摘要： A piston diaphragm pump for delivering doses of liquids, in particular surfactants, wetting agents or the like, has a pump piston (15) movably guided in a pump tube (13) that encloses the pump pressure chamber (12), and can be electromagnetically driven against the force of a return spring (17) by a magnetic coil (27) that surrounds the pump tube (13). In addition, a pump diaphragm (2) that is peripherically clamped to the pump housing (1) and faces on one side the pump suction chamber (4) is rigidly connected on the suction side to the pump piston (15). A longitudinal bore (18), within which is arranged a pump piston (15) provided with a piston valve (19), extends centrally through the pump diaphragm (2) and links the pressure chamber (12) to the suction room (4). In order to obtain the same pump capacity with reduced pump lifts, without the need for providing a specially sealed guidance of the pump piston in the pump tube, the working chamber located on the side of the pump diaphragm (2) opposite to the suction chamber (4) is designed as an additional pump pressure chamber (12') that is constantly connected to the piston longitudinal bore (18) that leads to the pump tube pressure chamber (12) by cross-channels (22) arranged in the pump piston (15) behind the piston valve (19).

摘要： The invention relates to a rotation angle sensor device (14) including: a rotatably mounted rotating member (28) comprising a plurality of circumferentially disposed, equally spaced markings (30), wherein the rotating member (28) is mountable for co-rotation with a shaft (24) or any other rotating portion, a detection device (32) for detecting the angular position of said markings (30), and a determination device (34) for determining the rotation angle (α) from the detected angular position. According to the invention the detection device (32) comprises two photoelectric sensors (36, 38) with a circumferential distance (D) between them, each sensor (36, 38) including a light source (40) and a light sensor (42), wherein each photoelectric sensor (36, 38) further comprises at least one pinhole structure (46) for limiting the cross section of the light beam illuminating the corresponding light sensor (42), and wherein each of the pinhole structures (46) has a non-circular cross section adapted for causing a predefined periodical sensor signal of the light sensor (40) by turning the rotating member (28) by one marking (30). The invention further relates to a stepper motor system (10) comprising a stepper motor (12) and a corresponding rotation angle sensor device (14), to a diaphragm pump for dosing a fluid comprising a corresponding stepper motor system (10), and to a corresponding control method for the energizing of a winding arrangement of the stator (18) of a stepper motor (12).

摘要： A diaphragm pump (10), in particular for use as a detergent dosage pump, comprises a pump housing (12), wherein the pump housing (12) comprises at least a first connector (14) and a second connector (46), a fluid chamber (16) connected fluid permeable to the at least first connector (14) and second connector (46), a reciprocating moveable diaphragm (18) defining a wall of the fluid chamber (16),at least a first check valve (44) allocated to the first connector (14) and a second check valve (48) allocated to the second connector (46), a first eccentric (24) and a second eccentric (32),a driving means (30) for actuating the first and second eccentric (24, 32), wherein the diaphragm (18) is actuated by the first eccentric (24) by a connector rod (20), and the first check valve (44) and the second check valve (48) are actuated by the second eccentric (32). This has the advantage that by actuating the first and second check valve (44, 48) depending on the movement of the diaphragm (18), in particular by a coordinated rotational movement of the first and second eccentric (24, 32), a gas, for example air, trapped inside the fluid chamber (16) may be evacuated from the fluid chamber, thus providing a self-bleeding diaphragm pump (10).

摘要： Metering pumps for the metered feed of liquids are fitted with an intake valve (8) built into an intake line from an intake container, a pump chamber (5) downstream of it with a pumping component (6) altering its displacement volume, a pressure valve (23) leading to the metering connector (22) and a vent and by-pass valve (20) built into a return line (21) leading to the intake container. In order to keep the quantity of by-passed metering liquid as small as possible while maintaining adequate venting, there is valve chamber (4) between the pressure valve (23) and the pump chamber (5) and separated from the latter by a return valve (12) and a movable control wall (13), in which is incorporated the vent (20) controlled by the control wall (13), opening on the suction stroke of the pumping component (6) and closing on its delivery stroke. There is also preferably in the valve chamber (4) a prestressed displacement wall (26) altering the volume of said chamber (4) in the opposite direction to that of the control wall (13).
