Equipped with a flow control unit additional, flow sensitive expressions and accelerate sensitive expression shock absorber

摘要

(57) [summary] acceleration sensitive expressions buffer device, comprising a tubular housing, and a piston assembly within the housing, the piston assembly is divided into a chamber and the lower chamber of the upper housing. Piston assembly is connected to the wheels of the vehicle, the housing is connected to the chassis of the vehicle. Fluid can pass between the chambers above and below at a flow rate limited to the compression or stretching of the acceleration sensing type shock absorber. During acceleration in the downward direction of the wheels, the first port provides a fluid flow to the upper chamber from the chamber below. In order to increase the allowed to flow between the chambers, during acceleration in the downward direction of the wheels of the vehicle, movable inertial member of the piston assembly is allowed to open the port of first. When the fluid flows after the acceleration is reduced, the depression of the bottom of the inertial member is applied to the inertial member sufficient pressure to hold the open position of the port the inertial member. When you stop or decrease or acceleration of the wheels, fluid turning vane applies to inertial member sufficient fluid pressure to maintain in a closed position of the port the inertial member. Furthermore, the mechanical noise when pressure relief system and a pressure release valve for releasing the port from the recess, the fluid pressure in the recess is present, inertial member is moved toward the open position of the port I want to minimize.
