Title: Fuel tank
Inventor: INATOMI TAKEO
IPC: B60K15/03
Filed: 1992-06-24
Abstract: PURPOSE:To withstand impact without increasing the strength of the side wall of a fuel tank so as to make the fuel tank lightweight by providing an impact damper for absorbing the inertia of fuel to relax impact, on the tank side wall inner surface upon which impact load acts. CONSTITUTION:An impact damper formed of an air bag 6 is fitted to the front face of a fuel cell 4, in contact with the inside of the front wall 2 of a metal tank 1. As a result, in the case of impact load at the time of forced landing or the like acting frontward upon the fuel tank, the inertial force of fuel is caught by the impact damper formed of the air bag 6 so as to lighten the impact load acting upon the front wall 2 of the metal tank 1. In the case of being shot by a missile or the like, the pressure of fuel is instantaneously heightened since the missile advances rapidly in the fuel cell 4, but the impact force is relaxed, and the damaged area is reduced.

Abstract: PURPOSE: To allow air to effectively escape and to prevent fluid leakage by bringing down a bore of a body member of an air vent passage opened to a first fluid chamber, sideways by a specified angle to change its direction to a horizontal plane. CONSTITUTION: A tensioning device 400 for imparting appropriate tension to a chain or a belt accommodates a plunger 44 slidably in a bore 38 of a body member 36 and makes a pressurized fluid flow into a chamber 40 to impart tension to the chain or belt by the plunger 44. An air vent passage 48 is opened to the chamber 40 near the closed end of the bore 38 with such position relation that the tensioning device 400 can be brought down sideways to change its direction to a horizontal plane as long as the air vent passage 48 maintains inclination greater than zero to the horizontal plane so as to allow entrapped air to escape from the chamber 40 through a restriction 51 and to prevent a fluid from leaking out by gravity at the time of being pressurized. Air can therefore escape at the time of filling a fluid in the device and during operation.
