A ball dump valve for a rotary clutch assembly has a valve housing with a shoulder which abuts a wall surface on the housing of the clutch assembly. A displaceable component or finger is swaged to abut another wall on the clutch assembly housing to thereby securely fasten the valve housing in the clutch assembly. The interior of the valve housing has a chamber in which is disposed a ball. The chamber has a frusto-conical surface with an opening therein. The ball is seated by pressure against the frusto-conical surface to close the valve and is urged along the frusto-conical surface by centrifugal force to open the valve.
A vent valve for a thermostatic valve of a coolant circuit of an internal combustion engine has a ball with a radius and a diameter and serving as a sealing element, and a one-piece metal cage for the ball. The cage has a pot-shaped part with an inside diameter larger than the diameter of the ball, and a bottom having a valve opening surrounded by an outwardly projecting neck. The cage is shaped in one piece from an originally flat metal sheet by stamping, deep-drawing, and pressing, and the pot-shaped part has a height approximately the radius of the ball, and an edge abutted by a plurality of uniformly distributed tabs located on an axial extension of the pot-shaped part, the tabs having inwardly bent ends to retain the ball in the cage with play, the length of the tabs being greater than or equal to the height of the pot-shaped part.
A check valve assembly is adapted to be installed in a pre-combustion chamber for an internal combustion engine. The check valve includes a ball closure element which is responsive to normal fuel/air supply pressure to be held in an open position and is responsive to expansion pressure in the chamber to close the supply line and to prevent back flash of ignited fuel into the supply line.
A check valve having an elongated body with bore therethrough, the bore having a small diameter section abutting a downstream frustoconical section with an increasing diameter, a ball positioned downstream of the small diameter section and movable in the frustoconical section and a pin blocking the bore to keep the ball at or near the frustoconical section and near to the small section, such that a reversal in fluid flow will seat the ball within the frustoconical section and block the bore.
