Title:
INTEGRATION VALVE FOR HEAT PUMP
Document Type and Number:
Japanese Patent JP2015017763
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an integration valve for a heat pump capable of solving problems in accompany with a refrigerant charging operation, and improving mountability to a loaded object, in a heat pump cycle capable of being switched to a gas injection cycle.SOLUTION: Components such as an opening/closing mechanism 16, gas-liquid separating means (gas-liquid separating space 141b), a fixed throttle 17, and a solenoid valve 18 necessary for making a heat pump cycle 10 function as a gas injection cycle, is integrally constituted as an integration valve 14. Further a bypass valve element 183 for opening and closing a bypass communication passage 144 for communicating an upstream-side passage 142h and a downstream-side passage 142g of a gas-phase refrigerant passage 142b is additionally disposed on the integration valve 14. The bypass valve element 183 is constituted to open the bypass communication passage 144 when a gas phase-side valve element 181 is displaced to a closing position of a liquid-phase refrigerant passage 141d.
