DOUBLE-HEAD PISTON TYPE COMPRESSOR PREVENTING SHORTAGE OF GAS TO BE INTRODUCED TO FRONT COMPRESSION CHAMBER

摘要

PURPOSE: A double-head piston type compressor is provided to suppress gas proceeding to a suction communicating path of a front rotary valve from being introduced to a suction communicating path of a second rotary valve, thereby preventing a shortage of gas to be introduced to a front compression chamber. CONSTITUTION: A first path(57A) communicated with a suction communicating path(48A) of a front rotary valve(50A) and a second path(57B) communicated with a suction communicating path(57B) of a rear rotary valve(50B) are defined in a space(45) of a rotary shaft(31) by a partition(56) extending in an axial line direction. A rear end(56a) of the partition is arranged at the rear of a front end position(P) of a communicating part of the rear suction communicating path of the rear rotary valve and the second path.
