w. H. l LEINWEBER FLUID COMIRES SOR 'Filed Feb. 2, 1945 Patented Aug. 20, 1946 UNITED STATES PATENT OFFICE FLUID COMPRESSOR l William H. Leinweber, Chicago, Ill. AApplication February 2, 194,5, Serial No. 575,747 (o1. 23o- 172) 2 Claims.
My invention relates to improvements in compressors and more particularly to a hollow piston closed at both ends having inlet outlet ports in the sides of the piston and a compression chamber therein to give greater vaporization of iiuids.
The invention will be best understood by reierence to the accompanying drawing forming a part of this specification, and in which,
Figure 1 shows a longitudinal, central sectional View of a device embodying my invention.
Figure 2 shows a similar view of the same illustrating the piston in a differentV position and disclosing the three compression chambers for its thriple compression.
Referring in detail to the form of my invention illustrated herewith', I have shown a compressor cylinder I4 containing a thriple piston I5 and having a head I provided With a discharge valve 6 and an inlet valve 8.
These valves and cylinder construction maybe of any number or any type.
The bottom cylinder wall I6 has in its center a boss I Il in which piston rod I3 containing two piston rings 9 at the lower end is tted into boss I similar as a piston is fitted into a cylinder and works in the same manner therein, this arrangement prevents leakage of fluid or the like from entering into the crank case and thinning out the cil.
The upper threaded end of the piston rod I3 is screwed into boss I2 in the hollow piston I5 this arrangement gives perfect alignment at all times a more even stroke of the piston and piston rod in boss IU the efficiency is increased considerable for longer periods of time without repairs as no uneven wear to th'ese parts occur at anytime.
The hollow piston I has inlet and outlet ports II at the sides of the piston which `communicate through cylinder port 1.
The operation of the compressor described is as follows:
Viewing the compressor with its parts in the position shown in Fig. 2, in which position the air or iluid from chamber 5 has been expelled into chamber 4 of the piston I5, the piston I5 is in substantially its lowermost position, with a wall thereof closing the port of the inlet valve 8, which inlet valve 8 is of a construction which admits air or iluid into the chamber 4 or 5 under certain conditions to be hereinafterrnoted. As the piston I 5 moves upwardly, one of the ports of the lower ports II will register with the inlet valve 8 and a Acharge of air or iluid will be admited to the chamber 4. As the piston moves up, this charge or air or fluid. will be forced out ci' most position, a position adjacent the top wall I2,
the inlet Avalve 8 will communicate with' the chamber 5 below the piston I5 and a charge of air or iiuid will be admitted into the chamber from the inlet valve 8. As the piston moves downwardly, this charge of air or fluid from the chamber 5 will be forced through the ports l and Il into the chamber 4 of the piston I5, and when l the piston I5 reaches a point where one of the lower ports registers with the inlet valve 8, a charge of air or fluid will again be admitted to the chamber 4 of the piston. Thus, it will be apparent that the air or fluid compressed in chamber 5 being admitted through' the ports 'I and II into the chamber 4, is met with a charge of air or fluid through the inlet valve S, and this compressed air or fluid and the charge of air or iluid from the inlet valve 8 will then pass through the ports II and l into the chamber 3 where it will be re-compressed and expelled through the outlet valve 6. By this construction, it will be apparent that there are three stages of compression in the operation of the piston, the first stage being the compression of the air or fluid in chamber 5 and the expulsion of compressed air or fluid into chamber 4, where the compressed air or uid is bombarded by a charge of air or uid through the inlet valve 8. From this chamber 4, the compressed air or fluid is then admitted into the chamber 3 Where it reaches the third stage of compression and is expelled through the outlet valve 6. As before stated, the valves 6 and 8 may be of any approved construction, it being the intention that as to the valve 8, air or iiuid is admitted only into the chamber 5 and chamber 4 and escape of air or fluid is not permitted therefrom, whereas valve 6 is constructed to permit escape of air or fluid from chamber 3 but will not permit admission of air or fluid therein.
While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modication without departing from the spirit of the invention. I, therefore do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modification as come Within the scope of the appended claims.
Having thus described my invention, what ;I claim as new and desire to protect by Letters Patent is:
1, A compressor comprising a body providing a piston chamber, a piston in said chamber and providing on opposite sides thereof, together with said body,r compression chambers, said piston being of substantially lio-110W construction, means providing communication between the compression chamber on one side of the piston and and the compression chamber on the other side of said piston, and means for charging a, fluid to the interior of 4said piston chamber at a predetermined point in its movement within said cylinder.
thevinterior of said piston, means providing com munication between the interior of' said piston Y termined point in its movement within said cylindex, said last-named means including an inlet valve and ports formed-in said piston for communication with said valve.
