<p>A diaphragm pump (10) comprises a housing (12), a diaphragm element (14) which is provided on the housing (12), and a drivetrain (16) in the housing (12) for reciprocating movement of the diaphragm element (14). The drivetrain (16) has an input drive element (42) and an output drive element (58) connected to the diaphragm element (14). The housing (12) includes a vent (62) at or adjacent to the input drive element (42) of the drivetrain (16), so that, by reciprocation of the diaphragm element (14), air is drawn through and discharged from the vent (62) and, due to the positioning of the vent (62), passed across at least a portion of the input drive element (42).</p> |
