減圧弁
Document Type and Number:
Japanese Patent JP7243284
Kind Code:
B2
Abstract:
A pressure reducing valve includes a piston (42; 105) disposed in a cylinder chamber; a valve element (21; 127) that is coupled to the piston (42; 105) and opens and closes a valve seat (22; 102); a valve spring that biases the valve element (21; 127) in a direction in which the valve element (21; 127) is moved away from the valve seat (22; 102); and a biasing member that biases the valve seat (22; 102) toward a side opposite to the piston (42; 105). The pressure reducing valve is configured to reduce a primary pressure of a fluid to a secondary pressure. The valve seat (22; 102) is disposed such that the valve seat (22; 102) reciprocates in the same direction as a direction in which the valve element (21; 127) reciprocates in the primary pressure chamber. As a difference between the primary pressure and the secondary pressure increases, the valve seat (22; 102) moves toward the secondary pressure chamber.
