20090045624 | BITE TYPE TUBE CONNECTION STRUCTURE, TUBE FITTING, VALVE, CLOSING VALVE, REFRIGERATING CYCLE DEVICE, HOT-WATER SUPPLY DEVICE, BITE TYPE TUBE CONNECTION METHOD, AND ON-SITE TUBE CONNECTION METHOD - A fitting has a bite type tube connection structure with a bite type sleeve in cylindrical form. The bite type sleeve is formed of a primary deforming portion and a secondary deforming portion. The primary deforming portion bites into a connection tube | 02-19-2009 |
20090102191 | Flareless Pipe Coupling Structure, Flareless Pipe Coupling Method, And On-Site Pipe Coupling Method - A guide tapered surface | 04-23-2009 |
20090267343 | PIPE JOINT, REFRIGERATION DEVICE, AND HEAT PUMP-TYPE HOT WATER DEVICE - A pipe joint includes a joint body | 10-29-2009 |
20090309357 | BITE-IN TYPE PIPE JOINT, REFRIGERATING APPARATUS, AND WATER HEATING DEVICE - A bite-in type pipe joint includes a first joint member having an internal thread and a second joint member having an external thread. An annular ferrule is formed integrally with the second joint member. By the time the first and second joint members are fastened to each other, the ferrule separates from the second joint member and bites into a pipe. The second joint member has a cylindrical cover that covers the ferrule. This structure prevents a distal portion and a tapered surface of the ferrule from being damaged when the joint member is handled. A refrigerating apparatus and/or a water heating device can include one or more of the pipe joints. | 12-17-2009 |
20110108753 | BITE TYPE PIPE CONNECTION STRUCTURE, VALVE, BITE TYPE PIPE JOINT, AND FREEZING DEVICE - A bite type pipe connection structure is used to connect a large diameter pipe that is previously set as a standard specification. The bite type pipe connection structure includes a spacer | 05-12-2011 |
20110214450 | BITE-IN TYPE PIPE CONNECTION STRUCTURE, VALVE, BITE-IN TYPE PIPE JOINT, AND REFRIGERATION DEVICE - A bite-in type pipe connection structure is provided, the pipe connection structure being capable of, even if piping connection work is performed with a length of piping inserted insufficiently, minimizing deterioration of air-tightness at the joint portion, at which the piping is connected, due to an offset load acting on the piping. Also provided are a valve, a bite-in type pipe joint, and a refrigeration device using the bite-in type pipe connection structure. A ferrule | 09-08-2011 |
20130175351 | EXPANSION VALVE - An expansion valve for a refrigerant circuit of a refrigeration apparatus is configured to depressurize a liquid refrigerant. The expansion valve includes a valve main body with a valve seat opening into a valve chest formed in the valve main body and a valve body movable relative to the valve chest in a reciprocating manner. An orifice is formed in the valve seat. The orifice has an orifice entrance with a smallest diameter, an orifice middle section widening in diameter along a direction of refrigerant outflow from the orifice entrance so as to form a first taper angle, and an orifice exit either widening in diameter or not in diameter along the direction of refrigerant outflow from the orifice middle section so as to form a second taper angle smaller than the first taper angle. | 07-11-2013 |
20140232111 | FLARELESS TUBE CONNECTION STRUCTRUE - A flareless tube connection structure includes a joint body, a coupling member threadedly mounted to the joint body, and front and back ferrules thrilled separately from the joint body and the coupling member and clamped between the joint body and the coupling member. The front and back ferrules are formed separately from each other and can be provisionally assembled together before the coupling member is mounted to the joint body. | 08-21-2014 |
20140353969 | TUBE CONNECTION STRUCTURE - A tube connection structure includes a joint body and a coupling member. The coupling member has a fastening part threaded with the joint body and a tool-engaging part gripable with a fastening tool. The coupling member and the joint body are-configured such that the tool-engaging part is separated from the fastening part after the coupling member is mounted to the joint body. The joint body and the coupling member have a threading contact part. The components of the threaded contact part are in contact with each other so that the threading of the coupling member over the joint body is limited before the tool-engaging part is separated from the fastening part. | 12-04-2014 |
