WING PUMP.
Application filed May 11, 1925, Serial No. 29,494, and in Norway May 16, 1924.
The present invention relates to wing pumps of the kind wherein several pump chambers are connected with common suction and pressure channels with, common valves. Hitherto each set of associated chambers were mutually connected through channels arranged in the cylindric pump casing, butin this construction the channels had a great length, and the casing had to be made with a comparatively great diameter, resulting in a great total weight of the pump.
I have discovered that the said connecting channels can be arranged within the hubs of each wing set which gives very short channels and a small total diameter of the pump, consequently a small weight. Further I can arrange each set of common valves in a separate intermediate piece clamped between the flanges of the casing and those of inlet and outlet, thereby enabling an easy and cheap manufacture and inspection of the valves, seats, etc.
In the annexed drawing:
Fig. 1 is a longitudinal section of the pump.
Figs. 2 and 3 are cross sections substantially on the lines IIII and III-III respectively of Fig. 1.
The cylindric pump casing 1 is provided with a removable cover 2. Within the easing are four stationary wings 3, connected together by the hub 4 and four movable wings 5, connected together by the hub 6, attached to the central shaft 7. Hub 4 is idly surroundin said shaft. The pump shown is 8-fol acting.
If the wings 5 are moved in the direction of arrow 8, pressure will be created on the forward side of all four wings 5 and a corresponding suction is created on the rear side. The fluid to be pumped is consequently sucked in through valve 9, arranged in the intermediate piece or plate 10 and enters the four suc ing chambers connected together through the channels 11 within hub 6. Simultaneously the fluid is pressed out from the four pressure chambers, connected together by the channels 12 within hub 4, passing to the outlet through the valve 13 arranged in the intermediate plate 14. During the return stroke of the wings 5 the fluid is sucked in through valve 15 and is pressed out through valve 16 as will be easily understood from the drawing. The piece 10 carrying the valves 9, 15 and their seats may be easily taken out, and the same obtains as to piece 14 with valves 13, 16. 0
The drawing shows a pump with four pairs of wings; but of course I can use another number of pairs.
Claims 1. In wing pumps, the combination of a pump casing having internally a 'cylindric shape, a movable shaft centrally in said ca-zing, two hubs inside the casing one surrounding the shaft loosely and bein stationary in the casing, whereas the other is fixedly connected to and movable with the shaft, angularly equally spaced stationary wings in a number higher than two arranged between the stationary hub and the cylindric casing wall, channels in said stationary hub interconnecting the spaces between the appertaining wings. a number of angularly equally spaced wings fixedly connected to the movable hub between the same and the cylindric casing wall, channels in the movable hub interconnecting the spaces between the appertaining wings, and valves arranged outside the pump casing to control the two sets of chambers formed between the stationary wings and the movable wings.
2. In wing pumps, the combination of a pump casing having internally a cylindric shape, a movable shaft centrally in said casing, two hubs inside the casing one surround ing the shaft loosely and being stationary in the casing, whereas the other is fixedly connected to and movable with the shaft, angularly equally spaced stationary wings in a number higher than two arranged between the stationary hub and the cylindric casing wall, channels in said stationary hub interconnecting the spaces between the appertaining wings, a similar number of angularly equally spaced wings fixedly connected to the movable hub between the same and the oylindric casing wall, channels in the movable hub interconnecting the spaces between the appertaining wings, a pump inlet, two valves one arranged between the common inlet and one set of chambers formed between the stationary and movable-wings, the other valve arranged between the inlet and the other set of chambers, said valves openin inwardly from the inlet, a pump outlet, and two valves one arranged between the common outlet and one set of said chambers, the other valve between the outlet and the other set of chambers, the last-mentioned valves opening outwardly to the outlet.

4. In wing pumps, the combination of a pump casing having internally a cylindric shape, a movable shaft centrally in said easing, two hubs inside the casing one surrounding the shaft loosely and being stationary in the casing, whereas the other, is fixedly connected to and movable with the shaft, angularly equally spaced stationary wings in a number higher than two arranged between the stationary hub and the cylindric casing wall, channels in said stationary hub interconnecting the spaces between the appertaining wings, a similar number of angularly equally spaced wings fixedly connected to the movable hub between the same and the cylindric casing wall, channels in the mov able hub interconnecting the spaces between the appertaining wings, a pump inlet, two valves arranged on a separate intermediate piece outside the casing, one between the common inlet and one set of chambers formed between the stationary and movable wings, the other valve arranged between the inlet and the other set of chambers, said valves opening inwardly from the inlet, a pump outlet, and two valves arranged on a separate intermediate piece outside the easing, one arranged between the common outlet and one set of said chambers, the other valve between the outlet and the other set of chambers, the last-mentioned valves opening outwardly to the outlet.
