Title:
RECIPROCATION STROKE ADJUSTER
Document Type and Number:
Japanese Patent JPS5618082
Kind Code:
A
Abstract:
The adjustment screw that regulates the stroke length of the piston that drives a diaphragm pump is rotated by means of a clutch and "diamond-back" screw structure. By selectively engaging either of two oppositely oriented one-way clutches, one of two respective associated nuts that ordinarily rotate freely on the "diamond-back" screw is blocked from rotation when the screw moves longitudinally in one direction. Thus locked, the nut compels the "diamond-back" screw to rotate, thereby turning the adjustment screw with which it is connected in order to produce the desired increase in piston stroke length.
