Claims

[Scope of utility model registration request]

A passage that leads engine cooling water as a heat medium to the heater core.
A heating medium passage switching valve for a vehicle regenerative heating system that selectively switches between a main passage leading directly to a heat storage passage and a passage passing through a heat storage unit leading engine exhaust heat through a heat storage unit, which has a symmetrical shape with respect to the valve axis. It is equipped with a butterfly valve and a valve housing forming a valve chamber having a shape that envelops the rotation locus of the butterfly valve. In addition to the butterfly valve, which forms a cooling water inlet from the engine and a cooling water outlet to the heater core that face and are substantially opposite to each other, and faces the other space at the - position and shuts off the cooling water inlet and outlet. A water supply port to the heat storage device faces the space on the cooling water inlet side partitioned by the valve at a position, and a water supply port from the heat storage device faces the other space at the - position and faces the space on the cooling water outlet side at the other position. A heat transfer medium passage switching valve formed with a return port and a return port.
