Title:
Pressure actuated valve and refrigeration cycle
Document Type and Number:
Japanese Patent JP6367164
Kind Code:
B2
Abstract:
The invention provides a pressure operating valve and a frozen cycle, capable of suppressing the vibration of a valve member (2), thereby preventing a needle-like portion (21) from repeatedly colliding with the valve port (13) or preventing the occurrence of an abnormal sound. A diaphragm (43) is operated by the pressure of the fluid of a primary side joint (11a), and a valve port (13) is opened and closed by the needle portion (21) of the valve member (2). At least a part of a projection portion (24) serving as the valve member (2) is disposed on the downstream side of the valve port (13). A force applying mechanism is provided for applying force of the fluid on the valve member (2) toward one side of an axis L. The force applying mechanism is a projection portion (24) having a D-shaped cross section (241) of the valve member (2). The flow rate of the refrigerant is increased on the D-shaped cross section (241) side of the valve member (2).
