GOVERNOR VALVE FOR STEAM ENGINES.
Application filed September 18, 1920. Serial No. 411,127.
T 0 all whom it may concern:
Be it known that I, ALVA K. HINCHMAN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Governor- Valves for Steam Engines, of'which the following is a specification.
This invention relates to new and useful improvements in governor valves for fluid engines of the character capable of supplying a device with fluid at a predetermined pressure and has for its primary object the provision of a valve connected-to a balance piston by a hollow stem and adapted to open and close an intake port under the influence of pressure against itself and the balance piston and to direct the fluid into said stem when in an open position.
Another object of this invention is the provision of a governor valve for fluid engines of the above stated character, which shall be simple, durable and efiicient, and which may be manufactured and sold at a comparatively low cost.
'With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which T Figure 1 is a vertical sectional view, illustrating a governor valve for fluid engines constructed in accordance with my invention, and
Figure 2 is a horizontal sectional View taken substantially in the line 22 in Figure 1.
Referring in detail to the drawing, the numeral 1 indicates a casing having formed in one end a low pressure chamber 2 and which chamber is closed by a removable cover plate 3 provided with an outlet port 4 adapted to be connected to an engine or the like in any Well known manner. A piston 5 is reciprocally mounted within the low pressure chamber 2 and it is to be noted that said chamber is of a comparatively large size.
The other portion of the casing 1 has formed therein a comparatively small chamber 6 closed by a plate 7 and which is provided with an intake port 8 and a valve seat 9, the plate 7 being secured to the casing by fasteners 10. The intake port 8 is adapted to be connected in any well known manner to a high pressure fluid source (not shown). The chambers 2 and 6 are separated by a comparatively thick wall 11 provided with an opening to slidably receive a piston stem 12 provided with a longitudi- I nal passage 13 which opens outwardly through one end thereof for communication with the low pressure chamber and at its other end is provided with openings 1 L. The wall 11 is provided with an opening-.15 to permit stufling glands 16 t0 be secured in the casing and about thepiston stem 12 and the latter extends through the piston 5 and is detachably secured thereto. The other end of the piston stem 12 enters the chamber 6 and has detachably secured thereto a valve'17 provided with substantially i.- shaped passages 18. v
It is to be noted that certain of the walls ofthe passages 18 are directed upwardly or in the direction of the wall A of the chamber 6'while other walls of said passages communicate with the openings 14 of the piston stem 12. The valve 17 is provided with a beveled face 19 adapted to engage the valve seat 9 for the purpose of preventing fluid from entering the chamber 6 from the high pressure source (not shown).
Adjusting screws 20 are carried by the cover plate 3 and may be adjusted for the purpose of changing the stroke of the piston 5 and its stem 12.
In operation, the entering fluid presses against the valve 17 and unseats the same and simultaneously moves the piston 5 upwardly by means of the piston stem 12, whereupon the fluid passes into the chamber 6, through the passages 18 and 13 on into the low pressure chamber 2 through the longitudinal passage 13 and when the pressure within this latter chamber reaches a predetermined amount, the piston 5 is forced downwardly, seating the valve 17 cutting off the supply of fluid to the chamber 6 and simultaneously stopping the flow of fluid to the low pressure chamber 2.
A by-pass pipe 21 is connected with the inlet port 8 and to a port 22 communicating with the low pressure chamber 2 and said by-pass pipe is provided with a valve 23 which is adapted to be opened when it is desired to permit fluid from the intake port 8 to pass directly into the low pressure chamber and place the fluid therein under substantially the same pressure as that in the source (not shown).
An auxiliary chamber 24; is formed by one wall of the casing 1 and one face of the piston 5 and is provided with a port 25 which has connected thereto a pipe 26 provided with avalve 2'7 and which pipe is in turn connected to the by-pass pipe 21. lhe bypass pipe is also provided with valves 28 nd 29, fluid then may pass from the intake port 8 into the auxiliary chamber 2%, there by increasing the pressure in the low pressure chamber 2 that is required to force the piston 5 downwardly and seat the valve 11" against the valve seat 9. This increased amount of pressure must pass from the chamber 6 into the low pressure chamber 2 by way of the hollow stem 12.
While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.
llavingthus described my invention, what i claim is:
1. A governor valve comprising a casing having a low pressure chamber provided with an. outlet port and a chamber having an inlet port, valve seat formed in the inlet port, a piston in said low pressure chamber, ahollow piston stem secured to the piston and extending into the second chamber,
and valve in said second chamber and secured to the stem and adapted to engage the valve seat when in one position and having a passage in communication with the hollow stem to permit fluid to pass into the low pressure chamber from the inlet port when said valve is disengaged from the seat.
2. A governor valve comprising a casing raving a low pressure chamber provided with an outlet port and a chamber having an inlet port, a piston in said low pressure chamber, a hollow piston stem secured to the piston and extending into the second chamber, and valve in said second chamber and secur d to the stem and adapted to close the outlet port when in one position and having substantially L-shaped passages in communication with the hollow stem to permit pressure enterthe low pressure chamber from the inlet port when said valve is in an open position. a
3. governor valve comprising acasing having low pressure chamber provided with an outlet port and a chamber having an inlet port, a piston in said low pressure said by-pass pipe.
in testimony whereof I afliX mv signature.
