Title: Apparatus for synchronizing a pair of co-operating piston motors
IPC: F01B17/02
Filed: 1958-04-23
Abstract: 871,892. Hydraulic systems. KOPPERS G.m.b.H., HEINRICH. April 23, 1958 [May 25, 1957], No. 12930/58. Class 69 (2). Synchronous operation of a pair of parallel connected motors is ensured by supplying liquid to the motors through a common balancing valve and passing the exhaust from the motors through a second balancing valve. For a stroke in one direction liquid is supplied through a line 13a and balancing valve 10a to lines 11a, 12 leading to motors 1a, 1. Exhaust from the motors passes through lines 11, 12a and a valve 10 to a line 13. If, say, motor 1a is loaded more highly, the piston of motor 1 will tend to move more quickly and the pressure of the exhaust liquid in line 11 be greater than that in line 12a and will act on a central partition 18 of the control member 17 of the balancing valve 10 so that the member 17 is moved to the right to partially cover a port 21 and thus throttle flow of liquid from line 11 which takes place through an axial bore in member 17, ports 19, an annular tapered recess 20a and port 21 to a chamber 23 open to line 13. For a reverse stroke liquid is fed through line 13 and exhausted through line 13a, and balancing valve 10a ensures synchronous operation of the motors. Relief valves 27, 27a are associated with each balancing valve.

Title: Improvements in fuel supply systems to jet propulsion engines mounted on the wings of rotating wing aircraft
Inventor: SIMMONS HAROLD CUTHBERT
IPC: F02C7/232

Abstract: 732,918. Jet propulsion plant. DOWTY EQUIPMENT, Ltd. June 3, 1953 [June 3, 1952], No. 14000/52. Class 110 (3). In a fuel-supply system for the burners of jet propulsion engines mounted at the tips of the wings of rotating-wing aircraft in which fuel is fed to the burners from a pump through a rotating joint and along fuel conduits mounted in the wings, each feed conduit has, at the end adjacent the wing tips, a pressure-reducing valve which is loaded in the closing direction by a mass the force on which varies with the centrifugal force due to the rotating wing. The fuel to ram jet units mounted at the end of'the wings of a rotating-wing aircraft is supplied by a pump through a control valve, a rotating joint and feed conduits 22 arranged parallel to the leading edge of the wing. To avoid, variations in the fuel pressure due to variations in speed of rotation of the rotating wing, pressure-reducing valves 23 are arranged in the conduits 22 at the wing tips. The conduits 22 are bent back on themselves to provide valve seatings 24 with which valve closure members 25 co-operate. The valve closure, members each comprise a half ball member 25 engaged by a: spherical mass 26 which is guided in a cylinder 27. A light spring 28 is provided to keep the conduit 22 upstream of the valve primed. The centrifugal force on the mass 26 opposes the increase in fuel pressure also due to centrifugal force so that the pressure downstream of the valve will be substantially the same as that of the pump delivery. If desired, the mass 26 may act on the member 25 through a lever system. Instead of using a rigid mass a column of liquid of the same density and length as the column of fuel in the conduit 22 may be employed.
