Abstract
Control valve for starting and stopping the flow of a fluid depending on its pressure, essentially a pressure valve. It includes a valve case, with an entry chamber (5) into which the fluid is passed from a pressure vessel in such a way that the flow can be started and stopped by a control device (21), and with an exit chamber (6), which is connected to a network with a number of openable and closable exit positions. Between the entry and the exit chambers (5,6) there is a valve body (24). Under the effect of a spring (32) with a stronger force, and by the pressure in the exit chamber (6), the valve body takes up a closed position and separates the network from the entry chamber (5). With a lower force from the spring and by the pressure in the entry chamber (5), the valve body takes up an open position, so that the fluid can flow from the entry chamber to the exit chamber and further out into the network. A control piston (29) is moved by the pressure in the exit chamber (6) and is designed so that a predetermined higher pressure in the exit chamber causes the spring (32) to pass the higher pressure to the valve body (24), so that this tries to close. At a predetermined lower pressure in the exit chamber (6), the valve body is acted upon by the lower pressure via the spring, so that it tries to open. The control piston (29) is designed to move the control device (21) in such a way that when the piston is acted upon by the higher pressure, the flow to the entry chamber (5) is held closed, while when it is acted upon by the lower pressure it takes up a position so that the control device keeps the flow going. In the first position the valve body (24) is caused to be closed and in the second position, to be open.<IMAGE>
