20130292591 | QUICK-RELEASE COUPLING - A quick-release coupling includes a socket defining a first passage in a connection port thereof, a locking member mounted in a front end of the socket and adapted for locking an inserted external male mating connector, an air valve control device mounted in a rear end of the socket, and a leak-proof device having a stopper mounted in the front end of the socket and defining therein a second passage, which is kept in communication with the first passage upon insertion of an external mating male connector into the front end of the socket to move the stopper backward, or blocked from the first passage after removable of the inserted external mating male connector and a forward movement of the stopper by the air valve control device. | 11-07-2013 |
20130291976 | QUICK-RELEASE COUPLING - A quick-release coupling includes a socket defining a first passage in a connection port thereof, a locking member mounted in a front end of the socket and adapted for locking an inserted external male mating connector, an air valve control device mounted in a rear end of the socket, and a leak-proof device, which includes a stopper mounted in the front end of the socket and defining an axially extending second passage and a transversely extending third passage and a plurality of gasket rings mounted around the stopper at two opposite lateral sides of the third passage for allowing fluid communication between the first passage and the second and third passages or blocking the first passage from the second and third passage after movement of the stopper relative to the socket between two positions. | 11-07-2013 |
20130061713 | CAM WHEEL ASSEMBLY FOR REFRIGERANT RECOVERY MACHINE - A high-durability cam wheel assembly mounted in a shell of a refrigerant recovery machine is disclosed to include a frame member ( | 03-14-2013 |
20110132018 | ELECTRONIC INSTRUMENT FOR REFRIGERANT RECOVERY MACHINE - Used in a refrigerant recovery machine having a refrigerant input pipe and a refrigerant output pipe, an electronic instrument is disclosed to include a control unit, a LCD device controllable by the control unit to display the operation status of the refrigerant recovery machine, and a pressure sensor unit having an input pipe pressure sensor and an output pipe pressure sensor for detecting the pressure in the input pipe and the pressure in the output pipe and transmitting the respective detected pressure values to the control unit for comparison with a pre-set pressure threshold limit value so that the control unit controls the operation of the refrigerant recovery machine subject to the comparison results. | 06-09-2011 |
20110079036 | REFRIGERANT RECOVERY MACHINE WITH IMPROVED CAM WHEEL ASSEMBLY - A high-durability cam wheel assembly mounted in a shell of a refrigerant recovery machine is disclosed to include an open frame member, rigid wear strips mounted in the open frame member at two sides, a sliding block having friction cylinders arranged in parallel at two opposite sides and respectively disposed in contact with the rigid wear strips and a cam wheel set formed of a first cam wheel and a second cam wheel and inserted through an axle bearing in sliding block for causing the sliding block to move back and forth in the open frame member. | 04-07-2011 |
