PUMP OR COMPRESSOR VALVE.
Specifications! Letters Patent.
Patented Mar. 7, 1922.
Application filed August 18, 1920. Serial No. 403,239.
To all whom it may concern:
Be it known that I, DAVID A. Dnonow, a citizen of the United States, residing at New York city, county of New York, and State of New York, have invented certain new and useful Improvements in Pump or Compressor Valves, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
This invention relates to valves of the spring-less type. v It is the especial object of the present invention to provide a valve of this class which shall be simple in construction, durable, highly efficient in operation, and. particularly adapted for use in pumps for liquids, although valves of similar construction may be advantageously used in compressors, blowing englnes, andlike apparatus.
It is a further object of the-invention to provide a valve of the class described which, when in normal or closed position, will be held under tension against its seat, and which when opened Wlll be pro erly supported to prevent deformation oi the valve disk, the construction also providing means whereby the pressure fluid will be directed only againstthe outer portion of the elastic valve disk, thus securing a large flow area with small flexing of the outer portion of the disk and thus securing proper action and long life of the valve.
For a full understanding of the invention, a detailed description of a construction embodying the same in its preferred form will now be iven in connection with the accompanying rawin forming a part of this specification, and t-e features fOIIlr ing the invention then specifically pointed out in the claims.
In the drawings- Figure 1 is a central section of the valve construction, and
Figure 2 is a top lan view thereof.
As illustrated in tile accompanying draw-- in s, the valve construction includes a body 1 orming inlet and outlet ports and circular valve seat 2, and a hub 3 centrally sup and of a thickness and quality best suited opposite the valve, but preferably of"con-' cavo-convex form, as shown, between which and hub 3 the valve disk 5 is securely held by screw 7.
It will be observed that the valve seat 2 has its edge bevelled or rounded and that the-hub 3 is cone-shaped, with its apex toward the inlet, so that the fluid passes through the valve seat and past the valve in substantially a single direction without sharp turns. With this construction, the valve disk will at all times be held under tension on its seat when the valve is closed, due to the concave surface of the hub 3 being slightly lower than the circular valve seat 2. The pumped fluid will be guided by the cone shaped hub to exert pressure on the valve disk near its peri hery and aproximatelyitangentially to t e valve, therey securing a uniform and easy opening of the valve and flow of the fluid, while the abutment 6, due to its cone shape, will permit full opening of the valve and at the same time prevent its opening so far as to weaken or deform the flexible disk.
What I claim is:
1. A valve for pumps and the like, comprising a valve body forming inlet and outlet ports and a circular valve seat, a cone shaped hub with its apex toward the flow of liquid and its valve supporting surface below" the level of the circular'valve seat, an elastic valve disk positioned on said hub and adapted to be held under tension on said seat, and an abutment for said valve.
2. A valve for pumps and the like, comprising a valve body forming inlet and outlet ports and a circular valve seat, a hub and supportin arms therefor, said hub having its valve isk supporting surface below the circular valve seat and its opposite end cone shaped to direct the fluid against the outer portion of the disk, a rubber disk valve su he (1 under tension on the valve seat, and a convex abutment for the valve disk, the whole-bein held together by a single screw centrally 0% the valve and abutment.
3. A valve for pumps and the like, comp-ported on said hub and adapted to be 2 v p j v 1,408,724
prising a valve body forming inlet and outletnports and a circular valve seat, a hub having its supportin surface below the circular valve seat, an an elastic valve disk supported on said hub and held under tension on the valve seat, said ports being arranged to direct the flow outward and near the outer edge of the valve disk.
4. A valve for pumps and the like, comprising a valve body, a circular valve seat, a hub and supporting arms therefor, an aloutment, a valve disk positioned between the abutment and hub, said hub being so POSI- tioned relatively to the valve seat that 15' the valve in its normal position will be held under tension on its seat, and guiding means for directmg the flow to the valve outward DAVID A. DE CROW.
