Abstract (en)
A pressure control valve (1) is integrated in the hydraulic cylinder (26) and is inaccessible from outside. The valve has a conical piston (15) with seating co-operating with the spring (10). When a pre-set oil pressure (P) is exceeded for the hydraulic oil, the conical piston or the ball is pressed against the spring. The oil then passes it through a front opening (24) in the inner housing enclosing the conical piston or the ball into a chamber (25) in the pressure control valve and escapes from it to a hole for discharging the oil.
