Abstract: The disclosure relates to an electronically commutated machine, more particularly an electronically commutated motor having a rotor on a rotor shaft, which rotor shaft can be actuated to rotate. For sensing of an angle of rotation of the rotor shaft, a signaling means is provided, which comprises a retaining element and a magnetic element disposed on the retaining element. A retaining element made of ferromagnetic material is proposed, the magnetic element being placed onto the retaining element from the outside and being retained thereon by magnetic force. The proposal makes it possible to dispense with costly adhesive connections between the magnetic element and the retaining element. The disclosure further relates to an electronically slip-controllable braking system having an electrically commutated machine.

Abstract: A pilot device for a hydraulic directional valve includes a displacement sensor, a pilot valve, an actuating device, a coil assembly, and a circuit board. The displacement sensor has a sensor axis and the pilot valve has a valve axis. The valve axis and the sensor axis are arranged substantially parallel to one another so as to lie in a reference plane. The actuating device and the coil assembly are arranged adjacent to one another. The circuit board is arranged parallel to the reference plane. In each case, to establish an electrical contact, the coil assembly, the actuating device, and an electrical plug connection are either soldered directly to the circuit board or are in breakable electrical contact with a respectively associated, rigid contact assembly. The contact assembly is soldered directly to the circuit board.

Abstract: A pump device for a brake system of a motor vehicle has a housing, a pressure piston which delimits a pressure chamber in the housing for producing hydraulic pressure mounted in the housing in a longitudinally displaceable manner, a return spring assigned to the pressure piston, a non-return valve which separates the pressure chamber from a pressure connection and only removes the separation when the hydraulic pressure in the pressure chamber is greater than in the pressure connection, and an electromagnetic actuator which includes an armature and an electrically energizable solenoid. The armature is arranged on the pressure piston and the solenoid in and/or on the housing. The pressure piston has an axial through-channel which opens out into the pressure chamber at one end and is assigned to the non-return valve at the other end.

Abstract: A hydraulic valve includes a sliding control member that delimits at least one constantly adjustable diaphragm. The sliding control member is configured to be moved in the direction of a longitudinal axis. The hydraulic valve further includes a locking device with a locking member that is configured to be moved counter to the force of a first spring transversely relative to the longitudinal axis. The hydraulic valve further includes at least one catch contour in which the locking member is configured to be engaged in such a positive-locking manner that the sliding control member is releasably retained in a catch position that is associated with the respective catch contour. The position of at least one catch contour is constantly adjustable in such a manner that the free cross-sectional surface-area of the at least one diaphragm is constantly adjustable in the associated catch position.

Abstract: A control arrangement for supplying a plurality of hydrostatic actuators includes a pump with an output connected to a circulating line that opens into a tank. The control arrangement has a metering port and an individual pressure compensator for each actuator. The individual pressure compensators are connected in series by the circulating line. Some of the pressure medium are configured to be branched off from the circulation channel for the respective actuator by the individual pressure compensators and fed to the metering port disposed downstream of the individual pressure compensator. The pressure medium that is not required is forwarded from each individual pressure compensator into the circulating line and is fed back from the last individual pressure compensator to the tank by the circulating line. The actuators are prioritized based on the order of their individual pressure compensators and move independently of the load pressure without expensive load sensing lines.

Abstract: What is disclosed is a hydraulic control arrangement for controlling a consumer, comprising a continuously adjustable directional control valve, an individual pressure compensator associated to the latter, as well as shut-off blocks arranged downstream from the directional control valve. In accordance with the invention, in the case of a insufficient supply of the consumer the pressure compensator is subjected not to the pressure in the supply (load pressure) but to a higher pressure, so that the control pressure difference at the supply control edge is raised.
