As a result, by reducing storage, simplifying the components and reducing the necessary types, a significant reduction in the production and assembly side is achieved, an increased accuracy of manufacture as well as an increase in operational safety and service life. In further education. The control system is simplified and improved by the fact that the cylinder has one or more external channels - leading from one side of the solenoid to the other. This ensures that only a relatively small tree needs to be filled with the pressure medium, and the pressure medium is promoted in the simplest way and in every situation hydraulic pressure action leading back spring is located inside the cylinder * driving at dan most far elekfcrohydxauHseheji Serätea known of Bruck piston connected to the actuator nor applied to one side and is SückfUhrfeder moved in the opposite direction by one "are in! control both entgögengesetztea Bfrwegungen by alternating Beaufschlag"

The modern Serätr has a built-on motor! Electric motor 1 with an extended shaft, an attachment 2 with an impeller 2% an intermediate part 3 with an impeller 3% a guide body 4 and a cylinder with a Bruckkolbeji 6 * under the action of a Büekzugfeder arranged inside the cylinder 8 and is blind with an outwardly reaching piston rod 9 * The άβη.

The mode of action is as follows «

When the electric motor 1 is switched on, the impeller Z * presses the Sruökaedium over the Leiticorper 4 aum impeller 3 ^r »a © 4ass in, the fcei met-stage centrifugal pumps known manner- the underside of the cylinder 5 is fed the pressure medium * and on the pressure piston 6 for a binding effect is brought ».

When the electric door 1 is stopped and stopped, the spring pushes the piston 6 back into its starting position. Conversely, it presses the pressure plunger back into the flinder 5 via the channel 7 on the upper side of the piston 6. The lifting and / or sinking speed can be determined as required by the appropriate design and dimensioning of the section 10 ".
