A compressor module for a refrigerant circuit of a motor vehicle air-conditioning system, exhibiting a modular multi-part housing with a low-pressure refrigerant inlet, a high-pressure refrigerant outlet and a compressor, characterized in that an inner heat exchanger of the refrigerant circuit is produced such that it is integrated into the compressor module, wherein the housing of the compressor module fully encloses the inner heat exchanger.

Compressor module

A heat pump system for a motor vehicle comprises at least two heat exchangers, through which, for heating and/or cooling the motor vehicle interior, a flow is conducted, and at least two coolant circulationsseparable from one another, of which at least one is connectable, independently of the other coolant circulation, with one, two or more heat exchangerssuch that through these, in the presence of a connection with two or more heat exchangers, a flow is successively conducted and the other coolant circulation is connectable with at least one heat exchanger

Device for distributing the coolant in an air-conditioning system of a motor vehicle

A device for compression of a gaseous fluid, in particular of a refrigerant. The device comprises a housing with a suction pressure chamber and a high pressure chamber, a compression mechanism as well as a configuration developed in the proximity of the high pressure chamber, for the separation of a control mass flow from a fluid-lubricant mixture for the control of the compression mechanism. The configuration is developed and disposed with a first flow duct for diverting a main mass flow of the compressed fluid-lubricant mixture from the device and a second flow duct for conducting the control mass flow within the device to the suction pressure chamber in such manner as to separate a mass flow of the gaseous fluid as a control mass flow. A method for the separation of a control mass flow is also provided.

Compression device and control mass flow separation method

Control flowrate regulating valve for a scroll compressor inside a vehicle air conditioner or a heat pump, the valve at least comprising: a housing; a closing member; and fluid connection parts for a control flowrate of back pressure, high pressure and suction pressure. Fluid connection parts having effective areas, of the closing member, assigned to the fluid connection parts. Control flowrate regulating valve has a fluid connection part, for peripheral pressure, and an effective area of the closing member. It is formed in a fluid-sealing manner for other chambers having high pressure, back pressure and suction pressure, such that the force, obtained from the pressures applied to the closing member, is applied to the closing member to allow the control flowrate, which moves from the high pressure to the suction pressure, to flow in a manner of forming the back pressure. Peripheral pressure is applied to the closing member.
