Title:
RECIPROCATING COMPRESSOR
Document Type and Number:
Japanese Patent JPH1182302
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve volume efficiency by remarkably advance the opening timing of an intake valve so as to increase the intake amount of a refrigerant gas. SOLUTION: Intake valve parts 27d and 28d are formed with a magnetic material, and a magnet M which is approached into intake valve part release holes 3b and 5b when a piston 12 reaches a top dead center is fixed to both end surfaces 12a of the piston 12. When the piston 12 is moved from the top dead center to a bottom dead center, the intake valve parts 27d and 28d are attracted by the magnet M of the piston 12, and intake ports 29d and 30d open before a pressure in a compression chamber becomes lower than that in an intake chamber. As a result, the opening timing of the intake valve parts 27d and 28d advances remarkably, and the intake amount of a refrigerant gas is increased.
