sliding surface (147) and/or that the driver (81) and the drive shaft (7) are joined using different materials or are made from a single piece.
