A demand responsive flow control valve including a housing in a fluid conduit between a pump and a motor vehicle power steering gear, a flow control orifice in the fluid conduit, and a valve pintle supported on the housing for linear translation. An inboard stop on the housing engageable by the valve pintle defines an active position of the valve pintle, obstructing the flow control orifice and reducing the effective area of the latter. The inboard stop is a tubular sleeve interference fitted in a bore in the housing. The position of the tubular sleeve on the housing corresponding to the active position of the valve pintle is established by inducing linear translation of the tubular sleeve into the bore in the housing as a unit with the valve pintle while monitoring the corresponding flow rate through the fluid conduit. When the actual flow rate attains a magnitude equal to a desired or scheduled low flow of the flow control valve, the corresponding calibrated position of the tubular sleeve is rigidly captured by friction attributable to the interference fit between the tubular sleeve and the housing.

Demand responsive flow control valve

A roller chain conveyor having wire cross flights and attachments for releasably mounting said cross flights on the chain to provide a conveying surface. The attachment has at least one groove therein to receive an extended portion of the cross flight. The attachments may also be used in conveyors having multiple roller chains therein.
