Document Type and Number:
WIPO Patent Application WO/2019/163939
Kind Code:
A1
Abstract:
A recess (37) which is recessed in the direction away from the outer peripheral surface (18c) of a rotor (18) is provided to the inner peripheral surface (14c) of a cylinder (14), and the recess (37) extends such that one-side end of the recess (37) is opened at an end surface (14t) of the cylinder (14). The recess (37) forms a discharge passage through which a refrigerant compressed in a compression chamber (21) is discharged. A discharge lead valve (81) is disposed with the end surface (14t) used as a valve seat so that the discharge passage can be opened/closed. Thus, this vane-type compressor configured so that an enlarged flow path cross-sectional area of the discharge passage can be obtained.
