    摘要： A sensor valve (44) for indicating a status of operation of a hydraulic system (4) ar-ranged on an implement (3) connected to a hydraulic unit (1) and a control system (2) is described, in which a valve housing (441) accommodates a sensor-signal-inducing slide (442) which is displaceable between an inactive, first position (1) and an active, second position (II), an associated sensor (445) generating, in the first posi-tion (I) of the slide, a signal different from a signal which is generated when the slide (442) has been moved to its second position (II), and in which a drain channel (4414) forms a fluid-communicating connection between first and second valve ports (4411, 4412).

    摘要： The invention relates to a flow switch (10) comprising a flow channel (34) which has a liquid inlet (20) and a liquid outlet (28), through which a liquid can flow, and in which a permanently-magnetised switching body (54) is arranged that is able to be displaced, by the liquid, as a function of the flow, said switch also comprising a switching element (58) that can be magnetically actuated depending on the position of said switching body. In order to improve the flow switch (10) such that it is less sensitive to dirt particles carried along by the liquid, the invention suggests that an inner pipe (36) surrounded by an annular space (38) is arranged in the flow channel (34), receives said displaceable switching body (54), and has an inflow opening (42) fluidically connected to the liquid inlet (20), as well as at least one first and at least one second outflow opening (48, 50, 51), wherein said at least one second outflow opening (50, 51) is axially offset to the at least one first outflow opening (48) and said outflow openings open into the annular space (38). The annular space (38) is fluidically connected to the liquid outlet (28).

    摘要： The invention relates to a flow monitor for monitoring the flow of liquid or gaseous flow media through a flow channel (2), comprising a switching element (3), which is arranged in the flow channel (2) and around which the flow medium flows and which can be moved under the influence of the flow medium against the force of a restoring means (6, 7) from a neutral position to a switching position, in which the switching element actuates a reed switch (8) arranged next to the flow channel (2). In order to ensure for such a flow monitor that sufficient magnetic forces for actuating the reed switch (8) can be provided despite the narrow flow channel, at least one permanent magnet (4, 5) is arranged opposite the reed switch (8) outside the flow channel (2), and the switching element (3) arranged in the flow channel (2) is made of a material having high magnetic permeability and forms a magnetic bridge between the permanent magnets (4, 5) and the reed switch (8) in the switching position of the switching element.

    摘要： A flow-control switch device (10) for gas-fired wall boilers. The flow-control device (10) comprises a casing (11) of plastic material, defining a longitudinal duct (16) having an inner surface which extends between an inlet threaded pipe fitting (12) and an outlet threaded pipe fitting (13), and a magnetic float (17) for operating a reed-type switch (26). The float (17) consists of a cylindrical body of magnetic material, having an axial hole (16) for the fluid, a fore cylindrical portion (17A) and a rear cone-shaped portion (17B) facing towards the inlet threaded pipe fitting (12); the rear cone-shaped portion (17B),and the inner surface of the longitudinal duct (16), define an annular thrust chamber (21) to entrain the float (17) by the fluid. Side ribs (25) enable the reed switch (26) to be removably positioned on side faces of the casing (11) of the flow-control device (10).
