摘要： The injection-molding machine is operative when activated for performing a complete injection-molding cycle. The machine includes a mold defining a mold cavity, a plastifying and injecting screw, and an hydraulic cylinder-and-piston unit for driving the screw. During the course of a single injection-molding cycle, negative-feedback control of the pressure in the mold cavity undergoes an automatic transition into negative-feedback control of the pressure in the hydraulic cylinder of the cylinder-and-piston unit. The transition is selected to be abrupt or gradual, and if gradual there will be a transitional interval during which a composite negative-feedback control of both the mold cavity and hydraulic cylinder pressures is occurring.

摘要： An adjustable hydrostatic pump (10), in particular a piston pump, is proposed, whose cam ring (22) is adjustable via a hydromechanical adjusting assembly (35) and which has a device for active noise abatement. A pressure chamber (39) of a adjusting piston (37) acting upon the cam ring (22) is acted upon by pressure changes, via an additional control unit (47) parallel to the hydromechanical pressure controller (41), in such a way that the oscillating actions of power-train forces on the hydraulic fastening of the cam ring (22) are reduced, thus lessening the noise produced by the piston pump.

摘要： The hydraulic setting device has a differential cylinder (11) whose annular space (14) is continually subjected to pressure by a pump (16). The pressure space (18) at the large piston surface is connected to the pump via a connection conduit (41). A conduit branch, which leads to a control valve (21), emerges from this connection conduit (41). At the other end, this control valve is in connection with a return conduit (26). The pressure in the conduit branch (19), and therefore in the pressure spaces (14, 18) of the differential cylinder, can be varied by appropriate activation of the control valve.

摘要： A magnetic linear drive includes an elongated cylindrical armature which is supported for axial displacement in a guiding pipe made of a pressure-resistant material. Two axially spaced solenoid windings are mounted on the guiding pipe and are interconnected by a permanent magnet. The solenoid windings are provided with lateral magnetically conducting cores the ends of which communicate with annular grooves formed in the guiding tube. The grooves are filled with a magnetically conductive material forming the poles of the electromagnet. In the region of the poles, the armature is formed with control flanges of different depths which are acted upon by the magnetic flux to impart the axial movement to the armature. One end of the armature is formed with a measuring flange which cooperates with measuring coils mounted on the guiding pipe.

摘要： An electromagnetically actuated directional control valve is proposed, whose control slide (18) can be switched against a restoring spring system (45) into three switching positions (39, 41, 42) by a double-lift magnet (12). The spring system (45) has a strong spring (31) and a counter-acting weak spring (37), which are disposed on both sides of the control slide (18). With a pushing magnet (12), the control slide (18) is solely deflected against the weak spring (37), which is supported on it over the entire lift area. With a pulling magnet (12), a spring plate (32), which centers the center position (39), is pulled way from the control slide (18), which now is displaced by the weak spring (37), against the force of the strong spring (31). The tappet (29), connected with the armature, and the control slide (18) are separate independent components, which only form a frictionally connected operative connection.
