Abstract
The reservoir cap for a hydraulic fluid reservoir includes a cap plate and an integral stick, a gasket, a cup and a spring. The gasket is telescopically received on the stick and contacts a cap gasket surface on the cap plate. The cup has two radially extending ears with ramp contact surfaces and a central bore. The central bore has two spaced apart flat cup bore surfaces and cup projections that extend radially into the central bore. A coiled compression spring has one end in contact with the cup and another end in a spring retainer groove on the stick. The cup is mounted in a preliminary position on shelves on the stick. Rotation of the stick relative to the cup moves the cup off the shelves and the spring moves the cup to a working position.
