摘要： 1,1,1,2-Tetrafluoroethane is used in a refrigerator as the refrigerant, while a polyolester oil which is well compatible with the refrigerant is used as the base oil and a phenolic antioxidant, a specified amine and a phosphoric triester are added thereto to give a refrigerator oil composition. Thus the hydrolysis of the polyolester oil can be prevented to thereby protect the sliding members such as a roller and a vane from the corrosion and wear which are caused by the hydrolysis.

摘要： A vehicle fuel tank assembly is provided with a fuel tank and a fuel pump unit. The fuel tank is mounted on a saddle-riding type vehicle. The fuel tank has a flat shape elongated in the front-to-rear direction. The fuel pump unit includes a main body, a support body extending from the upper part of the main body in the longitudinal direction of the fuel tank, and a fuel level gauge supported and extending on the support body. The fuel level gauge includes a fuel level gauge body, a float arm pivotally supported by the gauge body, and a float on the free end of the float arm. The float arm extends in the longitudinal direction of the fuel tank and takes a highest swing position in an intermediate level of the height of the fuel tank. The fuel tank assembly enables fuel level detection in a wide range.

摘要： While enlargement of cover members attached to an engine body is avoided, the flexibility of the shapes of the cover members is increased and it is made possible to lead to a predetermined position drainage discharged from a cooling water pump attached to the external surface of a lateral wall of the engine body. A drainage discharge hole for discharging drainage is provided in a lower portion of a pump case. An engine side rib leads downward drainage discharged from the drainage discharge hole is integrally provided on an engine body forming part of the engine body so as to project from an external surface of a lateral surface thereof.
