Patent number: 11262113Abstract: 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.Type: GrantFiled: July 7, 2017Date of Patent: March 1, 2022Assignee: Hanon SystemsInventors: Philipp Kozalla, Roman Heckt

Patent number: 11047383Abstract: 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.Type: GrantFiled: March 21, 2017Date of Patent: June 29, 2021Assignee: Hanon SystemsInventors: Roman Heckt, Philipp Kozalla, Laura Arriazu, Bernd Vierkotten
