WILLIAM M. SAEFKE, OF MILWAUKEE, WISCONSIN.

To all whom it may concern:

Be it known that I, l/VILLIAM M. SAEFKE, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Visconsin, have invented a new and useful Valve, of which the following is a specification.

The present invention relates to improvements in valves, the primary object of the invention being the provision of a novel form of balance valve more commonly known as a pressure reducing valve, the same being provided with a removable valve bushing and combined balance valve and piston disposed in coactive relation with the bushing.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the c0mbinatio-n and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a vertical sectional view through the valve casing and the spring casing thereof with the valve in closed position. Fig. 2 is a detail sectional view of the valve bushing removed. Fig. 3 is a detail view of the balance valve and piston removed.

Referring to the drawings, the numeral 1 designates the valve casing which is provided with the partition 2 having the horizontally disposed annular band 3, with the annular shouldered portion 4: for the reception of the removable valve bushing 5, which is provided with the annular rim 6 to fit within the annular shoulder 4 and thereby properly support the bushing in the position as shown in Fig. 1. This bushing is provided with the circumferentially disposed apertures or ports 7 which are disposed in line with the port 8 of the partition 2 and with the inclined valved seat 8 at the lower end. The upper end of the bushing 5 is disposed within the collar 9 which is formed integral with the casing 1 and provides a receptacle for properly positioning the bushing in place and to which the spring casing 10 is attached, as clearly shown. By this means the flange 11 and bolts 12 properly lock the spring casing 10 Specification of Letters Patent.

upon the upper end of the sleeve 9 and thus lock the bushing 5 in place.

Disposed for vertical reciprocatory movement within the bushing 5 is the combined balance valve and plunger 15 carrying upon its lower end the disk 16 whose inclined peripheral edge forms a valve with the valve seat 8 of the bushing 5. The ports 16 are provided in the lower end of the combined balance valve and plunger 15, while the ports 18 are provided circumferentially of the combined balance valve and plunger in a line just below the lower. face of the plunger 17. The plunger 17 is provided with the packing rings 19 to provide a tight joint within the upper portion of the bushing 5.

In order to normally hold the combined balance valve and the plunger downwardly, and consequently the valve carried upon the lower end thereof, off of the valve seat 8 of the bushing 5, a coiled spring 20 is disposed within the chamber of the casing 10 and is provided with the disk 21 which is controlled by the adjusting screw 22. By this means the tension of the spring may be reg ulated as desired.

From the foregoing description, taken in connection with the drawings it is evident that the combined balance valve and piston is normally held in open position by means of the spring 20 and as the high pressure steam enters the inlet port, there is a jacket provided to surround the removable valve bushing 5 within the body of the main valve casing, so that the steam can enter through the ports 71S into the chambered portion of the balance valve and exhaust through the ports 16 thereof the valve 16 being unseated, into the casing 1. Should the pressure increase so that the combined balance valve and piston will be moved upwardly against the tension of the spring 20, the valve 16 carried by the balance valve is seated upon the valve seat 8 closing the ports 16 and moving the ports 18 out of registration with the ports 7. The pressure required to seat the balance valve is regulated entirely by the tension of the spring 20 due to its adjusting screw 22 and the disk 21. As soon as the pressure has been reduced, the spring 20 will again unseat the valve and permit the entrance of the pressure fluid within the chamber of the balance valve and again into the casing 1.

hat is claimed is:

1. A. pressure regulator valve, having a bodily removable bushing and valve member, said bushing having ports intermediate of its end and a valve seat upon its inner end while the valve member is a chambered cyl inder, one end of which is a piston slidably fitting in the bushing and the other end of which has a circumferential rim constituting a valve to cooperate with the valve seat of the bushing, said valve member further having two series 01 ports at the respective ends of the chamber, one series being for registration with the ports of the bushing while the other series is disposed to be projected exteriorly of the valve seat of the bushing.

A removable bushing and piston valve for a pressure regulated valve in which the bushing has an inclined valve seat upon its lower rim and is provided with a plurality of apertures through its wall intermediate of its ends, and in which the piston valve is insertible within the bushing from the valve seated end thereof and has both ends sealed and is provided with two series of apertures in the walls adjacent to the respective ends, the lower end of the piston valve being integral with the wall of the valve and pro vided with an outwardly extending inclined rim to correspond with the valve seat rim of the bushing to seal the lower end of the bushing, the apertures near the piston end being placed out of registration with the apertures of the bushing when the rims are together.

In testimony that I claim the foregoing as my own, I have hereto allixed my si nature in the presence of two witnesses.
