Abstract

A refrigerant valve device may include a base provided with an inlet port, an outlet port and a valve seat face; a cover to section a valve chamber between the valve seat face and the cover; a valve body turnably disposed at a position shifted to a side of one port inside the valve chamber, the valve body being provided with a contact face sliding on the valve seat face; and a valve body drive mechanism to turn the valve body. The valve body drive mechanism may turn the valve body and thereby a refrigerant flowing passage from the inlet port to the outlet port through the valve chamber is switched at least to a first refrigerant flowing passage and to a second refrigerant flowing passage. The refrigerant flowing amount in the first refrigerant flowing passage may be smaller than a refrigerant flowing amount in the second refrigerant flowing passage.
