摘要： A fluid pumping device having a pump housing containing a piston chamber and a reciprocating piston, an inlet port and an outlet port allowing a fluid to enter the piston chamber during an instroke of the piston and be expelled during an outstroke. The device further having a valve switching element movably mounted against a valve base member, with a piston chamber aperture connected to the piston chamber and an inlet aperture and an outlet aperture connected respectively to the inlet and outlet ports of the fluid pumping device. The element has a grooves in the valve base member providing, a first communication between the inlet aperture and the piston chamber aperture so that fluid is sucked, into the piston chamber during part of the piston instroke, and a second communication aperture expelling fluid out of the piston chamber, through the outlet port during part of the piston outstroke.

摘要： A volumetric pump comprises at least one piston inside a cylindrical housing and means to cause a relative to-and-fro linear movement between the cylindrical housing and the piston in order to produce a stroke of the volumetric pump. This pump further comprises a bi-directional angular rotatable disc acting as a valve which connects alternately at least one inlet port and at least one outlet port to a least one pump chamber located inside the housing, and a driving mechanism arranged to dissociate at least partially the bi-directional angular movement of the rotatable disc with the to-and-fro linear movement of the housing. This driving mechanism is arranged such that the rotatable disc reaches an angular position at which it opens and/or closes the inlet and/or outlet ports when there is no relative to-and-fro linear movement between the cylindrical housing and the piston.

摘要： A volumetric pump (1) comprising a piston (2) and a cylindrical chamber (3), contains an inlet port (10) and an outlet port (11). Said piston (2) is actuated by a rotor (5) bearing an eccentric shaft (6). The shaft (6), being connected to the piston (2), causes said piston to slide back and forth inside the cylinder chamber (3) while having a bidirectional angular movement. The instroke of the piston (2) sucks a fluid (15) from the inlet port (10) through a first channel (12) into the pump chamber (3), said fluid being propelled through a second channel (13) to the outlet port (11) during the outstroke of the piston (2). The inlet (10) and outlet port (11) are opened and closed alternatively by the bidirectional angular movement of said piston (2) which acts as a valve for the said inlet and outlet ports (10, 11).

摘要： In one embodiment, a volumetric pump in a medical fluid delivery system comprises at least one piston in a hollow cylinder, the pump having at least one inlet port through which a medical fluid can be sucked into a pump chamber during an instroke of said piston, and at least one outlet port through which the medical fluid can be expelled during an outstroke of the piston. The piston or the hollow cylinder can be actuated directly or indirectly by a rotor. This rotor transmits on the one hand a bi-directional linear movement to the piston or to the cylinder and on the other hand, a bi-directional angular movement either to the piston or to another ratable element in order to open and close alternately the inlet and outlet ports.

摘要： A micropump comprises a valve system having one gasket (10) shaped to define three cavities (12, 12a, 12b) connected respectively to a piston chamber, an inlet port and an outlet port of the pump. A valve switching element (16) having at least one groove (17) is movably mounted on the gasket such that, during piston instrokes, said groove moves along a part of the gasket adjacent to the cavities connected respectively to the piston chamber and the inlet port of the pump, thereby creating a leakage between said cavities so that fluid is sucked into the piston chamber during a piston instroke. During piston outstrokes, said groove moves along a part of the gasket adjacent to the cavities connected respectively to the piston chamber and the outlet port of the pump, thereby creating a leakage between said cavities so that fluid is expelled out of the piston chamber through the outlet port during a piston outstroke.
