  • Patent number: 8273195
    Abstract: A heat treatment method of heat-treating a steel tube provides the steel tube with satisfactory workability and high pressure resistance capable of coping with a recent increasing trend of pressure dealt with by a recent common rail type fuel injection system. A steel tube of a desired size is formed by drawing a material of a steel containing at least vanadium. The steel tube is processed for normalizing by holding the steel tube at high temperatures between 950 and 1000° C. for a predetermined time and slowly cooling the steel tube at a predetermined cooling rate. Then, the steel tube is processed for tempering by heating the steel tube at a temperature between 500 and 700° C. and cooling the steel tube to an ordinary temperature at an optional cooling rate.

  • Patent number: 7566077
    Abstract: A quick-connect coupling has a retainer for retaining a tube in a coupling body. The retainer is pressed in the coupling body so as to lock the tube in place in the coupling body. The retainer cannot be fully pressed in the coupling body and projects from the coupling body to indicate that the tube is not properly connected to the coupling body unless the tube is inserted completely in the coupling body. The retainer is combined with complete connection verifying legs that enables the retainer to be able to be pressed in the coupling body when an annular ridge formed in an end part of a tube inserted in the coupling body is advanced beyond a position where the retainer is able to engage with the annular ridge.

  • Patent number: 7390029
    Abstract: A quick connector has a housing, a retainer for locking a tube at a correct position for complete connection in the housing and a restraining ring for restraining the retainer from being pressed into the housing to its locking position unless the tube is inserted in the housing and placed at the correct position for complete connection to avoid connecting the tube to the quick connector in a falsely locked state. The restraining ring is provided with locking bars that engage with the legs of the retainer to restrain the retainer from being pressed into the housing. The locking bars permit releasing the restraining ring to its releasing position to enable the retainer to be pressed into the housing to the locking position.
