STEAM REGULATOR VALVE FOR STEAM ENGINES.
(Application filed Sept. 18, 1897.)
(No Model.)
UNITED- STATES PATENT OFFICE.
WILHELMUS JOHANNES HENDRICUS FRESEN, OF BRUSSELS, BELGIUM.
STEAM-REGULATOR VALVE FOR STEAM-ENGINES.
SPECIFICATION forming part of Letters Patent No. 636,130, dated October 31, 1899.
Application filed September 18, 1897. Serial No. 652,118. (No model.)
To all whom it may concern:
Be it known that I, WILHELMUS J OHANNES HENDRICUS FREsEN,engineer,a subject of the King of Belgium, residing at Brussels, in the Kingdom of Belgium,haveinvented a new and useful Improved Steam-Regulator Valve for Steam-Engines, (for which patents have been obtained in Germany,dated February 20, 1896, No. 90,077; in Hungary, dated January 22, 1897, No. 7,743, and in Austria, dated July 12, 1896, No. 46/2,792,) of which the following is a full, clear, and exact description.
The object of the present invention has relation to the securing of the uniform operation of steam-engines by means of a regulatingevalve, which valve is characterized, essentially, by the use of the alterations in the speed of the steam-current which occur during the working for the immediate actuation of a regulating-valve inserted in the steampipe connecting the boiler with the steam-inlet valve in contradistinction to the governorball regulators which effect the control of such valves or of the main slide-valve itself only through the resulting alteration in speed of the machine by means of mechanical trans-' mission. A regulator of this kind actuated automatically directly by the steam-current is illustrated in the accompanying drawings, by way of example, in onemodification.
Figure 1 shows a side view of the regulatorcover; Fig. 2, a vertical section of the regulator; Fig. 3, a horizontal section above the regulating-piston, and Fig. 4 a partial section at right angles to Fig. 2.
The valve-casing, which, according to the illustration,is inserted vertically in the steampipe, consists of two divisions B B, of which the upper division B connects, by means of the tubular support A,to the part of the steampipe coming from the boiler, and the lower division B connects, by means of the part S, to the tube proceeding to the slide-valves. Between the two divisions are placed two annular disks P P, closing tightly upon one another, of which the lower one is fixed and pro vided at its center with a sleeve or cylinder 0, upon which the upper revoluble disk is guided. The surface of both disks is broken through bya given number of radially-placed openings, and these latter can be adjusted so as to make larger or smaller openings by corresponding displacement of the disks. The turning of the upper disk is efiected by means of the piece sengaging in the toothingc. The axis thereof, which bears on the outside the crank-handle M, is rendered steam-tight by the stuffing-box b. The piston P Works in the cylinder 0, which is open at both ends. This. piston stands normally at the upper end of the cylinder and is so tightlyinserted that the weight will not without further force push the piston-rod T, as well as the Valves S S connected with it,out of this normal position. The valves S S are devised to shut off, more or less, the openings beneath them in the walls of the inner valve-casin g B which valve-casing forms a continuation of the connectingpiece S. The piston-rod T is guided above and below in bearings 0 O and the same rests at the lower end upon a little disk r, covering the spring R, and can further be brought into contact with the head r of the bar t, regulated from the outside. Any water of condensation can be let off through the channel Z, closed by a screw-plug.
The device is operated as follows: The steam-inlets of the annular disks P P are arranged for the normal working of the machine,and as long as thiscontinues unchanged no part of the regulator alters its position. If, on the contrary, the speed increases, then the steam passes out of S very quickly, and consequently flows in more quickly through A. Consequently the piston P receives a strong impulse in proportion to the speed of the steam, whereby the said piston is depressed in the cylinder 0 and the valves S S approach the openings in the cover, and the escaping steamis thereby checked. Here upon occurs, moreover, through the sudden collecting of the steam in B B a certain resistance, which again impels the piston P, with the valves S S upward until the equilibrium is fully restored. In the case of too sudden or too far a sinking of the piston P the piston-rod strikes upon the little disk r, and the same is again raised by the spring R, which latter also prevents the valves from sticking fast upon the sides of B If, how
ever,such a sticking fast should occur in spite of the spring R, the piston and the valves can be again raised by means of the outside bar.
I claim v A steam-regulator valve for steam-engines comprising a valve-casing connected to the steam-pipe by inlet and outlet connections, and having two divisions connected respectively to such inlet and outlet connections, and communicating with one another, adj ustable means controlling such communication between the divisions of the valve-casing, a cylinder opening at opposite ends into the respective divisions of the valve-casing, a pisston working in such cylinder and a valve connected to and controlled by said piston and controlling the connection of one of such Valve-casing divisions to the steam-pipe.
