The valve housing (4) includes several annular grooves (8, 9, 10) in which several radial openings (11, 12, 13) are located, which open into the axial bore (5), through which the hydraulic valve (1) has a fluid connection with a pressure connection (P), a tank connection (T) and two consumer connections (A, B). The piston valve (6) is acted upon by the armature (3) of electromagnet (2) and includes two ring-shaped control sections (14, 15), which connect alternatively the pressure connection (P) and the tank connection (T) with one of the consumer connections (A, B) through axial movement of piston valve (6).

摘要： A variable coolant pump for a cooling circuit of an internal combustion engine that has a pump housing in which is mounted a hollow shaft that is driveable by a pulley. At one end of the hollow shaft an impeller is fastened which has vanes projecting into an inlet chamber and which is firmly connected via axial bridges to a cover disc. Through rotation of the impeller together with the cover disc, water can be sucked into the inlet chamber via an inlet connection piece of the pump housing and conveyed by the vanes into an annular passage of the pump housing. A guide disc with a contour corresponding to the impeller is further arranged between impeller and cover disc. The guide disc is guided by the axial bridges and can be displaced axially via a positioning unit by a piston located inside the hollow shaft.

摘要： A device for changing the control times of gas exchange valves in an internal combustion engine including a crankshaft driven component, and a camshaft component driven by a camshaft and affixed thereto is provided. The crankshaft driven component is connected to the camshaft component for power transmission via two pressure chambers. The pressure action causes a relative rotation or hydraulic adjustment of the camshaft component relative to the crankshaft driven component. In addition, the device has an impulse generator wheel fixed to the camshaft component, for ascertaining the position of the camshaft, and a spring attached to the two components for rotating the camshaft to a preferred position for starting the internal combustion engine. The spring is arranged outside the device in a hollow space located between the impulse generator wheel and the axial side facing the wheel, and is enclosed at least on two sides by the impulse-generator wheel.

摘要： Apparatus for adjusting the basic position of a camshaft adjustment unit of an internal combustion engine, includes a first structure secured to a crankshaft and a second structure secured to a camshaft and having a camshaft-distant end surface formed with one or more form-fitting and/or force-locking force-transmitting elements. A piston reciprocates between two end positions and is so operatively connected with the first and second structures that a displacement of the piston results in a rotation of the first and second structures relative to one another. In order to position the adjustment unit in the basic position and to prevent the adjustment unit from executing a rotation relative to the camshaft after occupying the basic position, a tool is attachable to the adjustment unit which tool is formed with counterelements which complement the force-transmitting elements to effect a non-rotatable connection between the tool and the adjustment unit.

摘要： Apparatus for adjusting a rotational relation between a camshaft and a timing pulley of an internal combustion engine of a type having a crankshaft for driving the timing pulley and a cylinder head for rotatably supporting the camshaft, includes a housing receiving a double-acting piston for displacement in an axial direction between two axially spaced end positions and defining with the housing two pressure compartments. Secured to the piston is a control bushing which is geared to the timing pulley via a first gearing and operatively connected to the camshaft via a second gearing. A hydraulic regulating unit is fluidly connected to the pressure compartments via fluid-carrying passageways for alternately supplying a pressure fluid to the pressure compartments to effect an axial displacement of the piston and thereby a positional adjustment of the control bushing, with the fluid-carrying passageways including, for movement of the piston into one of the end positions, two axially spaced distribution spaces which are fluidly connected to each other by transition zones arranged in angularly offset disposition.
