AIR-COMPRESSOR VALVE.
Application filed .rugust 13, 1921. Serial No. 491,988.
To all whom it may concern:
Be it known that l, HENRY E. Pnnnn'rinm a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Air Compressor Valves, of which the following is a specification.
The principal obj ect of this invention is to provide a practical and efficient spring operated conical seated air valve and means combined therewith expediting its rapid closure when in operation.
Another object is the means provided within an air valve for lubricating the moving surfaces and preventing the valve spring from rusting.
A third object relates to the peculiar conformation of the plunger for rapid venting of the valve and holding it against its seat when closed.
These and other objects are attained by the novel construction and arrangement of parts hereinafter described and shown in the accompanying drawing forming a material part of this disclosure and in which Figure 1 is a partial sectional view showing the outlet valve assembled and in closed position.
Figure 2 is a transverse sectional. view taken on the line 22 of Figure 1.
Referring to the drawings in detail, the numeral 10 designates a fragment of an air compressor cylinder, having a head 11 and a cylindrical compression chamber in which a reciprocating piston of conventional type normally operates. Formed partially through the cylinder head 11, at a spaced distance from the center of the cylinder, longitudinally of the center line of the compressor, is a bored cylindrical opening 12 its inner end terminating in an angularly restricted opening 13 communicating with the compression chamber 14 and forming a conical seat for the valve 15.
The outer end of the opening 12 is provided with screw threads adapted to engage the valve cap 16, its outer portion being squared to receive a wrench for tightening and in the opposite end, concentric with the threaded portion of the cap is a drilled hole 17. Reciprocatively slidable within the opening 12, by the action of the compressor piston is a cylindrical bodied valve plunger,
generally designated by the numeral 15 comprising a conic-a l bevelled flat pointed plug end i8 suited to the seat 13, adjoining which is anarrow cylindrical surface 15) leading to the lower edge of an annular groove 20 its arcuate cross section having a relatively large area, preferably approximating one fourth that of the valve body.
A drilled hole 21 is concentric with and extends into the body 15 from its upper end and is counterbored approximately one half its length, forming a reservoir 22 for holding lubricating oil.
The valve plug end 18 is held in normal engagement against the seat 13 by the pressure of a helically coiled compression spring operatively confined within the holes 1. and respectively of the cap 16 and the valve 15, the oil maintaining the spring well lubricated and tending to prevent crystallization.
in outlet or exhaust port 25 passes through the wall of the compressor 10 at a right angle to the valve chamber 12 and its axis is in approximate alignment with the outer edge of the groove 20 when the valve is in a closed position, and fitting the screwthreaded port 25 is a pipe 26 leading to a reservoir for air passed from the compressor through the outlet valve as described.
In operation such valves move at'a rapid rate, at a high frequency, and in order to attain their greatest efficiency, must close at the instant the compressing piston has completed its full stroke; this is partially accomplished by the compression spring, the effect of which is materially au mented by the air pressure blast from the reservoir. back through the pipe 26, impinging on the lower portion of the annular groove 20 and acting to effect instantaneous closure of the valve when pressure is removed from its end exposed to the cylinder, this being the purpose of the groove and its relative position with respect to the outlet.
From the foregoing it will be seen that a simple device for this purpose has been disclosed in the preferred form of its embodiment, but it is not desired to restrict the details to the exact construction shown, it being obvious that changes in shape and proportion, not involving the exercise of invention may be made without conflicting with the scope of the appended claim.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
A cylindrical valve plug, operable Within a chamber, cone shaped co-operative elements integral With said valve and said chamber, spring means for closing said valve, a recess formed in the valve plug adapted to hold a lubricant, preventing rustingof the spring and automatically lubrieating the valve, an. annular groove of arcuate cross section formed in said valve plug adjacent its conical portion, and a port in said chamber, the center of said port being in a plane approximately level with the upper edge of said groove when the valve plug is against its seat.
This specification signed and witnessed this 12th day of August, 1921.
HENRY E. PELLETIER.
