April 25, 1933. H. STEINER COOLING FACILITIES FOR ROTARY COMPRESSORS Filed Aug. 2, 1929 a L'L-- 'One end of the shaft 1 Patented Apr. 25, 1933 HANS STEINER, or WINTERTHfiB, SWITZERLAND COOLING FACILITIES non ROTARY coMPRnssoR-s Application filed August 2, 1929, Serial No.
This invention relates to improvements in the cooling devices of rotary compressors.
Rotary compressors, in which the stationary parts are cooled, including the casing and end covers, and-the rotary parts are cooled, comprising the rotor or piston and the shaft, operate at their greatest efficiency when there is the least amount of play possible between the housing and the rotor.
With the foregoing in mind it is the object of my invention to render the play between the parts independent of the varying working conditions of the compressor in order that the play may always be maintained at a minimum. I accomplish this object by providing means for separately varying the degree of cooling of the housing and of the shaft.
One embodiment of the invention is illustratively exemplified in the accompanying drawing, in which Figure 1 is a substantially longitudinal sectional view of a compressor equipped with the cooling means according to the invention; and Figure 2 is a longitudinal sectional view of a valve for controlling the flow of water to the rotor shaft. 7
Referring to the drawing, 1 denotes the rotary compressor comprising a cylindrical housing and end plates 1* therefor. The housing forms a water jacket having an annular water compartment 1 and the end plates 1 are provided with bearings in which a tubular shaft 1 of the rotor R is supported. is closed by a plug and provided with a pulley 1 beyond the adjacent bearing. The other end of the shaft 1 is open and receives a length of pipe 1 which is smaller in diameter than the bore of the shaft, and which projects into and axially of the latter to a point short of the plugged end thereof. A manifold housing 1 is carried by the bearing of the compressor housing 1 and is adapted to form a chamber over the open end of the shaft 1 to receive water being introduced into the shaft from the end of the pipe 1 and to lead it off through an outlet pipe 8 into a waste pipe 9. The water jacket 1 is supplied with water through a pipe 2 having a regulating valve 3 in the line to control the volume of water allowed to flow into the housing, the latter 382,912, at in Germany Angust 16,1928.
being provided with an outlet pipe 4 leading to a wastepipc 5. supplied to the pipe 1 through a pipe 19 which enters the manifold housing 1 along the axis of the compressor and joins the outer end of the pipe 1". with a control valve: 7 which receives its supply of water from apipe 6.
Figure 2 shows one example of how the valve 7 may be made-automatic.v Water supplied through a pipe 6 fiowsinto an annular space 16 and thence through ports 17 in a piston slide valve 18 into a pipe 19 leading to the cooling chambers in the rotor. A chamber 20 above thevalve 1.8 is connected by the pipe 21 with the main pressure conduit supplied by the compressor. When the air pressure in the main rises the valve 18 will be forced downwardly against the action of its spring 22. An increased area of the ports 17 is opened so that the supply of water is increased, as well as the cooling effect in the compressor. A rise of air temperature in the compressor is the result of an increase of air pressure; but since, as stated above, the cooling effect is proportionately increased the desired end is attained, namely there is no expansion of the rotor.
I claim 1. An arrangement for providing circulation of a cooling medium in the stationary and moving parts of a rotary compressor, comprising a water jacket housing for a rotor, a hollow shaft for the latter, means for supplying the cooling medium to the housing and hollow shaft, and means operativelyconnected to the supply means and compressor for automatically varying the quantity of cooling medium supplied by said first named means in accordance with variations in pressure of the air discharged from said compressor to reduce to a minimum the play between rotor and housing at all working conditions.
2. An arrangement,as claimed in claim 1,in which said last means comprises a valve having a casing provided with spaced chambers, one thereof being connected to the air line of the compressor and the other beingdisposed in the cooling line to the compressor, a slid- WVater is independently The pipe 19 is provided ing core between said chambers and adapted to open and close the passage through the chamber in the cooling line, and a spring for urging the core against the head of air in the air line.
3. The herein described method of regulat- V in g the circulatory cooling system of a rotary compressor, which consists in introducing a cooling medium separately into the stationmy and rotary parts of the compressor, and
in utilizing the variations in pressure of the air discharged from the compressor to automatically vary the quantity of the cooling medium in the rotary parts of the compressor to reduce to a minimum the play between rotor and housing at all working conditions. r
4:. A cooling arrangement for a compressor comprising a Water jacket housing for a rotor, a hollow shaft therefor, means for independently supplying Water to the housing and shaft, valves controlling the Water supply to the housing and shaft, the valve controlling the Water supply to the shaft being controlled by the pressure of compressed air produced by the rotor, whereby the flow of the Water passing through said last mentioned valve is increased upon increase in pressure of the air discharged by the compressor and vice versa, to reduce to a minimum the play between rotor and housing at all Working conditions.
In testimony whereof I aflix my signature.
HANS STEINER.
