Compressor used in motor vehicle, has cylinder whose cylinder bore is connectable with atmospheric pressure by decompression channel whose opening leads to cylinder bearing surface is arranged in region of bottom dead center

摘要

The compressor (1) has crankshaft housing (6) having air inlet and cylinder head (9) with exhaust valve and piston. The piston has piston head rigidly connected with connecting rod. A piston head portion is movable from bottom dead center (BDC) to upper dead center (UDC) under full guide of piston stroke and under angle change of position of piston head portion in cylinder bore. The cylinder bore is connectable with atmospheric pressure by decompression channel whose opening leads to cylinder bearing surface is arranged in region of BDC.
