    摘要: Disclosed is a drive unit, in particular for a closing unit, an injection unit, or an ejector of an injection molding machine. The drive unit comprises a double-acting force transmitting element provided with a small and a large piston unit which are disposed in a cylinder. The large piston unit is adapted to be pressurized by a great force both in input and in output directions. According to the invention, both the large piston unit with respect to the cylinder and the cylinder with respect to a movable element of the drive of the small piston unit are spring-prestressed.

    摘要: An actuator is disclosed, in particular for a locking unit of an injection compression machine, comprising a hydraulic force translator with two piston units moving relative to each other with different effective areas. The foregoing enclose a pressure chamber together with a cylinder or spacer of the force translator. The smaller piston unit is electrically driven, wherein the axial displacement of the smaller piston unit may be transmitted to the cylinder. The cylinder can be fixed relative to a chassis of the injection compression machine by means of a hydraulic clamping device. According to the invention, the pressure necessary for clamping is delivered by a high-pressure reservoir which may be charged during the displacement of the smaller piston unit.

    摘要: A free-piston engine directed to reduced throttling losses at minimum expenditure is provided. The free-piston engine has an engine piston, and a hydraulic piston co-operating with the engine piston. The engine piston may receive application of a force in the direction of compression via a hydraulic cylinder. A pressure in a high-pressure accumulator means or a low-pressure accumulator may be communicated to the hydraulic cylinder via a switchover valve. Between the hydraulic cylinder and the switchover valve is a valve assembly including a control piston. A connection to the high-pressure accumulator means may be controlled open with the aid of the control land of the control piston.
