Synthetic resin ferrule for lubricating pump

摘要

The ferrule (20) is constituted by two parts. One part (22) is a direction retaining element which has a fitting hole and a projecting gripping part. The other part, the ferrule main body (21) has a wall (26) which fits in the fitting hole. A fitting claw (8) enables the main body to fit in the suction orifice (5) in the pump body. Several notches (9) are formed in the ferrule main body and a retaining flange (25) retains the direction holding element clamped between the pump body and the ferrule main body. Two elements (19) retaining the ferrule projecting part are formed on the pump body.
