Title:
DUAL CYLINDER REFRIGERANT COMPRESSOR WITH MUFFLER
Document Type and Number:
Japanese Patent JPS5724468
Kind Code:
A
Abstract:
A multicylinder refrigerant compressor is disclosed having double-ended pistons operating in aligned cylinder bores of a cylinder block to discharge refrigerant from the opposite ends thereof to discharge chambers formed in opposite ends of the compressor. A muffler arrangement is completely formed within the compressor and comprises a separate attenuation chamber ported at one of two opposing ends thereof directly to each discharge chamber. Each attenuation chamber is formed within and as an integral part of the cylinder block between two adjacent cylinder walls thereof and an elongated attenuation passage directly connects the attenuation chambers at their other end. The attenuation passage is also formed in and as an integral part of the cylinder block and extends between the two aforesaid adjacent cylinder walls. The volumes of the attenuation chambers are substantially equal and the length of the attenuation passage is substantially longer than the corresponding longitudinal dimension of the attenuation chambers so as to attenuate the refrigerant discharge pulses admitted to the discharge chambers to an acceptable output level totally within the structure of the compressor.
