Abstract
A hydraulic device includes a rod connected with a piston for limited axial movement relative thereto for opening a passage through the piston while pulling on same and closing the passage while pushing on same. The rod and piston are connected by a separable coupling including cooperating coupling parts formed integrally on the rod and piston for connecting and disconnecting the rod and piston by relative lateral movement therebetween.
