Abstract

Perfections introduced in a valve comprising: a valve body having an inlet passage and an outlet passage; a valve seat in said body between the entry and exit passages; a valve member mounted for movement in and out of closed and open relation to the seat; cylinder means mounted on the valve body with one end disposed adjacent the valve seat and the other end remote from the valve body; an annular piston movable alternately in the cylinder means for movement therein and having opposite faces; a tubular plunger guide fastened coaxially within the cylinder means in spaced relation radially inwardly with respect to the wall of the cylinder means and defining an annular passage therebetween; said piston sealed in sliding between the cylinder means and the piston guide and movable in sliding in said space; means connecting the plunger to the valve member for moving the valve member to and from the valve seat; said piston guide having an opening therein and an auxiliary or pilot valve seat surrounding said opening; an auxiliary valve mounted for opening and closing movement relative to said auxiliary valve seat; second cylinder means mounted on the valve body; an auxiliary valve piston movable alternately in said second cylinder means; means connecting the auxiliary valve plunger with the auxiliary valve to move the auxiliary valve to closing application with the auxiliary valve seat; spring means connected for operation for charging the auxiliary valve to an open position out of engagement with the auxiliary valve seat; fluid passage means from at least one of the passages in the valve body to admit fluid under pressure from the valve body passages through the valve seat in the body and through the opening in the piston guide when the auxiliary valve is open and the space between the plunger and the plunger guide to act on one of the faces of the plunger to move the plunger in order to move the valve member to the closed position; and aeration means capable of being selectively operated in fluid communication with said space to selectively aerate the pressure of said space when said auxiliary valve is closed to allow the fluid pressure acting on the other face of the plunger to move the plunger to move the valve to the open position.
