<p>PURPOSE:To improve airtightness between a cylinder block and a vane plate on the surrounding part of an actuating member and obtain high compression efficiency. CONSTITUTION:A spacer 31 constituted of a thick cylindrical base part 32, five pieces of thin plate-like wing pieces 33 radially extended from the base part, and five pieces of press-contacting parts 34 extended forward on the positions formed with respective wing pieces from the base part, is arranged in a suction chamber 18. The press-contacting parts of the spacer opposite to the end face of a cylinder block 1 between the bore 1c and a center hole 1e press a valve plate airtightly by reaction of elastic deformation of respective wing pieces due to interference given between themselves and the blockading end face A of a housing 3.</p> |
