摘要： A preselection valve is for a hydraulic valve assembly with a switching element, a pressure input line, a first pressure output line and a first load pressure line with a load pressure inlet and output. The switching element is switchable from neutral to a first switching position. The pressure input line is connected to the first pressure output line in the first position. The preselection valve has a second and third load pressure line and a load pressure increasing device. The second load pressure line branches off the pressure input line upstream of the switching element. The load pressure increasing device is connected to the third load pressure line, which connects the pressure increasing device to the first load pressure line. The second load pressure line is connected to the pressure increasing device in the first switching position and the second load pressure line is blocked in the neutral position.

摘要： A hydraulic valve system has a valve housing, which has a first connection side and a second connection side. The valve housing has a through-hole for accommodating at least one piston. The valve housing has a third connection side with at least three hydraulic connections which are each connected to the through-hole via a line. The hydraulic valve system has a connection block with at least three hydraulic through-lines each extending from a first connection opening arranged on a housing side of the connection block to at least one second connection opening arranged on a hole pattern side opposite the housing side. Each of the at least three first connection openings is connected in a fluid-tight manner to one of the at least three hydraulic connections, and the second connection openings are arranged in a pre-defined hole pattern. A method for manufacturing a valve housing is also disclosed.

摘要： A cylinder device for a hydraulic lifting device has a housing and a piston rod axially movable relative to the housing. A rotary element is mounted on the housing in such a way that a rotary movement of the rotary element relative to the housing is possible and an axial movement of the rotary element relative to the housing is prevented. The piston rod has a movement transmission element, wherein the movement transmission element translates an axial movement of the piston rod into a rotary movement of the rotary element. A sensor unit is attached to the housing, which detects the rotary movement of the rotary element. Furthermore, a hydraulic lifting device with such a cylinder device, a chassis of a mobile device with a lifting device and a mobile device with a chassis are provided.

摘要： A hydraulic power unit has a housing, at least one pump element, a pressure collecting plate and an electric motor. The electric motor has at least one end shield, a stator and a rotor fixed on a rotor shaft. The at least one end shield has at least one partially circumferential functional recess extending between an outer and an inner circumferential surface of the end shield in the direction of a rotor shaft bearing seat. The functional recess thus formed permits the arrangement of functional elements at a central point of the hydraulic power unit in a space-efficient manner without negatively influencing the overall size of the hydraulic power unit.

摘要： A passenger restraint device of a fairground ride passenger unit, which has a passenger space, includes a position-adjustable restraint element and a lockable hydraulic adjuster which acts on the restraint element and has a cylinder-piston unit and a hydraulic accumulator. The hydraulic accumulator and the cylinder-piston unit of the hydraulic adjuster form a structural unit in that the cylinder of the cylinder-piston unit and a cylinder of the hydraulic accumulator arranged next to and parallel to the cylinder are part of an integrated cylinder assembly. The integrated cylinder assembly has a connection block with a switching plate on an axial end face, wherein the hydraulic accumulator is configured as a single unit and is detachably mounted on the switching plate.

摘要： The present invention relates to a dual-stage pump for a hydraulic system with a housing, a high and low-pressure pump element, a common pressure outlet and a switching valve that is arranged between a tank connection and the low-pressure pump element. The switching valve has a spring element and a piston being movable against a force of the spring element relative to the housing and having a closing member that can be lifted from a valve seat by a control pressure that is tapped on the pressure outlet and applied in a control pressure chamber. On the one hand, the invention is characterized in that the switching valve comprises a tappet that is movable relative to the housing and configured to move the piston and arranged between the control pressure chamber and the piston and has a smaller effective diameter than the piston. On the other hand, the invention is characterized in that the dual-stage pump comprises at least one valve that can be screwed into the housing, wherein a cutting edge of the valve is sealingly cut into the housing.

摘要： In a hydraulic drive of a tool, a piston is adapted to be acted upon by a pump via a pressure limiting seat valve and a parallel switching seat valve of a valve arrangement. A restriction is provided in a pressure line upstream of the pressure limiting seat valve which is connected to a tank on the flow-off side. A drain line leads from a working chamber of the piston via the switching seat valve to the tank. A closing side is adapted to be acted upon by pressure and an opening side is adapted to be acted upon by a force generated when the pressure limiting seat valve responds. The pump is adapted to be switched off when the maximum operating pressure has been reached, so that the piston will execute a return stroke. A pressure-increasing restriction is provided on the flow-off side of the pressure limiting seat valve.

摘要： In a solar generator, comprising a reflector and an electrohydraulic sun-position tracking device with at least one hydraulic cylinder and a hydraulic control seat valve, the reflector can be guided via the control seat valve to follow in synchronism with the course of the sun continuously and uninterruptedly. The control seat valve for regulating a pressure medium flow permanently supplied to the hydraulic cylinder comprises a seat surface and a sealing surface permanently pressed against each other with variable contact pressure, with which the pressure medium flow can be generated as controlled leakage. The sealing surface is made of a material that can be deformed by contact pressure. In the control seat valve, the controlled leakage is set in a control position at least substantially without lifting movement exclusively by the relative material deformation of the sealing surface on the seat surface, which deformation is set via the contact pressure.
