Abstract
A device for silencing a flowing gas which includes a valve housing in which a valve is mounted. A separate pressure regulator is provided which is in communication with the flowing gas and which is responsive to gas pressure to thereby influence movement of a mechanical actuating device which controls movement of the valve such that the valve may be opened at least two different rates dependent upon the pressure of the flowing gas.
Claims6
A silencer device for silencing a flowing gas, comprising a valve (1), which is arranged in a valve housing (2) through which the gas is flowing, a separate pressure regulator (4) provided exterior of the valve housing (2), a conduit (3) for communicating gas flowing to the valve housing (2) to the pressure regulator (4) so that a portion of the gas flows to the pressure regulator, whereby a pressure force of the portion of gas is convertable in the pressure regulator (4) to a displacement motion for influencing of a separate mechanical actuating means (5), by means of a piston rod (8) which is displaceable outwards of the pressure regulator (4) for acting on the actuating means (5), which in turn makes the valve (1) openable at at least two different predetermined opening velocities and wherein the actuating means (5) has an increase ratio after each of at least one predetermined gas pressure has been reached, whereby the opening velocity of the valve (1) increases for each ratio increase.
A silencer device for silencing a gas flowing through a conduit, comprising;
- a valve (1), which is arranged in a valve housing (2) communicating with the conduit through which valve housing the gas is flowing, a pressure regulator (4) exterior of the valve housing (2), a tap conduit (3) for directing a portion of the gas flowing through the conduit to the pressure regulator (4), whereby pressure of the gas is convertable in the pressure regulator (4) to a displacement motion for moving a separate mechanical actuating means (5) the valve (1) being openable at at least two different opening velocities dependent on the pressure of the gas by means of the separate mechanical actuating means (5), and the actuating means (5) having an increased motion ratio after a predetermined gas pressure has been reached in the pressure regulator, whereby the opening velocity of the valve (1) increases.
