Abstract
440,989. Ejector pumping-apparatus. FREITAG, F., 34a, Stampfenbachstrasse, Zurich, Switzerland. May 13, 1935, No. 13969. Convention date, May 12, 1934. [Class 71] In a water - jet pump, a resistance body W is placed at the end of the delivery nozzle b to increase the pressure of the liquid and to ensure the pump functioning when the supplywater pressure is low. A vacuum chamber surrounds the inlet pipe a and the delivery nozzle b, and the connection d for the vacuum is arranged near the inlet a. Removable rings k may be provided to facilitate engagement with the water cock. The body W may consist of layers of metal braid secured by a ring or by a collar secured to the chamber c. In the construction shown in Figs. 3, 4, the resistance comprises a guide piece o which divides the water jet into a number of streams. Beyond o are arranged layers of metal braid housed in a bushing p with a prolongation s which may be pivotally connected. The pump is secured to the cock by a cap t<1> which receives a nut w<1> adapted to engage a conical rubber ring k<1>. A protecting disc y<1> is provided. In a modification, an elastic disc and set-screws are used. In a further modification, the pipe a is integral with the chamber c into which is screwed the nozzle b.
