Title:
ELECTRICALLY OPERATED VALVE
Document Type and Number:
WIPO Patent Application WO/2024/080127
Kind Code:
A1
Abstract:
Provided is an electrically operated valve 11 comprising: a valve body 13 having a valve chamber 14; a valve member 31 that has a flow path space 32 inside, and is rotationally driven in the valve chamber to switch a flow path of fluid; and a transmission mechanism including a drive shaft 41 that transmits a driving force for rotating the valve member to the valve member. The valve body includes: a first flow path hole 15 that communicates with the flow path space to allow the fluid to flow into the flow path space; a second flow path hole 16 of which the state of communication with the flow path space is changed depending on the position of rotational displacement of the valve member, and which communicates with the flow path space at a first rotational displacement position of the valve member to allow the fluid to flow out from the flow path space; and a third flow path hole 17 of which the state of communication with the flow path space is changed depending on the position of rotational displacement of the valve member, and which communicates with the flow path space at a second rotational displacement position of the valve member to allow the fluid to flow out from the flow path space. A rotation axis X of the valve member and a rotation axis Y of the drive shaft intersect with each other.
