COMPANY, 0F DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.
VALVE.
Application filed February 7, 1920. Serial No. 356,927.
To all whom it may concern:
Be it known that I, FREDERICK W. Honens, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Valves, of which the following is a specilication'7 reference being had therein to the accompanying drawings.
The invention relates to valves of the type in which a gradual opening of the port is effected as the valve is moved away from its seat. It is the object of the invention to obtain a simple construction of manufacture and one which has greater accuracy and is freer from certain defects than structures heretofore used for the purpose.
In the drawings:
Figure 1 is a sectional elevation of the valve;
Figure 2 is an elevation showing the valve partly lifted from its seat;
Figure 3 is a central longitudinal section through the ported cup; i
Figure et is a plan view thereof; and
Figure 5 is a developed view of the periphery of the cup showing the relative arrangement of the ports therein.
A is a casing. B the valve seat there-in, C a valve comprising a disk and a disk holder G. D a stem therefor, and E the operating handle, these parts being all of known con struction and cooperating with each other in the usual manner. Where a disk valve is withdrawn from its seat, a very slight movement will produce an opening of large area and consequently it is very diliicult to produce a gradual opening of such a valve.
With my improvement there is provided a cylindrical cup member F having an opening through the bottom and a ported peripheral portion, the ports being gradually uncovered upon the withdrawal of the disk from its seat andsaid ports being so arranged as to be successively opened. Preferably this cup member 1s secured to the seat of the valve and is of an internal diameter such as to substantially fit the periphery of the disk. I preferably also employ a composition disk for engaging the seat, said composition disk being'secured to a metallic disk holder G, which latter peripherally fits thefcup F.
To secure the desired gradual opening, the ports H, H', etc., 1n the'cup member F are arranged 1n spiral series, eachl successive port having its loweredge slightly above` the lower edge of the preceding port. Each port is also preferably 'formed with upwardly divergent side walls, so thatthe port area is increased at a uniform rate.
The cup F is preferably formed of pressed sheet metal and being die fashioned in construction. It is also accurately located on the seat and securely vattached thereto by forming a flange I on said seat which is spun or pressed over a cooperating flange J on the cup. Thus the structure is one which can be cheaply manufactured, readily assembled and which in operation will produce` the desired gradual opening ofthe valve.
What I claim as my invention is:
1. In a valve, a casing having anannular valve seat, a cup member having an opening through the bottom secured to said seat, said cup member being provided with a spi- `ral series of ports .formed with upwardlyv divergent side walls, each successive port having its lower edge slightly above the lower edge of the preceding port, and a disk closure engaging said seat and adapted to uncover the ports in succession.
2. In a valve, a casing` having an annular valve seat, a cylindrical cup having an opening through the bottom secured to said seat, said cup being provided with a spiral f series of substantially triangular shaped ports, a metallic disk holder reciprocal through the cup adapted,V to uncover the ports in succession, said disk holder being provided with an annular groove, a composition disk disposed in the groove in the metallic disk holder and adapted to engage the valve seat. 1
3. Ina valve, a casing having avalv seat, a cup member havingl an opening through the bottom secured tos'aid seat, said cup member being provided with a series of ports formed with upwardly'diverging side walls, each successive porthaving its lower edge'slightly above the lower edge of the preceding port, and a member adapted to uncover the ports in succession.
` In testimonywhereof I affix m signature.
FREDERICK W. ODGES.
