ABSTRACT:
A combination fluid level indicator and fluid discharge device is provided for preventing inaccurate fluid level indications and facilitating fluid discharge from a compressor or other container. The device includes a body or conduit having an inlet end installed in an aperture through to a compressor housing to fluidly communicate with the compressor and receive the lubricating oil therefrom. A visual indicator provides an indication of the level of the oil within the compressor housing. A discharge port with cap, plug, valve or other flow control member permits selective discharge of the fluid from the compressor through the body. The device is installed in an aperture extending through a side of a compressor housing proximate the bottom thereof and indicates the level of lubricating oil within the housing and permits discharge of oil from the housing.
