A vacuum system is disclosed. The vacuum system includes a first pump bay and a second pump bay enclosed by an enclosure. Each pump bay houses a motor and a vacuum pump driven by the motor. An inlet manifold and an exhaust manifold are in fluid communication with the first and second pump bays. The inlet manifold and the exhaust manifold are arranged to flow air through the pump bays to cool at least the vacuum pumps.

An oil-lubricated slide vane rotary vacuum pump with a slide vane unit, and with an oil separating and reconditioning device, wherein oil and gas are separated by separating devices, possibly complemented by oil coolers and/or oil pumps. One or more monitoring and/or servicing devices are provided, and the oil separating and reconditioning device is installed in an oil separating and reconditioning housing. Side walls extend transversely to a plane of rotation of a slide vane rotor, and define a longitudinal extent of the oil separating and reconditioning housing. The one or more monitoring and/or servicing devices are arranged only in one or more cover parts which are attached to one or both end walls of the oil separating and reconditioning housing. The oil separating and reconditioning housing is formed with the side walls, the bottom wall and the top wall without being configured for a monitoring and/or servicing device.

A mounting structure of a compressor for a refrigerator that includes: a base on which the compressor is mounted; a compressor that includes: a main body, and an ear mount that is coupled to the main body and that is configured to mount on the base; a post that is coupled to the base, that extends upwardly from the base, and that is configured to couple to the ear mount; a vibration absorber that is interposed between the ear mount and the base and that is configured to absorb vibration of the compressor; a stopper that is configured to restrict the ear mount from departing from the post; and an inner ear mount that includes a hole that is open toward a first direction, wherein the compressor is inserted into the machine room in the first direction, is disclosed.

A system includes a compressor and a mounting apparatus for mounting the compressor. The compressor is held exclusively by way of the mounting apparatus. The mounting apparatus includes two pendulum-type bearings and a hinged support.

A heat exchanger for changing a temperature of a pumped gas flow and a pump comprising the heat exchanger is disclosed. The heat exchanger comprises: at least one tube configured to contain a flow of fluid; said at least one tube being at least partially embedded within a block of material; wherein said heat exchanger comprises mounting means configured to mount said heat exchanger adjacent to a gas port of a pump such that a least a portion of said heat exchanger extends into a path for gas flow flowing through said gas port; wherein the mounting means comprises a flange, the flange being configured to connect with the gas port of the pump, the block being mounted to the flange such that the block extends towards the rotor of the pump when the flange is connected with the gas port of the pump.

The invention relates to an eccentric screw pump, comprising at least one stator (1) composed of an elastic material and a rotor (2) that can be rotated in the stator (1), the stator (1) being surrounded by a stator casing (3) at least in some regions. The stator casing (3) consists of at least two casing segments (19) as a longitudinally divided casing and forms a stator clamping device, by means of which the stator (2) can be clamped against the rotor (1) in the radial direction. The pump is characterized in that the casing segments (19) have at least one clamping flange (20) having first clamping surfaces (21) at each end of the casing segments and that one or more clamping elements (22, 23), which can be displaced in the axial direction and have second clamping surfaces (24), are placed onto the clamping flange (20), the first clamping surfaces (21) and the second clamping surfaces (24) being designed in such a way and interacting in such a way that the stator casing (3) can be clamped against the stator in the radial direction in the course of an axial displacement of the clamping elements (22, 23).

An engine assembly has an engine core comprising at least two stacks of rotary internal combustion engines drivingly connected to a common load. The engine further comprises a compressor section having an outlet in fluid communication with an inlet of the engine core, and a turbine section having an inlet in fluid communication with an outlet of the engine core.

A screw compressor for a heating, ventilation, and air conditioning (HVAC) system. The screw compressor includes a housing having an inlet end and an outlet end for refrigerant to pass into and out of the housing. A motor is within the housing. A plurality of screw sets are arranged about the motor. The screw sets receive refrigerant entering through the inlet, compress the refrigerant between meshed rotors of the plurality of screw sets, and direct refrigerant out of the housing through the outlet end of the housing.

A motor-operated compressor according to the present disclosure includes a first scroll performing an orbiting motion, a second scroll coupled to the first scroll to form a compression chamber with the first scroll and radially supporting a rotation shaft, a main housing coupled to the second scroll outside the second scroll, and coupled with a driving motor to form a motor chamber, the main housing including an opened end at one side of the motor chamber, a frame portion formed at another side of the motor chamber to axially support the second scroll, and a first bearing portion formed through the frame portion so that the rotation shaft is inserted therethrough to be radially supported, and an inverter housing coupled to the opened end of the main housing to seal the motor chamber, whereby a main frame can be easily formed and a compressor fabrication process can be simplified.

A screw compressor for a utility vehicle includes at least one housing, at least one housing cover and at least one rotor housing. At least one seal is provided, wherein, when assembled, there is an oil sump in the housing, and the seal is arranged between the housing cover and the rotor housing and projects out of the oil sump with respect to the assembled state. The seal is formed as a sealing plate and has multiple passage openings.
