<p>Hydraulic device has a piston (2) inside a hydraulic cylinder (1) whereby the piston can be moved from its first position (E1) at one end into an opposite position (E2) at the other end of the cylinder. The hydraulic cylinder is connected to a delay device (8) fitted with auxiliary cylinder (9) with auxiliary piston (10) guided into it which can pause the movement of the piston in a halfway spot between the two positions. The auxiliary cylinder has two holes (16,17) for filling and emptying of hydraulic oil. A butterfly valve (14) can be connected within the auxiliary cylinder or piston to better determine the damping point.</p> |
