Abstract

"COMPRESSOR DE PISTãO". Onde um anel de vedação é provido entre um bloco de cilindros e uma placa de válvulas. Ao prover um orifício de passagem em uma posição próxima ao centro do anel de vedação, o momento fletor que age no bloco de cilindros é reduzido, e por causa disto a deformação no bloco de cilindros é restringida. Como resultado, o movimento de reciprocação de um pistão e o movimento rotativo de uma válvula rotatória são realizados suavemente."PISTON COMPRESSOR". Where a sealing ring is provided between a cylinder block and a valve plate. By providing a through hole in a position close to the center of the sealing ring, the bending moment acting on the cylinder block is reduced, and because of this the deformation in the cylinder block is restricted. As a result, reciprocating movement of a piston and rotary movement of a rotary valve are performed smoothly.
