CONTROLLING-VALVE.
SPECIFICATION forming part of Letters Patent N 0. 732,588, dated June 30, I903. Application filed December 29,1902. derial No. 137,034. (No model.)
Too/ll whom, it may concern:
Be it known that I, THEODOR REUTER, a citizen of the Republic of Switzerland, residing at Winterthur, in the canton of Zurich, Switzerland, have invented a new and useful Controlling-Valve, of which the following is a specification.
My invention relates to improvements in controlling-valves for liquids, gases, steam, or air under pressure; and the object of my invention is to provide such a valve that can be operated with theleast amount of movements and power, at the same time being continuously in a tight fit with practically no Wear. I attain these objects by a device hereinafter described, and shown in the accompanying drawings, in which Figure 1 is a valve in connection with the stop-valve of a hydraulic rock-drilling machine; Fig. 2, a section of the valve on the line A B of Fig. 4:; Fig. 3, a section on the line C D of Fig. 4; Fig. 4, a top view of the valve; Fig. 5, a section through the valve-stem, showin g the bearing-surface of the valve-head; and Fig. 6, a face view of the valve-seat.
Similar letters refer to similar parts th rough-. out the several views.
The inlet-stud a is in direct connection with the stop-valve c bythe passage 1). The connecting-pipe (1 leads from this valve to the pressure-chamber e in the part g of the controlling-valve casing. The part f of the casing, which is screwed into the part g, is provided at its bottom with the seat or bearingsurface h, which is in direct contact with the bearing-surface t' of the valve-head it, the contact-surface being at right angles, or nearly so, to the center line of the valve-stem Z. The latter is provided at its upper end with a handle m, which has a stop it, moving between the cheeks 0, thus limiting the motion of the valve-stem. The valve-head is has on its lower end a recess for taking up a spring 19. It is furthermore provided with two channels q q, which pass from the pressure-chamber e to the bearing-surface i, and two channels r, which extend from the contact-snrface t' into the head and then unite radially into a common channel r, extending part the way up the stem land leading into the annular chamber s, which latter is connected with the exhaust-pipe t by a suitable stuffing box. The
partfof the casing is provided with twochannels u and n, which are situated opposite each other and extend from the seat h to the outlet-pipes w and 0c. The channels 0 and q-are so arranged that the opening on the head is of a channel 7" is diametrically oppositei'that of the corresponding channel (1 and that the connecting lines between the two corresponding openings form an acute angle to each other, as shown in Fig. 5. The valve-stem Z is held at the top in the stuffing-box y, and by means of the pressure in the chamber ea tight fit between the surface 11 of the valve-head k and the seat It is positively maintained, the more so since these surfaces "5 and h are easily turned true from the start, and wearing of the same rather makes the fit a better one. The spring 19 prevents the head from loosening when the chamber e is not under sufficient pressure.
The operation is as follows: Referring to the figures and assuming the valve-stem Z, or rather the handle m, to be in a position marked I, the liquid or gas, &;c. under pressure,which enters through the inlet b, valve 6, and pipe (1 into the pressure-chamber e of the controlling-valve casing, passes through one of the channels q into the corresponding channel u, from whence it is led through the pipe to to,- say, one side of the piston of a rock-drill or similar machinery, (not shown,) thus driving the piston forward. The liquid or gas, 850., which is ahead of the piston is exhausted into the pipe x, then passes through the channel valve-head it, from whence it is exhausted through the channel 1" into the annular chamber s and the pipe 15. When the piston has arrived at the end of its stroke-t. e., if the hole of the drill has attained the desired depththe valve-handle m is turned to the position II, whereby the channel 1) and pipe at is connected with the pressure-chamber e by the other channel (1, thus applying reverse pressure to the piston, which reverses the motion of the latter and exhausts the liquid or gas, 850., previously fed through the pipe to, which latter has before been the pressurepipe, the channel to, again into the head It, through the channel r and r,and then through the exhaust-pipe t.
This controlling-valve may be provided with but one channel q and 0"; but in this case the valve-head would have to be turned at a larger angle to acquire the same results.
Although I have explained my invention in connection with a rock-drill, I do not wish to confine the same to the application to this kind oi machinery.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a controlling-valve for liquids, gases, steam or air under pressure, the combination of a valve-casing with a valve proper, which latter consists of a valve-stem and valve-head whose bearing-surface is at right angle or nearly so to the valve-stem center line, said head projecting into a pressure-chamber of said casing, said head being provided with feed and exhaust channels, the latter extending along the inside of said valve-stem, all for the purpose of giving pressure to and exhausting from one or more Working chambers alternately, through channels of said casing, substantially as described.
2. In a controlling-valve for liquids, gases, steam or air, the combination of a valve-casing with a valve proper, which latter consists of a valve-stem and valvehead whose bearing-surface is at right angle or nearly so to the valve-stem center line, said head projecting into an inlet-chamber of said casing, said head being provided with feed and exhaust channels, the latter extending along the inside of said valve-stem, all for the passage of liquid, gas, steam or air through chambers of said casing, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
IHEODOR REUTER.
