Title:
DOUBLE-ENDED PISTON COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2007/046351
Kind Code:
A1
Abstract:
Use is made of a structure of refrigerant suction into front compression space
(28a) of double-ended piston refrigerant compressor that is different from
that into rear compression space (29a). In particular, the structure of refrigerant
suction into front compression space (28a) consists of suction valve (18a) of
flap valve. On the other hand, the structure of refrigerant suction into rear
compression space (29a) consists of rotary valve (35). Consequently, the pulsation
of compressor can be dampened to thereby suppress any noise generation with the
result that contribution to keeping of quietness can be attained.
