An apparatus comprising a stator and a rotor which are arranged inside a housing extending along a common longitudinal axis, wherein the stator encloses the rotor in a radial direction. A space is formed between an inside of a wall of the housing and an outside of a wall of the stator. The housing has a first housing element and a second housing element that are arranged with their contact surfaces aligned with each other thus sealing the housing. Thereby, a sealing element is arranged between the contact surfaces of the housing elements. The sealing element has the shape of an annular disc with a circumferential form and at least one sealing area. In the circumferential direction, the form corresponds to a contour of the contact surfaces. The sealing area is designed to at least partially enclose the space.

Compressor sealing element arrangement near stator for controlling gaseous fluid flow there through

A device for compressing a gaseous fluid from a low-pressure section into a high-pressure section. The device has a housing with a housing member, a compression mechanism arranged between the low-pressure section and the high-pressure section as well as a flow duct connecting the high-pressure section to the low-pressure section. The housing member is configured with a high-pressure-side port and an oil separator. An outlet opening of the port and an oil outlet are configured at diametrical ends of the oil separator. The oil outlet is arranged in the lowermost section of the oil separator in a direction of the effect of gravity and is hydraulically connected to an inlet of the flow duct. The housing member is configured with the inlet chamber such that the high-pressure-side port is able to be arranged with the axis within the inlet chamber irrespective of the arrangement of the oil outlet.

Device for compressing a gaseous fluid

A scroll compressor for refrigerant-oil mixtures with oil return, including a housing element and a fixed scroll, wherein the housing element is connected to the fixed scroll by means of a seal in such a way that an outlet chamber is formed between the housing element and the fixed scroll, wherein, for oil separation and oil return purposes, an oil separation chamber, which has a high-pressure refrigerant outlet and an oil collection area, and an oil return channel towards a suction pressure chamber are arranged downstream of the outlet chamber, the scroll compressor being characterized in that an outlet chamber drain for draining oil into the oil return channel of the oil separation chamber is formed in the geodetic lower region of the outlet chamber.

Scroll compressor for refrigerant-oil mixtures with oil return

A scroll compressor for compressing a gaseous fluid, in particular a refrigerant. The scroll compressor exhibits a non-moving stator with at least one outlet and a moving orbiter, each with a base plate and a spiral-shaped wall that extends from the base plate. The base plates are arranged relative to one another in such a way that the walls interlock with one another and closed working chambers are created. The volumes and the positions of the working chambers are changed in reaction to a rotary movement of the orbiter here.

Scroll compressor and process for compressing a gaseous fluid with the scroll compressor

A fixed scroll for a scroll compressor includes a plurality of pillar portions extending axially from a first face of the fixed scroll to an opposing second face thereof. Each of the plurality of the pillar portions is spaced radially outwardly of a spiral structure at least partially defining a compression chamber of the scroll compressor. The fixed scroll further includes an annular array of spaced flow openings into the compression chamber of the scroll compressor with each of the flow openings formed between adjacent ones of the pillar portions.

Scroll compressor having internal fixed scroll with pillar design

A scroll compressor with oil return unit, having a fixed spiral and an orbiting spiral, which compresses gas from a suction-pressure chamber into a high-pressure chamber. A counter-pressure chamber is connected to the orbiting spiral and the orbiting spiral presses onto the fixed spiral. The oil return unit has a counter-pressure spiral nozzle having a high-pressure channel connected to an end face for oil supply. A suction-pressure spiral nozzle with a suction-pressure channel connected to the end face discharges oil into the suction-pressure chamber. A counter-pressure channel is arranged between the counter-pressure spiral nozzle and the suction-pressure spiral nozzle for discharging oil into the counter-pressure chamber.

Spiral compressor with oil recirculation unit

A motor housing for a compressor, having a cylindrical, internally pressurized part for receiving the electric motor, which, at the compressor side, is securable on a central housing member of the compressor and, at the head side, is closed by a bottom whose outer side serves as a contact area for an inverter for driving the motor, wherein on the inner side of the bottom a flow path for cold suction gas and on the outer side of the bottom cooling areas for the absorption of heat loss generated by the inverter are developed. An assembly having a motor housing, an inverter and an electric motor are also provided.

Motor housing for an electric compressor of an air conditioning system

A device for control of the air flow rates into the instrument panel air outlets of a vehicle heating or air conditioning unit is described that is provided with a casing, with damper doors for both instrument panel side air outlets in the casing parts and at least one damper door for the instrument panel central air outlet in the casing part, whereby the damper doors are pivotably supported on one common shaft. Exactly one closing position is assigned to the damper doors in the first casing part, whereas several closing positions are assigned to the damper door in the second casing part continuously over a pivoting range of the shaft, whereby the closing position of the damper doors is arranged in the pivoting range of the damper door. This device enables separation and independent control of the air flow rates.
