| 20090146415 | Pipe-joint structure for heat exchanger - A pipe-joint structure according to the present invention is advantageously used in an air-conditioner system mounted on an automotive vehicle. A compressor including an expansion valve is connected to an evaporator through the pipe-joint structure. The pipe-joint structure includes an inserting portion of a pipe connected to the compressor and a socket connected to the evaporator. The inserting portion is inserted into a hole formed in the socket. A front end of the inserting portion is positioned not to extend into an enlarged portion of the socket to thereby avoid formation of a dead-end small space between the inserting portion of the pipe and the enlarged portion of the socket. Refrigerant entering the socket from the evaporator smoothly flows without stagnation, and thereby noises caused by the refrigerant flow are suppressed. | 06-11-2009 |

First and second releasable locking means secure the collar to the auxiliary device. The locking means are arranged such that when both are locked relative movement between the connector and the auxiliary device is prevented. However, when the first locking means is released and the second locking means is locked, relative rotation between the connector and the auxiliary device about the central axis is permitted, and a predetermined amount of relative movement along the axis is also permitted. In this way, the connector can be fitted in a variety of orientations relative to the auxiliary device and angular relative adjustment is possible while the two remain connected and sealed. | 02-06-2014 |
