HENRY J. BERRY, OF DETROIT, MICHIGAN, ASSIGNOR OFOllE-HALF TO ELLSWORT H Y S. BRYANT, F DETROIT, MICHIGAN.
PUMP CYLINDER AND VALVES THEREFOR.
Application filed J'uly 28, 1922. Serial No. 578,101.
' To all itmay concern:
Be it known that I, HENRY J. BERRY, 'a citizen of the United States, and residing at Detroit, in the county of Wayne and a State of Michigan, have invented new and to air and gas compressors, air pumps and similar machines for changing the pressure of gases, and .its object is to provide a constructioncf this character which will operate efli'ciently for a maximum of time and which can be constructed at. minimum cost.
This invention consists in a cylinder and a head therefor, a valve plate between the cylinder and its head, saidv valve plate being provided with novel valve seats for the inlet and discharge valves and with inlet and discharge passages, and valves of thin resilient sheet metal adapted to bend to open and close said passages. It further consists in inlet and discharge passages for the cooling liquid in the cylinder walls and in the cylinder head and in passages in said valve plate communicating with the passages in g the cylinder and head. It also consist in, the details of construction illustrated in the accompanying drawings and particularly pointed out in" the claims:
In the accompanying drawings Fig. 1 is a central longitudinal section of a compres: sion cylinder construction embodying my present invention. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a plan of the valve plate. Figs. 4 and 5 are perspective views of the inlet and discharge valves.
Similar reference characters refer to like parts throughout the several views, v l The cylinder 1 is formed with an internal flange 2 intermediate its ends provided with a circumferential shoulder 3 -to support the packing ring 4 which prevents leakage of the cooling liquid between this shoulder and 1 the circumferential shoulder 5 on the lining 6. The outer end ofthis lining fits tightly within the circumferential shoulder 7 at the outer end of the cylinder. -A piston 8 of.
by means of the screws is a valve plate. 10 having holes 16 to receive these screws and which is formed with passages 17 and 18 which communicate with the assages 11 and 14 inthe cylinder respective y. I
Secured to this valve plate and to the cylinder is a cylinder head 19 having a flange 20 and closure 21 to constitute a chamber 22 for the cooling liquid. Screws 23 secure this closure 21 in position. Packing gaskets 47 may ,be employed if desired. The cylinder may be formed with an inlet 24; for the cooling liquid and two passages,
not shown, in the upper shoulder? which register with the passages 25 (Fig. 3) in the valve plate and the passages 26 (Fig. 2) in the cylinder head, and the head is provided with an outlet opening-27 for the cooling liquid. It will be understood that the number of these passages 2526 may be increased or decreased as desired.
The cylinder head is formed with a circular groove 29 having an extension 30 which communicates with the passage 17 in the valve plate and the valve plate has a series of smaller holes 32-which communicate with this groove 29. The plate-also has a shal- -low groove 33 just within the circular rib 34 which extends into a recess 35 in the outer end of the lining 6. This plate also has a central boss 36 inthe plane of the rib 34 "and a second series of small holes 37 which are all within the circular rib 38 on the outer side of this plate. This rib is surrounded by a shallow groove 39 and by a ,second circular rib i2 whose outer edge is just within the outer. edge of the circular recess 40 in the head. This recess has an extension 41 which connects to the discharge passages 18 and 14' in the valve plate and cylinder respectively.
The head is formed with a shallow groove 43 around the recess 40 therein to receive the circular rib 42 and the discharge valve 4.4 of thin resilient metal preferably spring steel while the inlet value 45 is placed in the recess 35 in the upper end of the linin -6, a small clearance being allowed so the e go of the valve. .will not be pinched. The groove 33 is but a. few one-thousandths of an inch dee so that when the piston 8 moves outward, t e pressure within the cylinder whichv bends-the valve 45 would press it against the bottom of this groove 33 before breaking the valve. But-this valve is seatresilient metal and bend under t ed at tha'ttime on the rib 34 and the boss 36 and as these are accurately ground no leakage occurs. a
p A series of operating tests extending over many weeks demonstrated that this shallow roove 33 and the fiat surfaces surrounding it together with the thin' metal valve 45 constituted an ideal valve construction for compressors andother pumps for ammonia and other fluids. The upper valve 44 likewise lias a free movement to permit bending. The space within the circular rib 38 is depressed a few thousandths of an inch, sufficiently to permit the valve 44 to fit against this rib 38 but not sufliciently deep to permit the valve to bend beyond its elastic limit." This valve like the valve 45, is bent away from its seat by the gas passing through the holes 37 and the gas passes the straight edges 46 of this valve into the recess 40. Neither of these valves requires a spring to cause it to seat as they are of e pressure of the gas to permit it to pass but as soon asthe pressure is reversed, they seat themselves by their own resiliency. The
distance the valves are permitted to bend toward the valve plate is determined by the depths of 'the grooves in the valve plate while the distance they bend while open can be accurate] determinediby the rate of intake and disc large of the cylinder.
The details of construction and proportions of parts may all be changed by those skilleddn the art Without departing from the spirit of my invention as set forth in the following claims.
I claim-- 1. In combination, a cylinder, a valve plate closing the outer end thereof, a cyl-- inder head attached to the cylinder and valve plate, the cylinder, valve plate and head having intake and discharge passages for gases, the valve plate having holes extending from the intake and discharge passages in the headto the cylinder and having shallow grooves in which the discharge ends of these holes open,- and thin sheet metal valves adapted to engage the-head around said grooves to prevent return of the gases.
