摘要： The device is especially intended for a pipe supplying a fluid which must be supplied, simultaneously or alternately, with another fluid. The device comprises a tank for a control fluid which surrounds the vertical supply pipe and in which a permanent magnet moves in accordance with the amount of control fluid contained in the tank. The magnet shifts a valve member inside the supply pipe so that the valve member closes the latter in one of the end positions of the magnet. The magnet is rigid with a float which freely extends around the supply pipe. The device can in particular ensure that fuel is supplied to an engine only if oil is supplied to the latter.

摘要： The invention relates to a proportioning pump for feeding at least two different liquids in a definite flow proportion. The pump has two interconnected displacement members executing their suction strokes and their delivery strokes simultaneously, each of which members is arranged in its own working chamber communicating with a suction and a pressure line by oppositely acting check valves. In accordance, with a particular application, this pump is employed in internal combustion engines with mixed lubrication for proportioning the fuel and oil, with the fuel-oil mixture being supplied to the float chamber of a carburetor.
