A magnetically coupled piston pump includes a piston, a pump body, and a set of drive magnets. The piston includes a set of piston magnets. Each piston magnet has poles arranged along a longitudinal axis of the piston, and each piston magnet is arranged in the piston so that the orientation of the poles of each piston magnet is the opposite of the orientation of each adjacent piston magnet. The piston is disposed in and permitted to move within the pump body. The set of drive magnets is arranged outside the pump body. Each drive magnet corresponds to a piston magnet, has poles arranged along the longitudinal axis, and is arranged so that the orientation of the poles is opposite the orientation of the poles of the corresponding piston magnet. A drive unit is coupled to the drive magnets for moving the drive magnets along the longitudinal axis.

A scroll device includes a fixed scroll with a first involute and a first cooling chamber; an orbiting scroll with a second involute and a second cooling chamber, the orbiting scroll mounted to the fixed scroll via a mechanical coupling, the orbiting scroll configured to orbit relative to the fixed scroll around an orbital axis; a flexible conduit in fluid communication with the first cooling chamber and the second cooling chamber, the flexible conduit extending around the orbital axis from a first side of the scroll device to a second side of the scroll device; and an integrated aftercooler.

This disclosure relates to refrigerant compressors, and, in particular, relates to cooling for the power electronics of such compressors. An example refrigerant system includes a main refrigerant loop in communication with a condenser, an evaporator, and a compressor. The refrigerant system further includes at least one cooling line configured to direct refrigerant from the main refrigerant loop to cool a chamber containing electronic components. A method is also disclosed.

A preheating heat exchanger allows heat exchange between cooling water on an outlet side of an auxiliary cooling heat exchanger and supply water that has passed through a preheating bypass path.

The present disclosure relates to and envisages a compressed air generation system. The compressed air generation system includes a multistage reciprocating compressor for providing compressed air at a high pressure. A combi-cooler assembly includes a pair of intercoolers and a radiator assembly is configured to dissipate heat recovered by the cooling fluid from first reciprocating compression stage, second reciprocating compression stage, third reciprocating compression stage and crankcase assembly of the radiator circuit. The system is a stand-alone unit.
