The present apparatus is intended for measuring water and other liquids a lessening of the friction of the moving parts, thereby reducing its mode of action becomes reliable and accurate.

In the accompanying drawing is:

Fig. Ι a Grundrifs of the Mefsapparates, but the head lock is removed.

Fig. 2 is also a plan with the piston in a different position as in Fig. 1.

FIG. 3 is a cross section on line xx of FIG. 1.

Fig. 4 is a cross section on the line yy of Figs

Fig. 5 is a perspective view of the Mefsapparates, wherein the Kopfverschlufs as in Fig. ι and 2 is removed.

The body A of the Mefsapparates is cylindrical in shape, as shown in the drawing, and provided with a flange which runs around the upper edge; The head lock A ^{1 is} fastened to the flange with bolts. The interior of the cylinder is divided into three chambers B, B ¹ and J5 ² , from which the main chamber B is separated from the inlet chamber B ¹ and the outlet chamber B ' ² by a transverse partition C. With the inlet chamber B ^{1 there} is a feed pipe b ¹ in a suitable manner. connected and the outlet chamber provided with an outflow pipe b ' ^2.

The inlet chamber B ¹ is connected to the bottom and top closures A ¹ with the main chamber B by means of passages or openings HH, FIGS. 1 and 3, and the main chamber B with the exit chamber B ^{2 by} means of similar passages H ¹ H ¹ , FIG. 1 , 4 and 5. In order to make the flow of water more regular, guide ribs h should be installed in the passages HH.

Where the main chamber side of said partition C are mounted incisions ii near the Einlafsöffnungen HH, as shown in Fig. 5 shown most clearly, and, close to be located at the Auslafsöffnungen slightly wider incisions / 2 'ή ¹ ,, in which the Reach the outlet openings for the purposes set out below, Fig. 5. ·

In the middle of the cylinder there is a fixed pin D around which a square hub E can rotate freely; to the latter is attached the piston G, which is provided in the middle with an elongated coulisse g , the outer ends of which are rounded, so that the piston with the hub. make half a turn in the direction of the arrow, as indicated in FIG. 5, and then slide freely in the longitudinal direction on the hub from the position indicated in FIG. 2 into the position indicated in FIG. 1. The upper end of the hub E is slotted at e , Figures 4 and 5, for receiving the coupling at the lower end of the shaft F which passes through a stuffing box in the cover A ¹ and engages the usual registration mechanism.

At each end of the coulisse g there is a recess K i in the flask. which, when this end of the piston touches the hub, forms a small space, open at the top and bottom, around which the openings H ₁

Claims (1)

FIGS. 2 and 4, to receive incoming water when the piston is the one indicated in FIG Location reached. In each side wall of the piston openings are // (I ¹ J ^1), Fig. 3 and 5, mounted which, when the piston reaches the position shown in Fig. 1, a connection between the EinlafsöfFnungen HH and the incisions ii in the Make the front surface of the partition C. Provided that the piston is in the position shown in FIG. 1, the water passes through the openings HH and will fill the interior of the coulisse g in the piston; the water then passes through the openings // to the incisions ii behind the piston and exerts such a pressure here that the piston rotates in the direction of arrow 1, Figs. 1 and 5, while the water moves with the advancement of the piston through the openings H ¹ H ¹ escapes. When the piston has reached the position shown in Fig. 2, the water entering will pass through the apertures H to the recess K between the piston and the hub E, and since the Coulisse on the other side of the hub to the Ausflufsöffnungen H 'H ^{1 is} open, the water pressure will drive the piston at the hub E across the chamber from the position shown in Fig. 2 to the position of Fig. 1, whereupon the first described movement of the piston is repeated. A rotation of the piston through a certain angle thus alternates with a rectilinear movement of the same, from which a discontinuous rotation of the hub E results. This is transferred to the registration device. Since the piston G is kept almost in equilibrium in all positions, and since the hub E prevents the piston from resting firmly against the circular wall of the chamber B during its rotational movement, there is comparatively little friction, which is why the measuring apparatus is also very low weak prints will work fine. The incisions h ^l in the part C to the Auslafsöffhungen let the water in front of the piston rapidly escape and allow the piston to execute its half turn and get to the partition C before the beginning of the rectilinear motion to close. In the case of large measuring apparatus, it is preferable to make diagonal passages / m, Fig. 2 and 4, on the inner sides of the lid part A ¹ and the base plate, as a substitute for the passages / J and / ¹ J ^{1, in} order to allow the water to flow out the interior of the piston to get to the slots ii behind the same in order to bring about the rotary movement of the piston. Referring to Fig. 6, there is shown a modification of this invention. The piston is slightly narrower here, the housing has a projection P with a arcuate recess which is concentric with the rounded end of the piston, so that more extensive sliding surfaces are produced for the latter during its back and forth movement making the movement of the piston safer and preventing leakage will. Patent claim: A water knife in which a coulisse-like piston (G) is rotated 180 ° around the axis of rotation of a rotatable coulisse slide (E) and then pushed back straight into the starting position by the pressure of the liquid supplied between the piston and slide. 1 sheet of drawings.
