Patented July 21, 1936 pairs!) STATES commmsson Wade H. Wineman, Michigan City, Ind., assignor to Sullivan Machinery Company, a corporation of Massachusetts Application September 29, 1934, Serial No. 746,169 10 Claims. (01. 230-108) My invention relates to gaseous fluid compressors, and more particularly to gaseous fluidc'ompressors in which a liquid is employed under the action of centrifugal force as the gas compressing medium.

From one of its aspects my invention relates to the provision of a gaseous'fluid compressor in which a liquid, after having had a large amount of energy imparted to it in the course ofits action as the compressing medium and while, furthermore, under the pressure existing at the discharge side of the compressor, is so handled as to cause the same to give up its energy, and to impart the maximum available energy to the driving system for the compressor. From another aspect of my invention the same comprises the feature of employing in a liquid compressor system a separating device in conjunction with the compressor of such nature thatthe kinetic energy of the liquid flowing from the discharge side of the compressor is largely preserved and I made available for delivering work to the driving system of the compressor. From still another as H pect my invention comprises the employment, in

aliquid compressor system, of a very effective air separating mechanism which, like the compressor, operates upon the centrifugal principle and which preserves and makes available energy pres- I v ent in the liquid when it enters the separator.

' An objectof my invention is to provide-an improved fluid compressor. Another object of my invention is to provide an improved fluid compressor of the centrifugal type. Still another object of my invention is to provide an improved fluid compressor of the centrifugal type having improved compressing-liquid handling means incorporated therein. Still another object of my invention is to provide an improved combination of a hydraulic centrifugal compressor and 'an improved hydraulic separator. Yet another object of my invention is to provide an improved combination of a hydraulic centrifugal compressor, a centrifugal separator, and a hydraulically-actuated power economizing device for the compress'or drive. Other objects and advantages of my invention will hereinafter more fully appear.

Referring to the drawings, it will be observed that a base I is provided in the form of a large hollow tank in which water 2 or other suitable compressing medium is employed. Desirably, a 15" suitable cooling means in the form of a radiator or the like immersed in the water may be provided, or the water in the tank can be changed if that be found more practicable. Upon the tank I there is mounted upon a suitable support 3 2'0 2. driving motor 4, herein an electric motor, and in alinement with the motor there is mounted a. compressor 5 of the hydraulic, centrifugal type. The motor shaft 6 is connected through a suit- I able flexible coupling 1 with the shaft 8 of the 25 compressor, and the latter carries a rotor 9 which is provided with a series of generally radially extending passages l0, II at oppositesides of a central fin member [2. The passages ll" conmiunicate with an annular intake space H to which 30 air or other gas to be compressed is admitted through a suitable connection IS. The passages I!) are adapted to be supplied with a liquid (herein the water from the tank I) from a supply chamber l6 which communicates with a supply 35 space I! connected by a suction pipe l8 with the interior of the tank I. Suitable means for priming the pump may be employed in starting it up, if desired or needed. The passages lll'and H unite in a circumferential zone 20, the fast mov- 40 ing liquid drawing in the air through the passages I I, and the mixture, with the air duly compressed being discharged into a stationary raceway 2l which leads to the point of compressor discharge. The zone 20 may be annular or broken 45 up into a series of chambers extending radially and communicating with the spaces ill and II at their inner sides and with the raceway 2| at their outer sides. From the raceway 21 a connection 22 leads tangentially into the upper portion of 50 a centrifugal separator chamber 23 in which, under the action of centrifugal force, a very complete and effective separation of the entrained and compressed air from the compressing medium takes place. The liquid within the chamber 55' 23, shown at 24, whirls rapidly around within the chamber and is permitted to return from the bottom of the chamber through a connection 25 formed to conserve the velocity of the liquid, to, a nozzle element 26 in the same horizontal planes with the lower portion of a Pelton wheel 21, which is secured to an extension 28 of the compressor shaft 8. The buckets 29 of the Pelton wheel are acted upon by the liquid'dischargingthrougfithe nozzle 26, so that'the wheel aids the motorin' cf fecting drive, as it were, and thereafter the liquid, falls into a sump 30 and returns through a coi'r' nection 3| to the tank I. The liquid level separator 23 can obviously be controlled by the use of suitable manual or automatic val es, ittlesired, but it is evident thattlre liquid can"pass-' out of the chamber at least as rapidly as the mixture enters, and since the Pelton wheelis own, smaller radius than the orifices at the periphery, of the compressor rotorthe liquid dischargeve y-w i amp y-h h s w The -modest operation-of my; proved conipressor mechanism will be readily understood fromyvhat has been said with respectto itsoonstruction.
