Abstract
The double-acting hydraulic cylinder pivots the pivoting part of a rotary plough in one direction or the other by means of hydraulic fluid operating the piston and piston-rod. The inflow and outflow pipes of the cylinder have a block which consists of a cylinder compartment in which is mounted a sleeve valve. Balls with springs are also positioned as blocking devices in the housing. The outside of the sleeve valve has conical surfaces which work in conjunction with the balls. On the front sides, inside the cylinder compartment, are springs mounted inside adjustment screws.
