Title:
HYDRAULIC SHOCK ABSORBER
Document Type and Number:
Japanese Patent JPS61116136
Kind Code:
A
Abstract:
PURPOSE:To make a feeling of driving comfortableness yet improvable, by making up an outer circumferential from into a drum type, while preventing the occurrence of sticking in time of piston's sliding motion and thereby improving its slidability so better. CONSTITUTION:With an increase of pressure in an A chamber in time of stretching processes, a skirt 26a receives oil pressure and is deformed to the side of a cylinder 1, and in time of contracting processes, with an increase of pressure in a B chamber 5, a skirt 26b is deformed to the side of the cylinder 1 and sticks fast to it, preventing a leak from occurring. And, since an outer circumference of a plastic band 26 is formed into a drum type, even if a piston 2 is tilted so some extent as it receives lateral force, such a case that an end face of the piston 2 bits into the cylinder 1 and causes a stick penomenon is in no case produced there, thus sliding motion in the piston 2 becomes smoothed, and a feeling of comfortable car driving is yet more improved.
