COMPOUND VALVE
First Claim
1. A compound valve, comprising:
- a valve element being cylindrical-shaped and rotationally movable about a spindle thereof, for opening/closing flow paths of fluid media, wherein;
the valve element includes a partition member being planar, having a major axis in a direction along a cylindrical axis of the valve element, and separating, along a direction of the major axis, an internal space of the cylindrical shape into spaces whose cross-sectional shapes perpendicular to the cylindrical axis are semicircular; and
a plurality of opening portions each formed in an outer circumferential side surface of the valve element, for allowing inflow or outflow of fluid media, wherein the valve element is capable of controlling quantities of flows of fluid media flowing in the flow paths by altering a rotation angle about the spindle.

Abstract
A compound valve includes a body having a valve chamber; a cylindrical-shaped valve element having opening portions in its lateral side surface for allowing heat media to flow inside of the valve element, and a partition member there inside in the longitudinal direction; and a motor for controlling a rotation angle of the valve element, and the opening portions communicate with either one of a first heat-medium inflow port or a second heat-medium inflow port, and with either one of a third heat-medium outflow port or a fourth heat-medium outflow port; two heat media having different properties flow adjacent to the partition member; and, by controlling, by a rotation angle of the motor, areas of the communicating inflow ports and the opening portions, and those of the communicating outflow ports and the opening portions, the quantities of flow are controlled.
