摘要

Activator of the drawer for security system against crashes, security system against overflows, method of performance of activator of the drawer and drawer actuator presents: an activator of drawer for a security system against overflows, the activator of the drawer comprising a piston edu The river (30,70) and a secondary piston (20,22), the primary piston (30),70) comprising a primary axis (70), and a primary piston head (30) arranged sliding mode in a first cylinder (15) having a primary cylinder head (13) and supplied with a hydraulic fluid port (12) to facilitate the supply of hydraulic fluid to the ICA Call the first piston (30,70) in said first cylinder (15), the second piston (20)22) comprising a second axis (22) and a second piston head (20) arranged in a second cylinder (16) and a second cylinder head (14) and supplied with a hydraulic fluid port (40 and) to facilitate the supply of hydraulic fluid to actuate the second pis So (20) in the second cylinder (16), the second piston (20)22) arranged to act on the first piston (30,70), characterized by the fact that the said second piston (20,22) comprises a member (40) movable to a position engaged to act between the first axis and the second cylinder head (14) to lock the first shaft ( 70) in an extended position.
