The upper face 14 of the seat 10 is in this to seat a plurality of valves 16 overlying the ports 12. Each port 12 iscontrolledby a separate valve 16 each acting independently of every other valve.

zo aims.j(or.zv'v ]eo) J p v plate 21is mounted. The stopfipl ate 21 in'this instanceshas flat end faces and has anouter continuous edgeas shown at 22 across which plate 21, thedistance piece 18; and the seat 10 are rigidlyxheldtogether as by means of the screws 26.
.Thevalves 16 are of the voluntary type, that is, they are adapted tojbe raised from their seats by thefpr'essureof the fluid at the ports 12. They may-be returned to their seats by any suitable posed betweenthe bridging members 24'and the valves lficontacting with the former at approximately the center and bearing against thevalve 16 at the tips. The springs 28 are held in position of the spring in the notches of the distance piece 18. i
In the operation of the device shown in Figs. 1 to 6 the compressed fluid entering the ports 12 raises the valves 16 against the tension of the springs'28, 30 or 34 as the case may be, lift ing the valves bodily without essential bending, the amount of thelift being dependent upon the thickness of the distance piece 18. The motive fluidpassing the valves 16 passes through the valve assembly at the space betweenthe bridging members 24 and is discharged therefrom.
This form of valve assembly hasthe advantage that all of the pieces except the springs have fiat faces which can be easily machined and manufactured. The valves 16 are not adapted to bend and consequently have relatively long life. The faces of thevalves are easily machined, being flat to seatupon the flat face 14 of the seatlO and are relatively inexpensive.
The embodiment shown in Figs. 7 to 9 inclusive shows the valve assembly which is arranged to provide more port area than that above described. This arrangement includes a cage 50 generally cylindrical which is provided with a shoulder 52 to abut a corresponding shoulder 54 in a recess 56 of a compressor cylinder wall. A plurality of ports 58 are provided lengthwise of the cage 50 and on the interior of the cage are provided flat seats upon which are adapted to seat valves 62 similar to the valve 16. For each valve sep-.
To prevent the assembly from providing to o "much cylinder clearance the interior is partially filled by a plug 76 having a flanged end 78 to cooperate with a counter-bore '8'0 in-the cage 50.
The arrangement above described isarranged as an inlet Valve for a cylinder 82 of which the piston 84 is'partially shown as well as the cylin-.;
der head 86. In this instance the cage 50 fits into the aperture 56, of the cylinder wall and extends vacross the inletspace B8 and partially through the outer wall .which is closedaby a suitablecap 92enclosing. the valve assembly. The
valveassembly is held tightly in place'by a jack SCIBW'194: threaded. in the cap 92 and adaptedrto bear against the center of the rear vend:.of the plug" 76 at the intersection 960i the bridging.
Thus by the above construction are accomplished, among others, the objects hereinbefore referred to.
Iclaim: it
l. A valve -assembly comprising a cylindrical member having a plurality of ports arranged lengthwise therein, seats at the ports, rigid flat "plate valves cooperating with the ports, springs for holding said valves resiliently to the seats,
. separate distance pieces at the ends of each port mounted on said cylinder, of uniform thickness throughout and having notches to guide the valves only at their ends, and stop plates of uniform thickness throughout mounted on said distance Y pieces and arranged to confine the springs and the valves.
2. A valve assembly comprising a cylindrical member having a plurality of ports arranged lengthwisetherein, seats at the ports, rigid fiat platesv'alves cooperatingwith the ports, spring s for holding'said valves resiliently to'theseats; separate distance pieces of uniform thickness throughout mounted on said cylinder adjacent the ends 'ofeach port and having notches to guide the valvesohly at their ends,'st op plates of uniform thickness throughout mounted on said distance pieces and arranged 'to" confine the-s'prings' and the valves, and a spring clip on the periphery of the cylindrical. member for'holding'said cage in a compressor cylinder.

HARRY V. HAIGHI.
It is hereby certified that error appears in the printed specification of the above numbered patent requiring correction as follows: Page 2, lines 14, i5 and 16, claim 1, strike out the Words "at the ends of each port mounted on said cylinder, of uniform thickness throughout" and insert instead of uniiorrn thickness throughout mounted on said cyiinder at the ends of each port; and that the said Le ters Patent should he read with this correction therein that the same may conform to the record of the case in the Patent Office.
Signed and seated this 26th day of February, A. D. 1935.
