Title:
SILENCER AND COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/008794
Kind Code:
A1
Abstract:
This silencer comprises: first and second expansion portions formed by dividing a space enclosed by a cylinder and the silencer into two spaces by means of a linear solid of revolution or a curved solid of revolution around a crankshaft of a compressor; two linking holes joining the two spaces; a partition plate which partitions the space, from among the two spaces, that is closest to a discharge hole; and four outlets through which a refrigerant is discharged to the outside of the silencer. When projected onto a virtual plane that is parallel to an upper surface of the cylinder and is centered about a crankshaft bearing portion, the linking holes are positioned in the vicinity of a position that is 90° different in direction relative to the position in which the discharge hole connecting the cylinder and the silencer is projected onto the virtual plane. When projected onto the virtual plane, the partition plate is positioned in a position that is 180° different in direction relative to the position in which the discharge hole is projected onto the virtual plane. When projected onto the virtual plane, the outlets are positioned in the vicinity of positions that are 45° different in direction relative to the position in which the linking holes are projected onto the virtual plane.
