Document Type and Number:
Japanese Patent JP6302717
Kind Code:
B2
Abstract:
The invention provides an electrically operated valve which can reduce an abnormal noise generated in the case that a fluid is flows in a first flowing direction and a second flowing direction, while suppressing a flow rate loss of a fluid with a simple structure. An electrically operated valve is provided with a valve main body (5) in which a valve chamber (7) is defined in an inner portion and a first opening (11a) and a second opening (12a) are formed in a side portion and a bottom portion, a valve seat member (8) which has an valve port (9) open to the valve chamber (7) and a valve seat (8a) and is provided in the second opening (12a) of the valve main body (5), a valve body (20) which is arranged in the valve chamber (7) so as to be movable up and down, and an elevation drive portion (50) which moves up and down the valve body (20) in relation to the valve seat (8a), and a porous body (4) constructed by a foam metal is arranged along a portion which is positioned in a side portion of the valve port on the inner wall surface of the valve main body (5).
