The invention relates to a device for driving a compressor of a vaporous fluid, particularly an electric motor. The device has a rotor and a stator, which are extended along a common longitudinal axis, as well as an insulation element. The insulation element is designed as a single part and connected with a stator core of the stator in a form-fitting manner such that the stator core and the insulation element form an integral and single-part component of the stator. The invention further relates to a method for producing a stator of the device, particularly the stator core with the insulation element.

A rotary cylinder piston compressor pump is provided, including a rotating shaft (2), a piston (3) and a cylinder (4). A rotating shaft hole (21) is provided in the rotating shaft (2). An oil guiding channel, provided in the cylinder (4), communicating with the rotating shaft hole (21). A recess (45) is formed in the inner end face of the cylinder (4). An oil path (61) sealed relative to a compression cavity (49) of the cylinder (4) is formed between the recess (45) and the piston (3). The oil path (61) between the recess (45) and the piston (3) is communicated with an oil path (62) between the piston (3) and the rotating shaft (2) and is communicated with the oil guiding channel by means of an oil returning channel. Also provided is a compressor including the compressor pump.

A pressurization dehydrator comprising an air compressor and a controller connected to enable automatic operation of the dehydrator. The dehydrator is implemented as a freestanding, bench-top unit having a housing that encloses a baffle plate on which the compressor is mounted. The bottom panel of the housing is affixed to the plate using dumpers inserted therebetween. The plate has legs protruding through the corresponding openings in the bottom panel for supporting the whole unit in the upright position on the bench top. Some or all of the legs may not have contact with edges of the openings. In operation, the legs provide an efficient mechanical pathway for transferring some vibrational energy of the plate to the bench top, thereby diverting said energy away from the housing. The circuit board of the controller is affixed to the housing, which beneficially reduces vibration levels transferred to the electronic components of the controller.

A power converter includes: a converter including four switching elements in full bridge configuration, the converter converting alternating-current power supplied from an alternating-current power supply into direct-current power; a reactor provided between the alternating-current power supply and the converter; a smoothing capacitor connected between direct-current terminals of the converter; an alternating-current voltage detector detecting an alternating-current voltage output from the alternating-current power supply; an alternating current detector detecting a current flowing through the reactor; and a control circuitry controlling a switching operation of the switching elements. The control circuitry controls the switching elements such that a potential fluctuation due to the switching operation is reduced between a P terminal of the converter and an L terminal of the alternating-current power supply, or between a G terminal of the converter and an N terminal of the alternating-current power supply.

A vehicular electric compressor (1) includes a compressor body (2) that compresses fluid sucked from outside and then discharges the fluid, using electric power as power, a protective component (4) attached on the compressor body (2), and an external attachment leg (3) attached to the compressor body (2) through the protective component (4). The protective component (4) is lower in strength than the external attachment leg (3).
