embodiment

[0016]As shown in FIG. 1, a compressor with a transmission (hereinafter, simply referred to as a compressor) includes a scroll type compression mechanism 20 to which a transmission mechanism 30 and a control mechanism 40 are integrally combined. The compressor is mounted on, for example, a vehicle and forms a part of an air conditioning system. In FIGS. 1 to 3, the left side, that is, the position at which an input shaft 1 is located is defined as the front side, and the right side, that is, the position at which an output shaft 2 is located is defined as the rear side.

[0017]The compressor includes a housing 10, which is formed by integrally fastening a first housing member 3, a second housing member 4, a third housing member 5, and a fourth housing member 6 in that order. The rear end face of the first housing member 3 and the front end face of the second housing member 4 engage with and are fastened to each other to form a transmission chamber 10a. The transmission chamber 10a is ...

Abstract

A compressor with a transmission includes a clutch that varies the rotational speed of an output shaft between two different speeds. The clutch includes a friction layer, which secures a ring roller by movement of the ring roller in a first direction (securing direction), a first control chamber, a first control piston accommodated in the first control chamber and movable in the direction of an input shaft axis, a first thrust bearing between the first control piston and the ring roller, a second control chamber facing the first control chamber, a second control piston accommodated in the second control chamber and movable in the direction of the axis), a second thrust bearing between the second control piston and the ring roller, and a pressure control mechanism, which controls a first control pressure supplied to the first control chamber and a second control pressure supplied to the second control chamber.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a compressor with a transmission.[0002]Japanese Laid-Open Patent Publication No. 2007-107412 discloses a conventional compressor with a transmission. The compressor with a transmission includes a housing, a compression mechanism, an input shaft, an output shaft, a transmission mechanism, and a control mechanism. The compression mechanism is provided in the housing and compresses refrigerant. The input shaft extends into the housing from the outside of the housing and is supported to be rotational about the axis. The output shaft extends in the housing and is supported to be rotational about the axis to drive the compression mechanism. The transmission mechanism is provided inside the housing between the input shaft and the output shaft. Also, the transmission mechanism drives the compression mechanism at different speeds by transmitting torque of the input shaft to the output shaft and also by selectively increasing a...
