Abstract
A strut includes a first end, a second end, a cylinder and a piston, wherein the piston is mechanically coupled to the first end and the cylinder is mechanically coupled to the second end. A fluidic chamber is formed between the cylinder and the piston. A first fluidic passageway fluidly couples the fluidic chamber and a fluidic reservoir, and a second fluidic passageway fluidly couples between the fluidic chamber and the fluidic reservoir. A check valve includes an open-biased moveable valve element coupled to a balance spring, and the valve element interacts with a valve seat to control fluidic flow through the second fluidic passageway. The valve element is responsive to urging of the balance spring.
