Abstract
A variable valve for impact dispersal of a force, such as a force caused by an impact or explosion. The apparatus includes a valve with a spring biased piston that engages an outlet bore as the piston moves in response to the pressure of a fluid at an inlet port. The valve is in fluid communication with a cylinder that receives an impulse force. The fluid flow from the cylinder is controlled by the variable valve, which disperses the force accordingly at a controlled rate. In one embodiment, a pressurized reservoir is connected to an extension valve and a check valve that allows the cylinder to be filled with fluid from the reservoir when the extension valve is actuated. Applications for such a system include connection to aircraft seats and to aircraft landing gear.
