The liquid flowing through the outlet pipe 4 will have a tendency, to draw the ball back into its has moved free of the ball. To form a tight seal "between: the piston rod and the outer wall 26 of the j cylinder, a compressible Washer 30 is placed within the cylinder about thepiston rod and adjacent the piston'l2 and slidable on the rod. The .inner wall '31 of thepiston is preferably made not atright angles to that of the piston rod thus forming a recess 32 inlthe side of the piston facing the compressible washer. Therefore, the piston will engage the compressible washer'on or about its outer peripheral. edge and will compress the same against the inner wall 33 of the cylinder head when in its 'outer position thus' preventing furtherleakage of the liquid from the cylinder through,theoutlet 27 disposed about the outer; end. of the piston rod 14;.
The primary purpose of the piston operating in the cylinder consists in means for the prevention of a water hammer, for after the piston passes'the free opening within the cylinder wall the outwardjmovement ofthe piston will be retarded and the speed of the same will be controlled by the escapement of the trapped liquid. within-the cylinder ipassingthroughthe space disposed between the piston rod andthe cylinder head.
