Title:
HYDRAULIC PUMP
Document Type and Number:
Japanese Patent JP3692205
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To make the spring load of a suspension spring, kept installed in a hydraulic shock absorber intact, alterable by means of hydraulic control as maintaining a good appearance and operability.
SOLUTION: This hydraulic pump is composed of having a screw-shaped rod 13 being retractable to or from a pump cylinder 11, and a piston 14 being slidably stored in an oil chamber as keeping in touch with a tip of this rod 13 and partitioning off the oil chamber 15 within the other end side of this pump cylinder 11, and it is made up of having an operating handle 16 being formed into a headed tubular shape held so as to make it rotatable at a home position in an inner circumference of one end of the pump cylinder 11 as storing a base side of the rod 13 inside, while a base part 13c of the rod 13 is linked up with an inner circumference of the operating handle 16 and thereby a rotation to be synchronized with the handle 16 of the rod 13 is made possible to be done, therefore the oil chamber 15 is interconnected to a hydraulic shock absorber at the outside via a through hole 11a bored on the bottom of the pump cylinder 11, while this oil chamber 15 is narrowed by a slide motion of the piston 14 due to a rotation of the rod 13.
