Beschreibung
Zusammenfassung:	The present invention is directed to a reciprocating motor pump (1) suitable to generate compressed gas with a reduced noise level of at most 55 dB, wherein said pump (1) includes a pump casing comprising:-a gas inlet nozzle (3);-a gas chamber;-a cylinder chamber (4) comprising a piston (5);-an inlet valve (7);-an outlet valve (8); and-a gas outlet port (9); wherein gas enters the gas chamber (2) through a gas inlet nozzle-(3) of said gas chamber (2) and then flows from said gas chamber (2) to said cylinder chamber (2) to said cylinder chamber (4) through an inlet valve (7) of said cylinder chamber (4), whereby the ratio of the diameter of the opening of the gas passage of said inlet nozzle (3) to the diameter of the opening of the gas passage of said inlet valve (7) is 1:15 to 1:5.
