An automotive air conditioning system equipped with an electrical compressor uses a single-shaft, dual output generator to provide a low voltage output to drive existing 12-V or 24-V automotive electrical equipment and a high voltage output to drive the air conditioning motor-driven compressor, and a control device to control the electrical compressor.

Automotive air conditioning apparatus

A sliding vane type rotary compressor having a rotor, at least one vane slidably mounted on the rotor, a cylinder accomodating the rotor and the vane, and end plates fixed to both ends of the cylinder so as to close vane chambers defined by the vane, the rotor and the cylinder at both sides of the vane chamber. The improvement comprises that the compressor is constructed to meet the following condition:

Sliding vane type rotary compressor

A rotary compressor comprises an open-ended cylinder having its open ends closed by end plates and an eccentrically rotatable rotor housed inside the cylinder. A hydrodynamic seal is provided on either the rotor or each of the end plates for minimizing any possible unwanted leakage of lubricant oil.

Rotary compressor

An improved vane type rotary compressor provided with a control mechanism of a lubricating oil supply passage by which the lubricating oil supply passage is arranged to be opened during operation of the compressor, and to be closed during shut-down of the compressor for obtaining a sufficient amount of lubricating oil supply during operation and also for preventing reverse rotation during shut-down of the compressor.

Rotary vane compressor with valve control of oil to bias the vanes

Oil compositions are disclosed for effective use in the lubrication of rotary-type compressor for refrigeration equipment. The composition essentially comprises a polyglycol oil blended with specified amounts of at least one of additives or compounds of the group consisting of glycidyl ether type epoxy compounds, epoxidized fatty acid monoesters and epoxidized vegetable oils.
