Abstract

770,452. Apparatus for testing hydraulic systems. HAMILTON MOTORS (LONDON), Ltd. Nov. 2, 1955 [Aug. 6, 1954], No. 13313/54. Class 69 (2). Apparatus for testing aircraft hydraulic operating and control systyms comprises displacement type pumps C ... C<SP>3</SP> delivering through lines E ... E<SP>3</SP> and non-return valves E<SP>5</SP> to a delivery line E4. By-pass valves F ... F<SP>2</SP> enable pumps C ... C<SP>2</SP> to be selectively bypassed, and a valve F<SP>3</SP> enables all the pumps to be by-passed. The line E<SP>4</SP> terminates in a coupling by which it may be connected to the hydraulic system to be tested, and the pressure in the line is maintained constant by a valve K at a value determined by an adjustable setting device K<SP>1</SP>. A metering valve J, the pressure drop across which is maintained constant, is disposed in a by-pass between the delivery line E<SP>4</SP> and an exhaust line G, and, in conjunction with the valves F ... F<SP>2</SP> enables any rate of flow between zero and the combined output of all the pumps to be obtained. The exhaust side of the system under test may be connected to a reservoir D or directly to an inlet line D<SP>1</SP> of the pumps. The valves F ... F<SP>3</SP> incorporate safety valves, and a cooling device N may be provided.
