Title: Improvements in safety devices for fluid-pressure systems
IPC: F15B20/00
Filed: 1958-12-16
Abstract: 912,380. Flight training apparatus. GENERAL PRECISION Inc. Dec. 16, 1958 [Dec. 16, 1957], No. 40628/58. Class 4. Hydraulic apparatus for providing a sense of " feel " to a simulated control lever 78 in flight training apparatus comprises a piston-andcylinder loading device 50, 52 wherein the piston rod 54 is coupled to the lever 78 and the cylinder is provided with ports 56, 60 and 58, 62 respectively connected by pipes 64, 68 and 66, 70 to cylinders 26 and 28. The cylinders carry spring loaded pistons 42, 44 and are connected by pipes 22, 24 to a control valve 2. This has a spring-centred piston 4 and connections to a pressure liquid supply pipe 20 and an exhaust line 19. Movement of piston 4 is controlled by signals generated by a computer in the flight simorulat whereby when stick 78 is moved by the trainee valve 4 is simultaneously operated to transmit pressure liquid to the appropriate side of piston 52 to oppose such movement and give an appropriate sense of " feel." If, due to a fault in the system, valve 4 is operated so that piston 52 is driven violently one way or the other say to the right by application of abnormally high pressure liquid to the left face through pipes 22 and 64, movement of the piston will uncover port 58 thereby allowing high pressure liquid to enter pipe 66 and drive piston 44 to the right against spring 48 to close port 38 and thereby lock piston 52 and lever 78. In a further embodiment, Fig. 2 (not shown), cylinders 26 and 28 are associated with other cylinders wherein the admission of pressure liquid is metered to ensure operation of the safety cylinders 26 and 28 in response to rate of change of pressure difference within the system. The flow pipes may include metering orifices.
