A previously developed reciprocating air microcompressor having a 1-mm(0.04 in)-diameter piston, an inlet port that did not have a moving valve, and an outlet port equipped with a miniature reed valve, was capable of a maximum discharge pressure of 80 kPa (gage, 11.6 psig) at a piston frequency of 100 Hz. We have improved on this compressor performance, and have attained a maximum discharge pre...

The equations of motion of plate type suction and discharge valves mounted on reciprocating pistons are given. Their solutions by modal series expansion are discussed and finally given in a form that conforms to the notation and approach used in previous work. Using the definition of an equivalent pressure, it is shown that both types of valves are assisted in closing, which may result in prema...

In the article, mechanical and electromechanical starting characteristics of an asynchronous electric drive a two-piston ship compressor are investigated by numerical method. A distinctive feature operation reciprocating is that its load torque changes with certain frequency. The dependence on shaft piston angle rotation presented in form Fourier series. Moments inertia reduced to single system...

Gas leakage is one of the main sources inefficiencies in low-capacity reciprocating compressors, undermining compressor performance by reducing mass flow rate and increasing energy consumption. In piston–cylinder clearance driven piston motion pressure difference between compression chamber internal environment shell. This paper reports a parametric numerical analysis compressor. A simulation m...
