HIGH-SPEED PUMP.
SPECIFICATION forming part of Letters lPatent No. 725,814, dated April 21, 1903.
Application filed December 17,1901. Serial No. 86,190. (No model.)
To @ZZ whom, it may concorre:
Be it known that I, DONT BNKI, a subject of the Emperor of Austria-Hungary, and a resident of Budapest, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in High-Speed Pumps, of which the following is a specification.
My invention relates to high-speed pumps, and has for its object to so constructa pump that it will combine in operation the two conditions which are considered necessary for the practical success of a high-speed pump. One of these conditionsis that theY piston speed should be equal to or greater than the velocity with which the water streams through the valves of the piston, and theother condition is that the water should always flow in the same direction-that is, there should be no reversal of the direction in which the water iiows.
The invention will now bedescribed in detail with reference to the accompanying drawings and the features of novelty will then be' pointed out in the appended claims.
Figure 1 is a longitudinal section of a horizontal pump constructed according to my invention. Fig. 2 is a sectional elevation of a vertical pump embodying my improvement.
Fig.3 is a sectional elevation of a pump similar to that shown in Fig. 2, but having the reverse arrangement of suction and delivery chambers; and Fig. 4 is a longitudinal section showing a portion of the combined pistons with the adjacent parts drawn upon an enlarged scale.
The crank 4 drives the bucket-piston 3, re-
ciprocating in the cylinder l and provided with valves 2. Integral or rigidly connected with the said pistonare plungers 5 and 6. These plungers are practically of the same diameter, each of them being of a smaller diameter than thebucket-piston 3, and the difference between the cross-section of the bucket-piston and that of one of said plungers forms the effective working cross-section of the piston for both strokes. The two plungers do not contribute to the lifting or forcing action of the pump, but only diminish the working or effective cross-section of the bucket-piston. The plungers have guided movement in stuffing-boxes 9 and 10, arranged Within the suction and delivery chambers, respectively.
7 is the vacuum-chamber, and 8 indicates the air-chamber.
The stationary delivery-valves 11 are disposed in a circle in a cylindrical projection 14 of the stuffing-box 10. This projection is fitted closely to the pump-cylinder 1, so as to form with the bucket-piston 3 a closed annular water-chamber 15. A channel 12 is provided for draining the water which is forced through the stuffing-box 10, and a passage 13 serves to introduce liquid into the stuffingboX 9, so as to prevent the entrance of air.
When the-piston and plungers are moving from left to-right, (having reference to Figs. 1 andv 4,) water is drawn into the suctionchamber and remains in the chamber 7 until the next stroke. At the same time water will be forced by the bucket-piston 3 from the annular chamber 15 through the delivery-valves 11 into the chamber 8 and from the same tothe delivery-pipe. When the piston then moves from right to left, the delivery-valves will close and the valves 2 of the bucket-piston will open to allow the water to pass freely from chamber 7 to'chamber 15, it being understood that the bucket-piston moves through the water without propelling it. lt will thus be obvious that the stroke from left to right '.is both a suction and a delivery stroke, while thestroke from right to left is simply an inactive return stroke. The water thus always flows in the same direction-that is, from left to right in Figs. l and 4and owing to the absence of a reversal in the direction of the water it becomes possible to operate the pump at a very high rate of speed.
It will be obvious that at the end' of the aotive stroke the water will have acquired a relatively high rate of speed and that in order to prevent a material checking of the water during the return movement of the piston the free passage area of the piston-valves should be at least equal to the eifective working section of the bucket-piston. In my construction this relation between the working or effective section of the bucket-piston and the size of the passage controlled by the piston-valves can be readily obtained, and thus my invention satisfies the second condition ICO for the practical working of a high-speed pump. It will be understood that the'plungers reduce the eective Working section of the bucket-piston and that by properly proportioning the size of the plungers and of the bucket-piston the effective working section of the piston combination may be made equal t0 or even smaller than the area of the passages controlled by the piston-valves. I have shown the suction-valves on thebucket-piston and the delivery-valves stationary; but instead of this the suction-valves might be stationary and the delivery-valves arranged on the piston. It will be understood that the operation of myinvention is the same Whether the pump is horizontal, as in Fig. l, or vertical, as in Figs. 2 and 3.
What I claim as new, and desire to secure by Letters Patent, is-
l. In a pump of the character described, the combination of a casing, a pump-cylinder, a bucket-piston Iitted in said cylinder, two plungers of substantially equal diameterconuected with said bucket-piston and arranged 0n opposite sides thereof, stuffing-boxes in which said plungers are adapted to work, and suitably-disposed valves,substantially as and for the purpose specified.
2. In a pump, the combination of a casing, a pump-cylinder, abucket-piston fitted in said cylinder, two plungers connected with said bucket-piston and arranged on opposite sides thereof, stuffing boxes arranged in said pumpcasing and adapted to receive said plungers, and valves carried by said bucketpiston. y
3. In a pump of the character described, the combinationof a casing, a pump-cylinder, a bucket-piston fitted in said cylinder, two plungers of substantially equal diameter connected With said bucket-piston and arranged on opposite sides thereof, stuffing-boxes 1ocated in the pnm'p-casingand adapted to receive said plungers, and valves carried by said bucket-piston.
4. In a pump yof the character described, the combination of a casing, a pump-cylinder, a bucket-piston fitted in said cylinder, two plungers of substantially equal diameter connected with said bucket-piston and arranged on opposite sides thereof, staining-boxes located in the pump-casing and adapted to receive the plungers, an annular chamber or casing adjacent to the pump-cylinder, and delivery-valves located at the said annular chamber and encircling one ot' said plu ngers.
In witness whereof I have hereunto set my hand in presence of two witnesses.
