Title:
Expansion valve
Document Type and Number:
Japanese Patent JP6011498
Kind Code:
B2
Abstract:
When a power element expands in a direction of a uniaxial center, a diaphragm is pressed, in the direction of the uniaxial center, against a pressing portion of a lid member fixed to a body unit. A holder member of the power element is displaced away from the pressing portion as the diaphragm further expands outward in the direction of the uniaxial center. Displacement of the holder member in the direction of the uniaxial center is transmitted to a spherical valve, thereby increasing or decreasing an opening degree of the spherical valve. Accordingly, it is not necessary to dispose a member which may cause complicated processing work for an expansion valve between the holder member and the spherical valve, e.g., a member which needs complicated welding processing work.
