RECIPROCATING COMPRESSOR |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a reciprocating compressor with a piston, which is compact and having high sealing performance. <P>SOLUTION: The reciprocating compressor includes: a low-pressure compressor unit having a low-pressure piston and a low-pressure cylinder for compressing air with the low-pressure piston reciprocating while oscillating within the low-pressure cylinder; a high pressure compressor unit having a high pressure piston and a high pressure cylinder for further compressing the air compressed in the low-pressure compressor unit with the high pressure piston reciprocating while oscillating within the high pressure cylinder; and a motor for driving the low-pressure compressor unit and the high pressure compressor unit. A maximum tilt angle during oscillation of the low-pressure piston is made larger than a maximum tilt angle during oscillation of the high pressure piston. <P>COPYRIGHT: (C)2012,JPO&INPIT |
