Title:
ATTENUATION FORCE VARIABLE VALVE
Document Type and Number:
Japanese Patent JP2019027521
Kind Code:
A
Abstract:
To obtain an attenuation force variable valve which is short in entire length while securing a necessary motion stroke.SOLUTION: An attenuation force variable valve comprises a case C for accommodating a working fluid, and first and second housings H1, H2 for partitioning the inside of the case C into first and second fluid chambers 1, 2. A control mechanism 5 for adjusting a flow rate of the working fluid over the first and second fluid chambers 1, 2 is arranged in the first housing H1. The control mechanism 5 comprises a first pilot chamber PR1 communicating with the first fluid chamber 1, a second pilot chamber PR2 communicating with the second fluid chamber 2, and a valve body V which is changed in posture while partitioning the first and second pilot chambers PR1, PR2. An adjusting mechanism 3 for setting flow rates of the fluids in the first and second pilot chambers by adjusting a change of the posture of the valve body V, and an actuator 4 are arranged in the second housing H2, and a check valve V3 for making the working fluid flow out to the first fluid chamber 1 from the first pilot chamber PR1 at a boost of the inner pressure of the first pilot chamber PR1 is arranged at a boundary position between the first and second housings H1, H2.SELECTED DRAWING: Figure 1
