VALVE.
SPECIFICATION forming part of Letters Patent No. 740,704, dated October 6, 1903.
Application filed January 3, 1903- Serial No. 137,735- (No model.)
To all whom it may concern:
Be it known that 1, WILLIAM F. SINGER, a
. citizen of the United States, residing at No.
1118 South Forty-sixth street, Philadelphia, Pennsylvania, have invented a new and useful Improvement in Valves, of which the following is a specification.
My invention relates to valves in which the flow of a fluid is controlled by variations of pressure on a diaphragm. It is intended to prevent the hammering of such valves by rapidly-repeated vibrations of thediaphragm, whereby both valve and diaphragm are quickly destroyed. It also assists in preventing any commingling of the fluids above and below the diaphragm.
The accompanying drawing represents, partly in vertical section, partly in elevation, a valve provided with my device.
Although the valve may be used to control the flow of any desired fluid and may in like manner be operated by any suitable fluid above the diaphragm, I will, for convenience only, describe its application to a refrigerating system. In this case the pipe 1 may be considered as leading from the compressor and the pipe 11 to the expansion-coils. The valve 2, the body 21 of which connects these, maybe either an expansion or an antifiooding valve. On the valve-body 21 is mounted a diaphragm-chamber 3, containing a diaphragm 31. Rising vertically and axially from the upper shell of the chamber 3 is a cylindric extension 32, in which reciprocates a piston 4, provided with rod 41, aperture 42, and boss 4.3. Axiall'y secured to the diaphragm 31 are the piston-rod 41 and the stem lateral ofiset 35 at the upper end of the cylinder 32 is threaded to connect with a tube 5, leading from the expansion -c0ils. The
ing.
' the oil 6.
1 tube 5 maywell be formed with a spiral coil 51. The port 36, connecting the offset 35 with the cylinder 32, is preferably placed as near as possible to the upper end of the cylinder. A body of oil, glycerin, or other liquid 6 fills the upper shell of the diaphragm-chamber 3 to a point preferably somewhat above that reached by the piston 4 at its highest.
Theoperation of my device will be readily understood from an inspection of the draw- It is of course clear that the condenserpressure, which acts against the lower side of the diaphragm 31, is much greater than the suction-pressure in the tube 5 and upon The adjustable spring 44 acts to compensate for this diderence, as well as for necessary changes of pressure. Whenever the condenser-pressure of the gas acting on the lower side of the diaphragm exceeds the combined forces of the spring and of the suction-pressure, the valve 2 will be open, as shown, and gas will pass through the pipe 11 to the expansion-coils. -When the expansionpressure increases beyond a predetermined point, such pressure will be transmitted through the oil 6 to the upper side of the diaphragm 31 and the valve will be seated, thereby cutting 06 the flow of gas to the expansion-coils. The movement of the diaphragm in either direction, however, will be greatly retarded by the piston t, which can only move in the cylinder 32 as fast as it is permitted by the flow of oil through the aperture 42.
In former constructions-d 6., those in which the piston and body of oil are omitted there exists for several seconds when the valve is either opening or closing a pulsative equilibrium between the pressures on the opposite sides of the diaphragm. While this lasts the diaphragm vibrates rapidly, thereby crystallizing its own structure as well as hammering the valve. My device if proportioned properly entirely obviates this difliculty, only a single slow movement of the parts occurring at each opening or closing of the valve. As it is important to keep the oil 6 or other liquid used out of the expansion-pipes, I construct the ofiset 35 with a wall between it and the cylinder 32 and place the port 36 at the upper end of this wall. For the same reason the pipe 5 is provided with the spiral coil 51. Of course any well-known form of baflie-separator would serve in place of the coil. The coil, however, has the great advantage of being free from joints, in which leaks are liable to occur.
What I claim is 1. A diaphragm-valve having a chamber, a cylinder connected to.said chamber, a piston movable in said cylinder, and a diaphragm in said chamber and connected to the valve diaphragm-chamber, a diaphragm by which said chamber is separated into two parts, they upper portion of said chamber being extended to form a cylinder, a valve connected to the lower side of said diaphragm, a piston movable in said cylinder and connected to the upper side of said diaphragm and means for the passage of a liquid from the space below to the space above said piston.
4:. In a diaphragm-valve in combination, a diaphragm-chamber, a diaphragm by which said chamber is separated into two parts, the upper portion of said chamber being extended to form a cylinder, a valve connected to the lower side of said diaphragm, a piston movable in said cylinder and connected to the upper side of said diaphragm and an aperture in said piston.
' 5. In a diaphragm-valve in combination, a diaphragm-chamber, a diaphragm by which said chamber is separated into two parts, the upper portion of said chamber being extended to form a cylinder, a valve connected to the lower side of said diaphragm, a piston movable in said cylinder and connected to the upper side of said diaphragm, means for the passage of a liquid from the space below to the space above said piston and means for the admission of gas to the space above said piston consisting of an ofiset, a wall separating said ofiset'from said cylinder and a port in said wall substantially at its top.
WILLIAM F. SINGER.
