摘要： A fuel injector for fuel injection systems of internal combustion engines has a valve-closure member that is in working engagement with a valve needle and that coacts with a valve-seat surface positioned in an orifice of a valve-seat member to form a sealing seat. The fuel injector has at least one spray discharge opening positioned in the valve-seat member. Between the valve-seat surface and the spray discharge opening, a second surface that make a more acute angle with the center axis of the fuel injector than the valve-seat surface, is formed by the orifice of the valve-seat member. A closure element extension whose enveloping surface forms an obtuse angle with the contiguous contour of the valve-closure member is positioned at the downstream end of the valve-closure member.

摘要： A fuel injector, in particular a fuel injector for fuel systems of internal combustion engines, has a piezoelectric or magnetostrictive actuator, a valve needle operated by the actuator by way of a hydraulic temperature compensation device, and a valve closing body operated by the valve needle and cooperating with a valve seat face to form a scaling seat. The temperature compensation device includes a needle driving sleeve which surrounds a valve needle shoulder of the valve needle and, together with a needle driving shoulder, surrounds the valve needle in sections. In addition, the needle driving sleeve together with the valve needle encloses a temperature compensation space, and the temperature compensation space is connected to a fuel inlet of the fuel injector through a directional valve for filling the temperature compensation space with fuel.

摘要： A fuel injector, in particular an injection valve for fuel injection systems of internal combustion engines, has a piezoelectric actuator or magnetostrictive actuator sealed against a fuel by an actuator seal and it has a valve closing body actuatable by the actuator and working together with a valve seat face to form a tight seat. The actuator seal includes a sealing element on the inlet end and a sealing element on the injection end, both designed to be elastically deformable and frictionally engaged with an actuating sleeve. The actuator acts on valve closing body by way of the actuating sleeve, thus at least partially compensating the forces generated by the fuel pressure and acting on the actuator by way of the actuating sleeve.

摘要： A tubular valve housing includes a guide body for pressure fluid that is disposed between a valve body having a hollow-conical valve seat and a chamber of the valve housing, in which actuating means of the valve are received in the chamber. The guide body is penetrated by a closing body of the valve which divides the chamber from an annular conduit. The annular conduit carries the pressure fluid and communicates with the valve seat and has circumferential outlet openings of the valve housing. The guide body is braced on the valve body, with a face end contacting the valve body, and has guide conduits, fitting over an outline of the valve seat, which on the outlet side discharge into the annular conduit. The face end of the closing body, which cooperates with the valve seat, is a spherical portion that makes a transition with sharp edges to the cylindrical shaft of the closing body. With the guide body, the stream of pressure fluid emerging from the valve seat is diverted into the annular conduit, so that flow instabilities are largely without any effect on the chamber of the valve. The valve can be used in brake systems of motor vehicles.

摘要： The valve has a seat valve with a hollow-conical valve seat and a closing member in the form of a spherical layer on a longitudinally drilled tappet. An inflow bore communicating with a pressure medium inlet discharges centrally into the valve seat. The largely pressure-equalized tappet is engaged by a magnet armature acting on the seat valve in a closing manner and by a restoring spring acting in the opening direction. The valve embodied in principle as a switching valve is controllable into stable intermediate positions on the basis of the following provisions: the cone angle of the valve seat is at most 90.degree.; the force at the closing member, originating in the restoring spring, is adapted such that it has a course that decreases monotonously with an increasing valve opening stroke (h); the magnet circuit of the valve is embodied such that the magnetic force (F.sub.M) exerted on the magnet armature and transmitted to the closing member is variable in infinitely graduated fashion and has a course that decreases monotonously with increasing valve opening stroke (h), the negative slope of which course is less quantitatively than that of the course of spring force.

摘要： A hydraulic unit for wheel slip control, which is located between a master cylinder and wheel brake cylinders. Reflection damping devices are installed in main brake lines located between the hydraulic unit and the master cylinder which damp pressure waves that originate at control valves of the hydraulic unit. When the control valves are triggered in the wheel slip control mode the pressure waves are largely kept away from the master cylinder. By the means of length adaptation of the main brake lines, the brake lines can also contribute to the damping.

摘要： A quiet closure check valve, including a housing having a valve seat toward the housing, a ball is associated with the valve seat to close the valve. The ball is received longitudinally displaceably in a recess of a spring-loaded support element that is defined by a bottom and a collar-like portion. Upon closure of the check valve, the support element rests on the housing, by spring action. The ball is lifted from the bottom of the support element and applied to the valve seat by the pressure of the fluid, in a manner free of spring forces. In this way, bothersome vibration of the ball is avoided.

摘要： A fuel injector for the direct injection of fuel into the combustion chamber of an internal combustion engine includes a valve needle, which is arranged in a nozzle body, is actuable by an actuator and acted upon by a restoring spring such that a valve closure member, which is in operative connection to the valve needle and faces the combustion chamber, is kept in sealing contact on a valve seat surface in the non-actuated state of the actuator. A surface of the fuel injector has a concave design in a transition region between the nozzle body and the valve-closure member.
