摘要： A microfluidic device (100) comprising at least one passive valve (PV, 120, 130), the passive valve being constituted by a sequence of a first carrier layer (CL 1) with an aperture providing a passage (P 1) for fluid flow, a first binding layer (BLI) with a first opening, a flexible layer (FL) with a through-hole (TH), a second binding layer (BL2) with a second opening, and a second carrier layer (CL2). Moreover, the flexible layer (FL) can move within a valve chamber (VC) constituted by the openings. Depending on the pressure difference across the passive valve (PV), the flexible layer (FL) can bend towards the first carrier layer (CLI) and close the aperture, while it opens the passage (P1) when bending in the opposite direction. Two of such properly oriented passive valves together with an intermediate active valve (AV) can constitute a one-stroke pump. A method for manufacturing such a fluidic device is also disclosed.

摘要： A diaphragm pump (5) for a seat adjusting device comprises a diaphragm (12) and a valve member (13, 14) which define a pump chamber (40) therebetween. An inlet valve (41) and an outlet valve (42) are formed on the valve member (13, 14). A pressure chamber (43) is in fluid communication with the outlet valve (42) and receives fluid discharged from the pump chamber (40) via the outlet valve (42). One of the diaphragm (12) and the valve member (53, 54) comprises a valve membrane (31) of a pressure relief valve integrated in the pump (5). The valve membrane (31) is integrally formed with the one of the diaphragm (12) and the valve member. The valve membrane (31) is moveable between a first configuration in which the valve membrane (31) closes a pressure relief channel and a second configuration in which the valve membrane (31) opens the pressure relief channel to allow fluid to be discharged from the pressure chamber (43).

摘要： The invention refers to a diaphragm pump (1) for use as a detergent dosage pump. The diaphragm pump (1) according to the invention comprises a pump housing (2), a working fluid chamber, at least one intake (3), at least one outlet (4) and one diaphragm (6) defining a wall of the working fluid chamber and reciprocatingly moveable, diaphragm driving means for reciprocating said diaphragm (6) and at least one check valve (7) including a spring biassed valve body (7a) for controlling ingress of the fluid into the working fluid chamber. The diaphragm pump is characterized by means for mechanically pushing the valve body (7a) into its valve seat.

摘要： A body-insertable apparatus having a volume variable chamber with a mechanism for taking in or throwing out predetermined fluid is realized. The apparatus has a housing, a balloon member, a passage way communication adjusting mechanism, a control circuit, and a power source and forms a volume variable storage chamber defined by the balloon member and an outer housing member. In the apparatus, a first passageway communication pipe communicates with the inner space of the balloon member and a second communication pipe communicates with the outer space. The communication control mechanism provides fluid communication between the first and the second communication pipe based on an electric current output from the control circuit.

摘要： The invention relates to a membrane pump (1) comprising a membrane (24) which can be actuated by a crank drive (32) and which, together with a concave pump body surface (8), encloses a pump chamber (38). The inventive membrane pump also comprises an inlet channel (4) and an outlet channel (17) which open into the pump body surface (8) at an inlet opening (9) and an outlet opening (20) respectively, whereby the membrane (24) has a membrane core (25) and an elastically deformable membrane ring (26), and the membrane core (25) has a convex surface that is adapted to the pump body surface (8). The inlet opening (9) is arranged in an area of the pump body surface (8) toward which the membrane (24) firstly approaches during a discharge stroke of the crank drive (32). The elastically deformable membrane ring (26) seals the inlet opening (9) before the crank drive (32) reaches the upper dead center.
