The switch device is arranged within a terminal box mounted on the unit housing. The lever is seated within a switch housing which is incorporated in a cartridge-like manner into the pump housing and which is hermetically sealed to the outside and which is arranged neighbouring the terminal box that such it is only in magnetic active connection so that the reed contact located in the terminal box is controlled by the magnet located in the switch housing. In this manner a usual terminal box may be used which does not need to be sealed with respect to the delivery flow.

Abstract: A scroll compressor includes a first scroll member and a second scroll member with intermediate spiral wraps. A drive member causes the scroll member to orbit relative to one another to create pockets of progressively changing volume between a discharge pressure zone and a suction pressure zone. One of the scroll members defines a chamber which contains fluid, a pressure intermediate the discharge pressure and suction pressure of the compressor. A temperature responsive valve is located within the chamber to release the intermediate pressure fluid to the suction pressure zone of the compressor when an excessive temperature is sensed.

Abstract: A scroll type compressor has both a high pressure lubricant sump and a low pressure lubricant sump. Lubricant from the low pressure lubricant sump is supplied to the various bearings, thrust surfaces and other moving components of the compressor. It is then rested in such a way that it can absorb heat from the motor windings thus maintaining the operating temperature of the motor. Lubricant from the high pressure sump is supplied to the moving compression chambers defined by the scrolls at a point intermediate suction and discharge. The lubricant supplied from the high pressure sump is first cooled and then used to cool the low pressure sump prior to being supplied to the moving compression chambers. The compressed gas is routed through two lubricant separators and a gas cooler prior to being supplied for its intended use.

A clutch is attached to the front of the compression mechanism, and the motor is attached to the rear of the compression mechanism. The motor has an output shaft connected to the drive shaft. The clutch selectively transmits power from the engine to the drive shaft. This structure makes the hybrid compressor compact and reduces the imbalance of the load applied to its drive shaft.
