摘要： A refrigerant control valve apparatus which maintains improved sealing ability while being restrained from being enlarged includes a housing including a first discharge port and a second discharge port which includes a smaller diameter than the first discharge port, a rotor rotatably housed at the housing, a bore portion provided at an outer wall portion of the rotor to control a flow of refrigerant relative to the first discharge port and the second discharge port, a second seal portion of the second discharge port being configured to make contact with an edge portion of the bore portion in a case where the rotor is specified at any rotation position for sending out the refrigerant to the second discharge port.

摘要： An opening and closing valve includes: a housing that has an internal space formed to have a posture along an axis and has inflow and outflow ports communicating with each other via the internal space; a valve body that is switchable between a closed position where flow of a fluid between the inflow and outflow ports is blocked and an open position where the flow of the fluid between the inflow and outflow ports is allowed, by being operated in the internal space along the axis; a direct current motor that operates the valve body in a direction along the axis; and a damper unit that decreases a moving speed of the valve body immediately before the valve body reaches at least one of the open and closed positions by a drive force of the direct current motor.

摘要： A refrigerant control valve device includes: a spherical rotor having an opening and rotating about a rotation axis; a housing including at least one circumferential port, and an axial port, the housing allowing a refrigerant to flow therein and the rotor being accommodated in the housing; at least one hole formed in the rotor and allowing the internal space of the rotor and the circumferential port to communicate with each other when the rotor rotates; a ring-shaped seal member installed coaxially with the circumferential port; a biasing member applying a biasing force to the seal member; a packing body provided between the housing and an outer diameter portion of the seal member; and a fixing member holding the packing body with the housing in a direction in which the circumferential port extends.
