Abstract: 326,025. Benes, J. March 12, 1929. Air, removing; multiple-delivery piston pumps; regulating delivery by by-passes.-A fuel pump for multi-cylinder internal-combustion engines comprises a pump barrel 28 and a differential plunger 2, 2<1> which draws the fuel from a chamber 25 through a valve 16 and delivers it through a passage 19 to an axial bore 20 in a rotary valve 8<1> which distributes it successively through a passage 23 to a number of pipes 14, 15 connected to the engine cylinders. During the first part of the delivery stroke, the inlet valve 16 is kept open so that any air in the chamber 28 may return to the chamber 25. In the seat of the rotary valve are arranged two rotatable rings 10, 11 provided with chambers 35, 36 communicating by plungers 21, 22 with the bore 20 and by passages 35', 36<1> with the chamber 25.

The fuel then passes through the bore 20 and passage 23 to the pipes 14, 15. By moving the two rings 10, 11 together, the moment at which delivery begins is varied, and by moving one ring relatively to the other, as in Fig. 7, the quantity delivered is varied.

Abstract: 526,380. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd. March 14, 1939, No. 8214. Convention date, March 17, 1938. [Class 103(i)] A triple valve is adapted to give a two stage brake application by means of a regulating valve 12 controlled by brake cylinder pressure acting on a piston 15 the movement of which is opposed by fluid pressure acting on a smaller piston 23. The chamber below the piston 23 is charged from the auxiliary reservoir by a passage 28. When the brakes are applied the brake cylinder connected to a passage 6 is fed through restricted orifices 9, 13 after the valve 12 closes. An auxiliary load cylinder is also supplied with fluid through a passage 19 when the piston 15 is depressed. The load cylinder is exhausted by a passage 31 when the piston 15 is raised. A modification is shown in which the passage 31 is controlled by the slide valve. A groove 27 allows fluid to leak above the piston 23 and assist its downward movement when a gasket 25 leaves a rib 26 and also allows fluid to act below the piston 15 within a rib 20 in order to assist in lifting this piston.
