THROTTLE VALVE.
Specification of Letters Patent.
Patented Feb. t, l1922.
Application :tiled October 24, 1919. Serial No. 332,935. l
To all whom t may concern.'
l Be it known that I, PERRY HoMEn GENT- zEL, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts,have invented certain new and useful Improvements in Throttle Valves, of which the following is a specilication. The object of' my said invention is to provide an improved construction of throttle valve, the purpose being to provide a.,
valve wherein the` cutting or wearing on the valve proper by the opening and closing thereof will be reduced to a minimum, or practically eliminated, all as will hereinafter be more fully described and claimed.
Referring to the accompanying 4drawings which are madel a part hereof and on which lsimilar reference characters indicate simii steam inlet pipe B and steam pipe C leading to the engine are all of substantially a well known construction and arrangement. A poppet valve 10 preferably of monelmetal is-mounted on the valve rod 11 and is adapted to seat on a valve seat 12 in the casing between the p ipes B and C to control the fiow of steam from the boiler to the engine. Mounted @whe valve rod 11 in a posltion to normally cover the annular chamber 13 in line-:with the pipe C is a monel metal sleeve 15 formed with a closed upper end and an open lower end, and with a number of perforations in the part which will be above the chamber 13 when the valve is closed.
Said perforations are arranged in pairs, those of each pair being on diametrically opposite sides of the sleeve and in line with each other, so as to perfectly balance in operation. The lower edge of the lowermost holes Aare about one sixteenth of an annular chamber 1'3 and out through the pipe C to the-engine. A further continuation of the movement ofthe valve stem until the perforations are all uncovered enables v a full ow of steam from the supply' pipe to the pipe leading to the engine. By this means the flow of steam is not-only easily controlled, but the seating and unseating of the valve may be made easily, and without undue wear, or cutting.
Having thus fully described my said invention what I claim. as new and desire to secure b Letters Patent, is
1. A t rottle valve 'for engines comprising acasing, 'a valve stem within the casing, a valve at one end of the stem, a cup shaped member on the stem opening toward. the valve and having perforations near the bottom of the cup adapted to be closed by the casing, substantially as set forth.
2. In a valve mechanism, a unitary casing member having an entrance and an exit for iuid, said casing having a valve seat adjacent the entrance and an annular chamber adjacent the exit, a valve stem in the casing, apoppet valve thereon adapted to rest against said seat and a sleeve on the stem having an open end adjacent the poppet valve and havin in its sides openings adaptl ed to admit fluid to. said annular chamber when the poppet valve is unseat'ed, substantially as set forth.
3. In a. valve mechanism, a unitary casing member having an entrance and an exit for fluid, said ,casing having a valve seat adjacent the entrance and an annular chamber adjacent the exit, a valve stem in the casing, a poppet valve thereon adapted to rest against said seat and a sleeve on the stem having a closed end and vmeans adjacent the poppet valve to admit fluid to the sleeve and having in its sides a plurality of oppositely spaced openings at varying distances from its closed end adapted to admit iuid to said annular chamberin varying quantities when the poppet valve y'is unseated, substantially as set forth.
4. A throttle for engines comprising a casing, a poppet vaive for controlling the flow of steam through said casing,"a sleeve operable with the poppet valve andaffording at times a housing for steam, said sleeve being provided with a plurality of pairs of perforations, leach pair being on diametrically opposite sides of the sleeve, saidv casing formed withan annular chamber at all times completely surrounding the sleeve and adapted to form a passage for steam from a poppet valve interposed the sleeve when the perforations of the sleeve are brought into communication with the chamber, substantially as set forth.
l5. A throttle valve for steam engines-comprising a casing adapted to be connected to the boiler, a pipe leadinv to the engine, between said pipes, a sleeve with closed top operable with the poppet valve and provided with a pluy i vrality of pairs of perforations spaced along the sleeve, those of each pair being on diametrically oppositev sides of the sleeve'and in line with each other, said pairs of perforations being so arranged relative to the poppet valve that ithe pairs are brought
