Abstract
Hydraulic fluid leakage collection apparatus that includes an annular collection chamber that is carried in a cylindrical member within which a piston member is movable. A seal and wiper are carried by the clamp cylinder of an injection molding machine to seal the space between the clamp piston and the clamp cylinder and also to wipe from the surface of the clamp piston accumulated hydraulic fluid. Positioned adjacent the wiper ring is a drain passageway that is adapted to receive the hydraulic leakage fluid that is wiped by the wiper ring from the piston. A conduit extends from the drain passageway to an air operated vacuum pump to draw the leakage hydraulic fluid from the drain passageway. A container is positioned in the conduit between the drain passageway and the vacuum pump to collect the hydraulic leakage fluid that is collected.
