CUSHION VALVE.
Application filed July 27,
This invention relates to valves for compressors, pumps and the like, but more particularly to a multi-ported plate valve, in which the valve is formed of thin sheet I metal and has aflat seating surface.
The objects of the invention are to efiiciently guide the valve in a simple and inexpensive manner and at the same time provide a cushion between the back stop and the valve preferably during the latter part of the valve lift.
One of the preferred ways to construct the valve is that shown in the accompanying drawings, in which Figure 1 is a sectional elevation of the valve assembly, and
Figure 2 is a detail sectional perspective View of the valve plate.
Referring to the drawings, the seat A may be of any suitable or usual form having the ports 13 and the back stop C is provided with an annular guiding ring D projecting towards the seat. These parts and the intermediate spacing washer E are held together by the bolt F and nut G.
The annular valve plate H is formed of thin metal having a flat seating surface and outwardly turned edges forming flanges, the inner flange J being as shown appreciably shorter than the outer flange K and not substantially longer than the extent of the valve lift, since one object of the invention is to guide the valve mainly by means of the outer and longer flange K.
In the illustration of the invent-ion in the drawings, the shorter flange J is shown shorter than the extent of the valve lift, which is the preferred construction. In such case the shorter flange is out of contact with the guide ring D when the valve is closed, but a cushion is formed behind the valve during the latter part of the valve lift, after the flange J has overlapped the guide ring. When the valve seats, the cushion is released, so that the valve does not lift against an initial cushion.
Suitable springs L are provided, seated in 1926. Serial No. 125,243.
the guide ring and bearing on the valve to aid in closing thevalve.
The valve constructed in accordance with this invention has been found to operate satisfactorily and well. Owing to the unequal length of the valve flanges, there is no bindin between the valve and the guide ring, the valve is lightened because of the smaller inner flange, and excessive stretching and weakening of the metal at the inner edge of the valve is avoided, due to the small amount of metal required to form the inner flange.
I claim:
1. A multi-ported valve, comprising a seat, an annular plate valve formed of thin metal having a flat seating surface and outwardly turned edges forming flanges, the inner flange being appreciably shorter than the outer flange and not substantially longer than the extent of the valve lift, a back stop having an annular guiding ring projecting between the flanges of the valve, and springs seated in said ring and bearing on the valve, whereby the valve is guided mainly by the longer outer flange and a cushion is formed between the valve and the ring during the latter part of the valve lift.
2. A mult-i-ported valve, comprising a seat, an annular plate valve formed of thin metal having a flat seating surface and outwardly turned edges forming flanges, the
inner flange being appreciably shorter than the outer flange and not substantially longer than the extent of the valve lift, a back stop having an annular guiding ring projecting between the flanges of the valve, and springs seated in said ring and bearing on the valve, the shorter inner flange of the valve being out of contact with the said ring when the valve is seated, whereby the valve is guided mainly by the longer outer flange and a cushion is formed behind the valve during the latter part of the valve lift after the shorter flange overlaps the said ring.
In testimony whereof I have signed this specification.
WILLIAM PRELLWITZ.
