    • A hydraulic unit having a hollow oil container which has a receiving space for oil between an external outer wall and an internal outer wall, and having a pump unit which comprises an electric motor and a pump which can be driven by the electric motor. Such a hydraulic unit is to be further developed in such a manner that it has only a low noise level, in which connection also sufficient cooling of the hydraulic fluid and of the electric motor should be assured. This is achieved in the manner that at least the pump, and preferably the pump unit, is included in an enclosure which is formed by the hollow oil container and at least one sound-damping element.

    • The present invention proceeds from an engine brake for a multi-cylinder internal combustion engine with decompression valves actuatable by pressurization of hydraulic pistons outside of the exhaust stroke of the working piston of the internal combustion engine, in particular at the end of the compression stroke. A radial piston pump is provided with internally supported radial pistons. The pump housing has a first housing section with the radial pistons, and a space for the eccentric which controls the radial pistons and a second housing section with the control outputs. Two distributor disks of the distributor unit are displaceably sealed off axially with respect to each other, the first distributor disk which separates a first pressure zone within the first housing section and a second pressure zone between the two housing sections from each other being adapted to be pressed axially against the first housing section and the second distributor disk which connects a control output in each case only with one pressure zone being adapted to be pressed axially against the second housing section.

    • In a power-brake system, a hydraulic pressure generated by means of a pump may be supplied, controllably in proportion to an actuation force via brake conduits, by a power-brake valve to individual brake cylinders. Control pressure conduits are connected to the brake cylinders or the brake conduits in the vicinity of the brake cylinders and these control pressure conduits are connected to the brake valve. The brake pressure at the brake cylinders may be fed back, via the control pressure conduits, as the control pressure for acting on the control end of the brake valve so that a control of the control plungers of the brake valve is carried out corresponding to the brake pressure build-up at the brake cylinders and, particularly when low brake pressures are desired, rapid pressure build-up times in the brake conduits are ensured. In addition, throttles may be provided in the control pressure holes in the brake valve so that the damping and closed-loop control behavior of the brake valve are positively affected. In addition, the brake conduits may be flushed from the direction of the brake cylinders by means of an auxiliary pump.

    • A hydraulic control device having a directional valve by means of which the direction of movement and the speed of a hydraulic consumer, especially a mobile working device can be modified. The hydraulic control device has a hydraulic pre-control device by which a control pressure can be applied, via a first control line, to a first control chamber and, via a second control line, to a second control chamber of the directional valve, and having valve arrangement in a first control line by which a largely free flow of control oil is admitted to a first control chamber and by which, by a throttling of the discharge of control oil, the movement of a control slide of the directional valve can be damped. To obtain an effective damping, but to avoid a delay of the start of the movement or of the end of the movement of the working device of a mobile working machine, the damping of the movement of the control slide can be controlled as a function of the control pressure in a first control chamber and/or of the control pressure in a second control chamber.

    • A hydrostatic radial pocket bearing for a servo cylinder is described, particularly for a high performance testing cylinder, of the kind as used, for example, in test rig or simulation technology. The radial pocket bearing is suitable for the highly precise regulation of the piston and for receiving large transverse forces acting on the piston rod. An even number of bearing pockets is uniformly distributed over the bearing periphery and fed from a source of pressure fluid by way of associated preliminary throttles connected to pressure supply conduits and by way of an associated connecting conduit. The preliminary throttles are formed by the bearing gap between a supply orifice and at least one outlet groove in an opposite bearing pocket, the bearing pocket being in the form of a reentrant depression either in the fixed or in the moving bearing portion. To reduce loss energy caused by leakage and at the same time increase the force carrying capacity of the bearing, the pressure drop of the pressure fluid flow axially away from the bearing pocket is different on both sides.

    • The present invention relates to a hydraulic secondary control system comprising a hydrostatic machine as a secondary unit which is connected to a pressure line in which an impressed pressure of approximately constant value is generated by a hydrostatic machine as a primary unit. The volume capacity of the secondary unit determines the torque delivered to a load and the torque needed by the load determines the speed of the secondary unit. When the desired speed and thus the volume capacity of the secondary unit is too high, the capacity exceeding the capacity of the primary unit supplying the pressure line, the pressure breaks down. To prevent this, the present invention provides to calculate a permissible capacity as defined by the rotary angle for the secondary unit in accordance with the nominal quantities of the primary and secondary unit. When the rotary angle of the secondary unit will be increased beyond the permissible value, the capacity is limited so that the volume of the secondary unit does not exceed the permissible value, thus maintaining the impressed pressure in the pressure line.
    • 液压二次控制系统技术领域本发明涉及一种液压二次控制系统,其包括作为次级单元的静液压机,其连接到通过作为主要单元的静液压机器产生近似恒定值的压力压力的压力管线。 次级单元的体积容量确定传递到负载的扭矩,负载所需的扭矩确定次级单元的速度。 当期望的速度因而次级单元的体积容量太高时,容量超过供给压力线的主单元的容量,则压力下降。 为了防止这种情况,本发明提供了根据初级和次级单元的额定量来计算由次级单元的旋转角度限定的允许容量。 当二次单元的旋转角度将增加超过允许值时,容量被限制,使得次级单元的体积不超过允许值,从而保持压力线中的压力。

    • An engine brake for a multicylinder internal combustion engine includes valves that can be periodically opened briefly, in each case outside the exhaust stroke. In the vicinity of the applicable valve drive, a hydraulic piston is provided that is triggered synchronously with the engine rpm via an associated control line by a hydraulic pressure distributor fed by a pump. To improve the accuracy of control over the entire engine rpm range, the various valves are assigned a central positive displacement pump that runs synchronously with the camshaft rpm and whose outlet line leads to the hydraulic pressure distributor, which has a distributor disk. In engine braking operation, an alternating connection of the applicable control line to either the pump outlet line or a low-pressure region of the hydraulic control circuit is effected synchronously with the engine rpm by means of the distributor disk.
