摘要： The invention relates to a reciprocating compressor (10) of a fluid and to a method for assembling the compressor. The compressor includes a valve plate (14) and a cylinder head (13) arranged on the valve plate (14). The valve plate (14) includes a delivery port (18) passing through the valve plate (14) and a delivery valve (22). According to the invention, the valve plate (14) includes a recess (24) having a flat bottom (26) parallel to the valve plate (14), the delivery port (13) being provided in the bottom (26) of the recess (25). The delivery valve (22) is made of a blade substantially occupying the bottom (26) of the recess (25). The compressor (10) includes, in addition, a spring (28) supported between the delivery valve (22) and the cylinder head (13).

摘要： A micropump including two glass wafers (2, 8) with a machined silicon wafer (6) sealingly inserted therebetween. An inlet valve (12), a pump chamber (14) and an outlet valve (16) are arranged between an inlet channel (4) and an outlet channel (5). A pump diaphragm (36) forming one wall of the pump chamber comprises a thicker central portion (38) operating like a piston. A piezoelectric element (52) acts on the diaphragm via an intermediate part (64) to provide the pumping movement. The pump chamber (14) and the spaces (22, 24) linking same to the inlet and outlet valves are shaped so that the reduction in the inner volume of the micropump caused by a reduction in the volume of the pump chamber during the pumping movement is such that the air in the micropump is compressed to a pressure high enough to open the outlet valve, whereby said micropump is self-priming.

摘要： The invention relates to a check valve (10) to be disposed between a first pressure chamber (14), in which a first pressure (P1) of a fluid (30) prevails, and a second pressure chamber (16), in which a second pressure (P2) prevails, having a valve housing (12), on which a valve seat (18) is implemented, and having a blocking element (22), which is designed in a blocking position for the purpose of closing a valve opening (19) in the area of the valve seat (18), in order to block the connection between the first and the second valve chambers (14, 16) if the second pressure (P2) is greater than the first pressure (Pi), and is designed in an open position for the purpose of releasing the valve opening (19), in order to release the connection between the first and the second valve chambers (14, 16) if the first pressure (P1) is greater than the second pressure (P2), wherein said fluid (30) can flow in the open position along a flow direction (S) from said first pressure chamber (14) into said second pressure chamber (16). Furthermore, the valve seat (18) is implemented as an inclined face, which is oriented at an angle (α) greater than 15° and less than 80° in relation to the flow direction (S), wherein said blocking element (22) has a planar blocking lobe (24) made of a material which can be elastically deformed, which presses against the inclined face in the blocking position and lifts off of the inclined face in the open position because of the difference between the first pressure (P1) and the second pressure (P2), in order to release the connection.

摘要： The metering pump includes a synchronous electric motor (3,5,6,7), for example of the permanent-magnet type, which transmits its rotary motion to a speed reducer (13,18) which is in turn associated, by means of a connecting rod-crank kinematic system (21-23), to a piston (25) which is slidable in a hollow body (26) in which it defines a variable-volume chamber (27). The chamber has, at its top, openings (33,34) on which fluid intake and discharge valve means (35,36) act.
