VALVE MECHANISM.
Application filed April 5, 1922. Serial No. 549,835.
for compressors or other pumping machin-- cry.
An object of my invention is to provide an improved valve mechanism. Another object of my invention is to provide an improved valve mechanism for compressors or other pumping mechanisms in which smooth operation is insured. A further object of my invention is to provide an improved automatic valve mechanism for pumping devices in which breakage of valves or springs is reduced to a minimum and a very smooth and silent operation is accomplished. Other objects and advantages of my invention will hereinafter more fully appear.
In the accompanylng drawings I have shown for purposes of illustration one form which my invention may assume in practice.
In these drawings,-
Fig. 1 is a central vertical section through a fragment of the compressor cylinder with an illustrative embodiment of my invention employed in connection therewith.
Fig. 2 is a plan view of the bufier plate constituting a portion of my invention.
Fig. 3 is an edge view thereof and Fig. 4 is a central section on the line 4-4. of gill Fig. 2.
Fig. 5 is a plan view of the spring. Fi 6 is a side elevation of the spring before lnsertion in the assembled mechanism. I employ my invention with a cylinder $5 member 1 having a bore 2, said cylinder member being provided with a head 3 having a chamber 4 communicating with the bore 2 and constituting an extension of the counterbore oi the cylinder. Within the cylinder head is arranged a series of recesses 5, which recesses receive my improved valve mechanisms and of which recesses but one is shown. These recesses communicate with adischarge chamber 6 formed in the cylinder and with an inlet chamber 7 formed in the head. In the recesses 5 l locate my improved valve mechanisms, these comprising cooperating inlet and discharge portions, respectively designated 9 and 10, which porto tions are held in assembled relation by a .throu h bolt 11 and which are held in the oylin er head by the connection of the bolt 11 with a bar 12 which extends across the open ends of the recesses 5 in the head memat her a Considering the inlet and discharge members 9 and 10 separately, the former will be first examined. This comprises a generally annular member 13 traversed by a series of passages 14 which communicate with the inlet chamber 7 at one end and at the other with ports 15 which open through the lower side of the member 13. Ihe member 13 is provided with an annular shoulder 16 which seats upon a surface 17 on the head member 3 and serves to position the member 13 with respect thereto. The member 13 is also provided with a plurality of projecting bosses 18, of which but one is shown herein, these bosses serving as guides for the valve and spring later described and also supporting an annular guard plate 19 which is secured to the member 13 by bolts 20 and nuts 21, of which but one is shown. A central recess 22 is provided in the member 13 to permit the latter to pass down over a nut whlch will later be described and which holds the element 10 in position. An annular valve member of relatively thin material 23 seats over the ports 15 and is held normally closing the same by means of a spiral spring 24: of flattened material. This spring is best shown in Figs. 5 and 6 and will be noted to be ribbon-like and may be made up in practice by flattening a spiral spring of round stock. Between the lower side of the spring 24: and the guard 19 is a buii'er plate best shown in Figs. 2, 3 and 4, this plate being substantially annular and of substantially the same dimensions as the valve member 23. This bufi'er plate, which is designated 25, will be noted to be provided a series of corrugations 0r flexures whose axes of flexion extend radially with respect to the member 25. As a result of this construction, a light and resilient buifer plate is provided and possible breakage of the spring 24 or the valve 23 is practically eliminated by reason of the elasticity of the bufier plate and, further, a more silent operation is rendered possible. N
The element 10, which is the discharge element, comprises a member 26 which is similar to the member 13 in a number of respects. This member is traversed by a series of fiow passages 27 which open into .the space intermediate the members 9 and 10 and communicating with the cylinder counterbore 4, and terminate in ports 28 which are normally closed by an annular no bosses '33 corresponds to the v 410 parting from its which seats upon the annular shoulder 35 in the head member. 3. A nut 36 is threaded upon the bolt l1 and holds the member 26 with its surface 34 in engagement with the shoulder 35, while a nut 37 holds the Unember 13' with its shoulder 16 in engagement with the surface 1! of the head 2.
The mode of operation of this device will be readily apparent. Upon the suction I stroke of the piston, the valve 23 will be unseated, compressing the spring 24 and, by
reason of the spiral rm of the spring, the same may flatten down into a single plane and provide a very wide port opening. Owing tothe presence of the bufi'er plate 25 25, severe hammering ot the valve and spring are prevented. @n the compression stroke, the valve 29 will open while the valve 23 will be closed by the spring. The spring 30 and the butter plate 25' will oper to ate as did the spring 2t and bufier plate 25 in the intake position of my valve mechanism.
While l have in this application specifically described one form which m mvenas tion ma assume in practice, it wil be understoo that this form of the same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms without despirit or the scope of the appended claims.
What I claim as new and desire to secure by Letters Patent is:
1. A valve mechanism comprising a memher provided with a port, a thin valve overlying said port, a guard having a normally immovable relation to said member, a resilient member constituting per se a yielding stop spaced from said port and. supported by said guard, and a s ring of smaller cross section then said resi 'ent stop disposed between said valve member and said resilient member.

3. A valve mechanism comprising a member provided with a port, a thin valve overlying said port, a guard having an immovable relation'to said member, a corrugated resilient member spaced from said port and supported by said guard, and a spiral springdisposed between said valve memher and said corrugated resilient member.
