    摘要: A solenoid valve having a first seat valve for performing a closing function and a second seat valve, connected in parallel thereto, for a pressure-limiting function. A pressure medium spilled by the second seat valve flows off through a flow-off bore acting as a throttle. Pressure surges are thus largely avoided in the part of the brake system located on the flow-off side. The solenoid valve can be used in controlled-slip hydraulic brake system of motor vehicles.

    摘要: The valve (10) has a seat valve (27) comprising a hollow cone-shaped valve seat (24) and an hemispherical shutoff element (26). An afflux bore (23) having contact with a pressure-medium inlet (19) discharges centrically into the valve seat (24). A solenoid armature (30) acting upon the seat valve (27) in opening fashion grips a push rod (25) comprising the shutoff element (26). The solenoid armature cooperates with a pole body (42) according to the flat-type armature principle. A preloaded return spring (39) acting on the seat valve (27) in closing fashion is arranged between the pole body (42) and the solenoid armature (30). The valve (10) works as a proportioning valve, because, in addition to a suitable design of the seat valve (27) and push rod (25), the magnetic force is infinitely variable and, together with a hydraulic force, has a monotonously increasing course as the valve opening stroke increases, while the spring force—which also has a monotonously increasing course as the valve opening stroke increases—has a positive slope that is greater than that of the course of the magnetic and hydraulic force.

    摘要: The invention relates to an electromagnetically actuated, controllable valve with first and second valve stages, of which the first stage is actuated by an armature and the second stage functions automatically. An opening cross-section of the first valve stage is small and an opening cross-section of the second valve stage is larger than said opening cross section of said first stage. The first valve stage when in a closed position keeps the second valve stage closed. When the first valve stage opens a spring element opens the second valve stage. The valve according to the invention has an advantage of an only slight actuating force, and the total actuating force is actuatable exclusively to the first valve stage, and the further advantage of a large opening cross-section and hence a low flow resistance.

    摘要: A valve assembly with a housing, a master valve and an auxiliary valve and an armature for the auxiliary valve and an electromagnet is proposed. In previous valve assemblies, in which the auxiliary valve, openable via the armature, serves to open the master valve, a master valve closing element is coupled via an idle stroke arrangement to the armature of the auxiliary valve closing element. If the armature traverses a first partial stroke, then the auxiliary valve is opened; if the armature traverses a further partial stroke, then via the idle stroke arrangement it can lift the master valve closing element from a master valve seat, if hydraulic forces are slight enough. Instead of the idle stroke arrangement, the master valve closing element is given its own armature, which is rigidly joined to the master valve closing element and acts in the opening direction. The valve assembly of the invention can advantageously be used in hydraulic vehicle brake systems that are set up for automatic braking. The smallness and the simplicity, thanks to the solid connection of the master valve closing element to its own armature, are advantageous.
