Claims (1)

  1. 토출실과 크랭크실 사이를 잇는 토출압력의 공급통로에 개재시켜서 제1제어밸브를 설치하고, 그 제1제어밸브는 흡입압력이 설정압력을 상회하는 상태에서는 상기통로를 닫고 흡입압력이 설정압력을 하회하는 상태에서는 그 공급통로를 열도록 설치하는 한편, 상기 크랭크실과 흡입챔버내에 연통시켜서 가스에 의한 블로우바이 가스의 탈기통로를 설치하는 동시에 그 탈기통로에 개재시켜 제2제어밸브를 설치하고, 그 제2제어밸브는 토출압력이 설정압력을 상회하는 상태에 있어서는 상기 탈기통로를 열고, 그 토출압력이 설정압력을 하회하는 상태에 있어서 그 탈기통로를 닫도록 설치하여 이루어지는 요동사판형 압축기에 있어서의 크랭크실 압력 제어 기구.
