Abstract

An improved inlet duct for a cartridge type control valve which includes, a cup-like member having a bottom wall and a side wall defining the fluid transfer chamber in said control valve, is formed from a tubular member having a J-shaped configuration inverted in assembled position in the control valve, the tubular member has an inlet leg and an outlet leg continuous with the inlet leg, the inlet leg is staked in fluid tight engagement in the bottom wall of the cup-like member a predetermined distance from the side wall and defines an inlet port in the staked position extending to the exterior of the cup-like member, and an adhesive is applied between the bottom wall of the cup-like member and the exterior of the inlet leg to insure maintaining the said fluid tight seal, the outlet leg has an outlet port and in assembled position is so cantilevered into the fluid transfer chamber that the outlet port faces the bottom wall in the center line of the control valve, and an inwardly directed indentation in the side wall engages the inlet leg of the tubular member to reenforce the inlet duct in assembled position, and to thereby prevent misalignment of the outlet port during operation and installation of the control valve.
