I piston headiO' hy forming the bodyl of the piston of a'central portion 11a' with radially disposed supporting Yanes 11b, herein shown 1n theshape of a cross inl Figs. 1,2 and 3., I n this mannerv the 'body of the piston is .lightenedconsiderably.l It willzbe seen that. I have replaced' the customary'ducted cylin-I drieal piston with4 onev that iSv-lighter' and more. eiicient.
The inletsuction valves 9 shown-in Figs.
vvHerein I have shown each suction vulve as comprising theyalve 'member 12,;the lseat 13', the annular chamber 4141C belovvithe-seat, theigui'des 15', the hollow cylindrical valve lways ofthe piston through the'h drieal. stem," valve' i p the annular'chamber valveto From the Hforegoing it Will be understood vthat the valve members 12h`ave -a reciproca- 'tory motion which isthe reverse of the piston motion: Suitable means 'are provided to limit this motion upon the. suction stroke, as
`for example, pins 1 8'wli-ich are carried b v the piston ,head 10 and' which extend mein'bers 12. The pins in turn are held `against endwise movement by vsuitable means such as by'one of the piston rings 20 shown andf'a'ehamher 21 is formed. A depending wall or partition 22 divides this Chamber 'into two communicatingchambers 21" and 21", the former communicsrling with the inlet .pipe 1 andthe latte;` oommunicatin f the ports 8 in the'cylinderwalls. T e gas is supplied by the inlet pipe and passes suc! cessively through' the chambers 21 and 21, the'fports 8, the piston 3 and the suction valves 9 into the Cylinder. In the working -cycle of the refrifgerating fluid, vaporiznwith tion is. generally; 1ncomplete, and the re- `turning vapor issaturated to a greater or less .degree with liq`uid. The returning .saturated vapor` frequently carries scale from'the pipmg system. When the vapor asses from e supply pipel into the chamer 21' it impinges'upon the depending wall 2.2 and the/ liquid. and the scale are tprecipin tated from the vapor to thewall an subsequentlyto the bottom-of the chamber. The
vapor meanwhile passes the barrier and. is supplied to the ovlinder through the port opening' 8. in rhalnher l eansrs the latter lo act as a Iaction trap ior lh'e eoinpressor, the trap shown herein being proportioned to have a volumetric eapaoitlv capable of Vonoe oompletel)v iilling eaeh cylinder.
l 'laini as my invention:
1. ronlpri-issor having, in combination, a Cylinder having,r an inletportpa 'piston rompriaing a head. portion. andl a body portion ha ving` a central portion and a plurality of'iadiall'v disposed vanos forming renti-al angles, and inlet valves in said head portion :dined with the' central angles delined liv sa id vanos wlnirehy a direetarnl nnobslrni-led pase-age is provided from said port lo each oi said valves.
.2. A compressor havil'ig, in eomliimitioif. a cylinder having' an inlet port` a, pistw romprisinna head portion and a eroe-v. shaped body portion. and inlet valves in Hai. head portion alined` with the quadrante ditined b v said body portion whereby a direrf and unobstructed passage is provided frol,I
said port to each ot said valves.
3. A compressor having, in eon'ilnnation. a piston, an inlet ein-tion valve in Sil-id piston. a pin in thepiston.extending loosely through said valve for limiting:l the reciprocz'ltorv -n'ioven1ent of said valve, and a pieton ring on said piston. for holdingA .ea-id pin in place 4.
