DAMPING VALVE AND SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2017/047499
Kind Code:
A1
Abstract:
Damping valve V comprises: a valve member 6 that opens and closes the upstream side and the downstream side of a pilot channel 18 by way of a pressure control valve 6b detachably seated in a pressure control valve seat 5f and an open-close valve 6c detachably seated in an open-close valve seat 50b; a disc spring 60 that is interposed between a step 5g and the valve member 6 and biases the valve member 6 in a direction to separate the pressure control valve 6b from the pressure control valve seat 5f and to bring the open-close valve 6c closer to the open-close valve seat 50b; and a solenoid S that can drive the valve member 6 against the biasing force of the disc spring 60. When the disc spring 60 is in a natural length state, a gap is formed between the open-close valve 6c and the open-close valve seat 50b.
