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 hydraulic control, for example of a hydraulically operable working tool, includes a hydroconsumer that can be acted upon against a permanent force via a pressure source, and a switching valve with working power/pressure control function reacting against a spring force depending on a pressure and/or through flow volume. The switching valve connects the hydroconsumer with a tank for a return stroke of the hydroconsumer when the pressure source is switched off. The hydroconsumer can be hydraulically stopped with the return stroke via the pressure source by a pressure pulse and/or through flow volume pulse. In a hydraulically operable working tool, the hydroconsumer can be hydraulically stopped in the return stroke even before a predetermined end position is reached by switching on the pressure source.

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： A hydraulic component includes a component housing and a connection block. The component housing has an outer surface and an axial bore. At least one connecting channel extends from the outer surface to the axial bore. The connection block has a housing side with at least one connection bore, where the connection bore is in fluidic connection with the at least one connection channel. The outer surface of the component housing has a non-planar shape at least in the area of the at least one connecting channel, where at least one connecting bushing with a through hole is received in the at least one connecting channel and extends into the at least one connecting bore.
