Abstract (en)
[origin: US7029249B2] A micropump provided with a cylindrical body ( 1 ) containing a measuring chamber ( 10 ) defined by a piston ( 2 ) and communicating firstly with a tank via an inlet orifice ( 10 a) provided with an inlet valve, and secondly with the outside via an outlet orifice ( 10 b) provided with an outlet valve, the micropump being characterized in that the piston ( 2 ) is connected to an external reciprocating actuator, and in that at least one of said valves is constituted by a valve member ( 3, 6, 7 ) suitable for being driven in translation by friction contact with said piston ( 2 ) successively in one direction and then in the other, and whose stroke inside the chamber ( 10 ) is shorter than the stroke of said piston.
