Abstract (en)
[origin: DE102010009085B3] The valve (20) has a pump connection (P), a consumer connection (A1) for supply and discharge lines for a large swept volume of a double-action operating cylinder (10), another consumer connection (B) for supply and discharge lines for a small swept volume of the cylinder and a tank connection (T1) connected to a tank (17). A recess (34) forming a pressure discharge control edge is laid out in a piston collar (31) on fluid flow that is squeezed out of the small swept volume of the cylinder during slow movement, and exhibits dimension smaller than remaining recesses (32, 33) of the collar.
