VALVE FOR COMPRESSORS AND THE LIKE.
Specification of Letters Patent.
Patented April 30, 1907.
- Application filed December 4, 1906. Serial No. 346,310.
To all whom it may concern:
Be it known that I, WILHELM l/VOLF, a subject of the King of Prussia, residing at Reisholz, near Dusseldorf, Kingdom of Prussia, Germany, have invented new and useful Improvements in Valves for Compressors and the Like,.of which the following is a specification.
My present invention relates to improvements in valves specially suitable for compressors and belongingto that class in which a'tubular spindle is enlarged like the mouth of a trumpet toward the valve seat.
The invention consists essentially in con structing the valve of thin sheet metal and providing'the same with a concaved bottom which also consists of thin sheet metal and is rigidly connected thereto for example by soldering or brazing so that by bending the trumpet like part the bottom is also bent and vice versa; By this arrangement the advantage is obtained that the valve can be constructed of extremely thin sheet metal even for large valve openings. The sheet metal can be chosen much thinner than in the case of plane or arched plate valves, because the trum et like part of the spindle forms a triang ar stiffening for the arched "bottom when the valve-1s seen in vertical section. Owing to the possibility of'using very thin metal the resilient properties of the valve, which as, well known are very favorable for the efiicii are bette emphasized in operation than be fore.
Inthe accompanying drawing illustrating my! invention Figure 1, shows a suction valve an gs. 3 and 4 show modified constructions of suction and pressure valves and Fig.
. 5 shows the unro'lled spring used according to The tubes a-and z' of Figs. 1 and 2 are made of steel or of good gunmetal and are expanded j -lar valve-stem having a flared lower end, a concave sheet-metal valve-plate secured to and covering said flared end of the stem, and means to seat the valve.
at the bottom b pressure or othenmeans so that they exten in an easy curveto the seats f and n. 'In the suction valve shown in Fig.
1 this curved extension forms the faci the fac' The hollow space at the bottom of the vs. vs is closed by a thin sheet m'etal plate (1 or l which is concaved into the trumpet like part of the spindle in order to procy of the machine, are assured-and 2 apressure. valve in vertical sectlon. 1
e oi the valve, while in the pressure valve s own in Fig. 2 the edge'is bent up at m to produce ton h. Said bottom plate d or 1 can be attached by inserting its edge in, a groove cgo'r is formed in shaping the trumpet like end. The concaved plate is arranged to fit tightly and is brazed or soldered, so that it 1s securely fastened to the border.
It is of advantage to taper off the thickness of the sheet metal toward the edge of the valve so that this part e-will be more resilient of itself. By this means it is assured thatthe valve is closed without a shock. The entire valve consists therefore, as it were, of two resilient parts, one of which is formed by the triangularly stiffened trumpet part and concaved bottom and the the edge e.
In what manner the valve can be loaded by springs 2, 2' as well as uided and limited other by in movement by ribs 9 an 0 will be apparent from Figs. 1 and 2. In Fig. 1 the spring 2 bears against a flange 6, whereas the bent up border m serves the same purpose in Fig. 2.
In the construction shown in Fig. 3 the concaved bottom 1) of the suction valve is provided with an annular groove q, agalnst which the trumpet'like expanded'end of the valve a bears, these parts being connected 'by soldering or brazing. This valve (Fig. 3) is shown loaded by a flat spring'r which has a crown shape and is provided with downwardly extending tonguest, said 'springbein supported by lugs s, on the guide 9.
he pressure valve shown in Fig. 4 has a facing 12 formed by bending up the edge of i the concaved bottom u. I A stlll eater resiliency of the trum et like expan ed art is induced by provi ing openings w t erein. guch openings'can also; be provided in the vconstructions shown in the other figures. Further the springs can be omitted and the other means adopted to load the valves.
I claim 1.. A valve comprising a sheet-metal tubu- 2. A alve-comprising a'sheet-metal tubular valve stemhaving a slotted, flared lower end to increase its resiliency, a concave sheet-metal valve-plate secured to and covering saidfiared end, and means to seat thevalve.
3. A valve comprising a sheet-metal tubular valve-stem having a slotted, flared lower end, a concave sheet-metal valve-plate secured to and covering said flared end and having an annular portion turned above the flared end of the, stern. l
4. A valve comprising a sheet-metal tubular valve. stem having a flared lower end, a concave sheet-metal valve plate secured to and covering said flared end and having an annular portion turned above the flared end of the stem forming an abutment, a guide surrounding the valve stem having a flange formed thereon, and a spring surrounding tizihe guide bearing against the abutment and IS an e. l
