APPLICATION FILE -WlLLlAl\I PRELLWITZ, OF
EASTON, PENNSYLVANIA, asstone re. "ran lNGERbOLL-EERGEANT DRILL COMPANY, OF NEW' Y@RK,- =Nr Y1 A (JORPORATEON OF WES?! VlRGlNlA.
nisoi-iases vatviz FOR Ftuin=ooaiassessos a I A lication filed April1,1905. $erisl in. 2.5mm.
Be it known that LWKLLIAM PRELLwrrZ, a Citizen of" the United States,a11d a resident of" Easton, in. the county of Northampton and State of Pennsylvania, have invented a new and useful improvement in Discharge-Valves l'or e lind-Compressors, oiwhich the follow ing is a specification.
The object of this present invention is to provide certain improvements in the construction, form, and arrangement of the several parts of a dischargovalve whereby a removable guide for the valve may be em ploycd and in which means are provided for yieldingly holding the discharge valve seat and the removable guide in. position.
An embodiment of this invention is represented in the accompanying drawings, in which-- Figure 1 represents a portion of a fluidcompressor cylinder in section with the discharge-valve shown in position therein, said dischnrge-vnlvo being also shown in longitudinal central sec ion. Fig. is a top plan view o l" the val ve-seat. Fig. 3 is a plan view oi the top plate of the laminated valve. Fig. 4 is a plan view of one of the other plates of the valve. Fig. 5 is a side view oi the removable valve guide, and Fig. 6 is a top plan view of the same.
The inner wall of the cylinder is denoted by 1. its outer wall byl, and the outlet-port between the walls by 3. The outer wall has a hole 4 therethrough of sullioient diameter to permit the insertion and removal of the valve and its seat. The inner wall 1 of the cylinder is also provided with a hole5 therethrough, the upper portion of which is enlarged to produce anannuiar shoulder 6.
The valve-seat herein shown comprises a central or disk portion 7, an outer or ring portion b, and connecting-ribs 9. wall of the ring portion 8 has an easy sliding oi the valve-seat lit within the walls of the hole 5 in the inner wall 1 oi the cylinder.
This ring portion 8 of the valve is further provided with an annular flange 10, which abuts against. the shoulder 6 when the valveseat is in position.
The valyewage is denoted by 11, and it has a lhingcd head l2*, which is bolted or otherwise secured to the outer wall 2 of the cylinder around the hole 4.
The outer Specification of Letters Patent.
I l l l l i l i l l i i l l l the valve guide and Patented Jan. s; ieoef The discharge valve proper is, herein shown as of laminated form, in the present instance comprising three disk-plates 12, l3, 14. A removable centrally-arranged guide for the valve comprises a plate laffrom which uprises a plurality of guidofingers 16, the outer walls of which engage the inner walls of the hole 17 through the center of the laminated valve. This central valve-guide is preferably countersunk into a recess 18 in the central portion 7 of the valve-seat for. holding the guide, and thereby the valve, against lateral movement. The head 12* of the ca 11 has centrally-arranged dcpend ing hollow post 19, the bore of which is open at both ends. This post is provided with an annular shoulder 20, between which and the top plate 14 of the laminated valve is interposed a spring 21 for yieldingly holding the valveclosed. To prevent the lateral displacement of the lower end of this. spring 21 the top plate 14 of the laminated valve is preferably provided with an annular series of lugs 22, struck up therefrom. A pin 23 has an easy sliding fit within the bore of the hollow post 19, the inner end of which pin rests on the center of the plate of the removable valve-guide. An adjusting-bolt 24 has a screw-threaded engagement with the upper portion of the bore ot the hollow post 19, as shown at 2.5, which bolt has a reduced portion 26, which extends down into close proximity to the outer end of the pin 23 when the bolt is in position. i spring 27 is interposed portion of the between the screw-threaded bolt 24 and the outer end of the pin 23 for yieldingly pressing the pin a ainst the valveguide, and thereby norma ly holding the valve guide and seat in position under pressure. The strength of this spring 27 should be sullicient to exert a greater pressure upon seat than the excess of pressure from the cylinder due to the coinpression o'f the valve suilicient to open the discharge-valve against the tension of its spring 21. The reduced portion 26 of the bolt 24 is so arranged that even should the 100 spring '27 become broken or weakened the bolt will engage the outer end of the sliding pin .23 and limit its outward movement, thus preventing the valve-scat from lifting out of its hole a suflicient distance to permit the es- 5 cape of pressure around its outer walls.
It is to be understood that certain features a eentrally-arranged removable valve-guide of construction shown and described, but not claimed herein, form part of the subject matter of a copending application filed by me January 18, 1905, Serial No. 241,603, for improvement in discharge-valves for fluid-compressors.
What I claim as my invention is- 1. A valveseat, a valve, its spring for yieldin ly holding the valve closed, a removable vafive-guide engaged with the seat and means for yieldingly holding the valve guide and seat in osition.
2. Alammated valve, its seat, a support for the seat, a centrally-arranged removable guide for the valve, means for yieldingly olding the valve closed and means for yield ingly holding the valve guide and seat in position.
3. A valve, its seat, a support for the seat,
l 1 l l locked to the seat against lateral movement, means for yieldingly holding the valve closed and means for yieldingly holding the valveseat and valve-guide in position.
4. A'valve, its seat, a support for the seat, a centrally-arranged removable valve-guide comprising a plate countersunk into the valve-seat and guide-fingers uprising therefrom, a spring for yield-ingly holding the valve closed and means for yieldingly holdin" the valve guide andsoat in position.
n testimony that 1 claim the foregoing as my invention l have signed my name, in
presence of two witnesses, this 29th day of March, 1905.
