    摘要: The invention provides a control circuit arrangement for solenoid valves, which has a timer adapted to supply the solenoid valve with a higher attraction current during an adjustable time starting with the beginning of a switching signal for the solenoid valve. After the time interval a low hold current flows until the end of the switching signal. For this purpose there is a semiconductor switch adapted to switch the flow of current through the solenoid valve. A logic gate arrangement is connected with an input of the switch and the gate arrangement is supplied with the output signal of the timer arranged to be triggered by the switching signal and the output signal of an oscillation generator. This circuit arrangement makes is possible to reduce a higher attraction current to a lower hold current in a simple and cheap manner, there only being a small overall size and as significant advantages it is possible for the arrangement to be converted for complementary logic.

    摘要: The invention relates to a negative mold containing a plurality of mold portions which can be detached from each other. It functions in particular for the manufacture of shapes consisting of plastic. The two mold halves enclose a molding chamber receiving the material to be shaped. In the chamber is arranged at least one insert abutting at least one projection which together form the negative for a surface depression to be produced in the shape. On the insert a fastening shank is arranged with the transition region being located in the region of the associated mold portion surface and being formed as gradation. Thereby the insert in contact with the mold half covers completely the orifice of the opening containing the shank and, in addition, projects beyond the opening edge.

    摘要: A pressure control valve, which possesses a primary pressure port, a secondary pressure port and a venting port. For control of the secondary pressure a valve operating device is present which is actuated by a control pressure present in a control chamber. A mechanical spring device urges the valve operating device against the direction of action of the control pressure in such a manner that when ambient pressure obtains in the control chamber, it automatically assumes a basic setting, in which the secondary pressure port is connected with the venting port for fluid flow. It is in this manner that there is an automatic venting of the secondary pressure port when the control chamber is free of pressure.

    摘要: A machine tool is suggested, which has a headstock (111) and at least one tool changer (120). The tool changer (120) moves production tools (116) between a magazine position and a working position, at least one fluid power drive cylinder (1) being associated with it as a drive unit (123). On the drive cylinder (1) a locking device (52) is provided, which when a working pressure of the drive piston (6) drops below a predetermined value produces a mechanical locking action of the drive cylinder piston in relation to the housing. To release the mechanical locking, a setting force due to the working pressure must be overcome.
