Embodiment Construction

[0018] Embodiments of the present invention will be described below with reference to the drawings. The same reference numerals are used throughout the several figures to designate the same or corresponding parts.

[0019] Such as figure 1 The valve of one embodiment of the present invention is a damper valve V embodied in the piston portion of the damper D as shown. The shock absorber D is interposed between the vehicle body and the axle of a vehicle such as an automobile. In the following description, for the convenience of description, unless otherwise specified, the figure 1 The up and down of the buffer D shown are simply referred to as "upper" and "lower".

[0020] In addition, the installation object of the shock absorber provided with the valve which concerns on embodiment of this invention is not limited to a vehicle, It can change suitably. In addition, the direction of the bumper in the attached state can be changed as appropriate according to the object to be a...

Abstract

A valve (V) is provide with: a valve case (5); and an annular valve body (8) of which one of inner and outer circumferential ends is set as a free end (8c) so as to be movable to both sides in the axial direction relative to the valve case (5), wherein the valve case (5) has an annular opposite surface (5e) that can face the free end (8c) with a gap (P) therebetween, and a guide surface (5h) thatis positioned on one side in the axial direction of the opposite surface (5e) and connected to a part in the circumferential direction of the opposite surface (5d), and the guide surface (5h) inclinesin such a direction as to become more distant from the valve body (8) with increase in the distance from the opposite surface (5e).

Description

technical field [0001] The present invention relates to a valve and a shock absorber equipped with the valve. Background technique [0002] Conventionally, valves have been used, for example, to apply resistance to the flow of liquid that occurs when a shock absorber expands and contracts, thereby generating a damping force. In addition, such a valve has a structure in which one of the inner circumference and the outer circumference is used as a fixed end fixed to the valve housing, and the other is used as a free end movable to both sides in the axial direction. Shaped valve core, a gap that allows liquid to pass is formed on the outer or inner circumference of the free end of the valve core (refer to JP2009-299768A). [0003] According to the above structure, when the expansion and contraction speed (piston speed) of the shock absorber is in the low speed range to the extent that the valve body does not bend, the gap formed on the outer or inner circumference of the free ...
