摘要

PURPOSE:To surely prevent the inflow of a leaked gas into a crank chamber without increasing the number of part items. CONSTITUTION:A continuing passage 2A-2F for connecting each bore 1A-1F to a shaft hole la is formed between the both, and a rotary valve 30 having a suction passage 31 successively allowing the continuing passage 2A-2F of each bore 1A-1F laid in sucking stroke to communicate with a suction chamber 17 is connected to a driving shaft 6 in such a manner as to be synchronously rotatable. The rotary valve 30 has a recovering passage 32 running around the outer circumferential surface near the end surface on a crank chamber 5 side once and communicating with the suction passage 31.
