Abstract:
A throttle device for installation between a cylinder of a hydraulic adjustment device having a housing and a cylinder interior and a hydraulic line for establishing a throttle resistance to a flow of hydraulic fluid in at least one of two opposing flow directions, said throttle device comprising:a disk having a passage movably mounted in a movement space arrangeable in said hydraulic line, said disk and said hydraulic line being configurable for forming a channel between said disk and said hydraulic line when said disk is arranged in said hydraulic line;a first stop for preventing movement of said disk past said first stop in one of said two opposing flow directions;a second stop for stopping movement of said disk in the other of said two opposing flow directions, wherein said disk is movable between a first position whereat said disk abuts said first stop and a second position whereat said disk abuts said second stop; anda widening at an end of said passage directed toward one of said first and second stops for reducing a flow noise of the fluid at high flow speeds, wherein said widening comprises a first widening directed toward said first stop and a second widening directed toward said second stop, each said first and second widenings comprising a funnel-shape and wherein said first and second widenings are identical.
