Abstract
An improved peristaltic pump which provides for rotating the head an offset angle relative to the rotor center and which includes a pivoted housing structure that can be adjusted by a spring loaded set screw so as to vary the quantity of material pump. By adjusting the set screw, the spacing between the head and the rotor can be adjusted to vary the volume of the pump. A one-way clutch assures that fluid cannot be supplied in a reversed direction through the pump.
