Abstract: The disclosure relates to a valve, comprising a main piston for actuating a main volumetric flow and a pilot piston for actuating a pilot volumetric flow. The main piston and the pilot piston are guided in a valve housing in a longitudinally movable manner, and the pilot piston can be actuated using a magnetic device. The position of the main piston can be set using the pilot piston in that a fluid pressure acting on the main piston is signalled via a fluidic connection into a pilot chamber comprising the pilot piston which keeps the main piston in the closed position thereof, said closed position cutting of the main volumetric flow.

Abstract: The disclosure relates to a valve, e.g., a proportional valve, comprising a main piston for actuating a main volumetric flow and a pilot piston for actuating a pilot volumetric flow. The main piston and the pilot piston are guided in a valve housing in a longitudinally movable manner, and the pilot piston can be actuated using a magnetic device. The position of the main piston can be set using the pilot piston which, based on the movement position thereof, signals the fluid pressure acting on the main piston into a pilot chamber via a fluidic connection or cuts of the fluid connection and connects the pilot chamber to a tank or low-pressure side via another fluidic connection into which a valve is introduced that closes in a leak-proof manner as soon as a fluidic connection is produced between the main piston and the pilot chamber.

Abstract: The disclosure relates to a valve, comprising a main plunger for controlling a main volume flow and comprising a pilot-control plunger for controlling a pilot-control volume flow. The main and pilot-control plungers are longitudinally moveably guided in a valve housing and the pilot-control plunger can be actuated by a magnetic device. The position of the main plunger can be adjusted by the pilot-control plunger in that a fluid pressure at the main plunger is communicated, via a fluid connection, into the pilot control chamber containing the pilot-control piston, which keeps the main plunger in its closed position blocking the main volume flow when the magnetic device is not actuated. When the magnetic device is actuated, the pilot-control plunger moves into a position in which the fluid pressure falls in the pilot-control chamber until the main plunger moves into an open position controlling the main volume flow.

Abstract: Disclosed techniques compensate for variable forces applied to a brazing head in order to more accurately maintain application of a desired lateral force by a brazing wire, filling wire or tracking finger extending from the brazing head to a component. Orientation of the brazing head is determined relative to gravity and the angle of a movable arm of the brazing head relative to a support body of the brazing head. A lateral force value measured by a lateral force sensor is adjustable based on the determined orientation of the brazing head and the determined angle of the arm relative to the support body in order to provide a corrected or adjusted lateral force value. At least a portion of the brazing head is repositioned relative to the component if the corrected lateral force value deviates from a predetermined value.

Abstract: A unitary adapter for attaching a cutting nozzle to a laser cutting head includes an inner cylinder made of ceramic, a conductive shield sintered to the outer sidewall of the ceramic cylinder, a threaded conductive holder (for accepting the cutting nozzle) mounted in an opening at one end of the ceramic cylinder, and a coaxial connector (for connection to external measuring equipment) attached to an opposite end of the ceramic cylinder. A pair of wires is formed to be embedded within the ceramic material and provide separate electrical connections between the coaxial connector and: (1) the threaded holder, and (2) the conductive shield. The various components are sintered to the ceramic body to form permanent attachments, creating a unitary structure less susceptible to the high levels of acceleration and elevated temperatures associated with the laser cutting process.

Abstract: A device includes a regulating piston (12) guided longitudinally movably in a housing (10) and interacting with a control edge (56), at a pressure supply port (P) that supplies a utility port (A) in regulating positions of the regulating piston (12) with fluid. The pressure can be preset via a fluid connection, pulling the regulating piston towards a closed position blocking this fluid connection due to occurring flow forces. The regulating piston (12) has a change of shape (60) from its general outer basic shape in the area of the control edge (56) of the housing (10) for a flow force compensation. A flow contact surface for fluid is provided causing a compensating force acting against the flow force to be introduced into the regulating piston (12), which flow force pulls the regulating piston (12) into an open position opposite from the blocked position.

Abstract: A valve, in particular for use as a pressure compensator or maintenance-type component (38) in hydraulically actuated hoisting devices (2), has a valve housing (54) with a control port (40), a fluid inlet (64) and a fluid outlet (66). A regulating piston (68) is longitudinally displaceably in the valve housing (54) and acts against an energy storage device (70) in the form of a compression spring, bringing the regulating piston (68) into positions forming a fluid-conveying connection between the fluid inlet (40) and the fluid outlet (66) or blocking this connection by a control pressure existing at the control port (40). A first orifice (88) in the regulating piston (68) connects the control port (40) to a receiving space (62) for the energy storage device (70) in a fluid-conveying manner. A second orifice (90) is in an intermediate part (72) in the valve housing (54).

Abstract: A control piston (12) is longitudinally displaceable in a housing (10) having two connection points (P, A) for fluid, and cooperates with a metering edge (34) of the housing (10) at a connection point (P). Point (P), in control positions of the control piston (12), supplies the connection point (A) with fluid via a fluid connection. The piston, as a result of occurring flow forces, tends to be drawn in the direction of a closing position that blocks one of these fluid connections. To compensate the flow force, the control piston (12) has, in the region of the control edge (34) of the housing (10), a shape modification (48) of its cylindrical exterior basic form (50), such that a flow contact surface (52) for fluid is created. The contact surface transfers a compensating force that acts against the flow force to the control piston (12) and that seeks to pull the control piston (12) into an opening position opposed to the closing position.
