OIL WITHDRAWING APPARATUS

摘要

There is provided an apparatus for withdrawing a liquid from a container, specifically oil from the crankcase of an engine. A rigid, fluid-tight receptacle has a circular top wall and an upstanding rim at the periphery thereof. From the receptacle a vacuum line extends, for connection to a source of vacuum, and the vacuum line has a check valve for preventing backflow of gas. An elongated flexible probe is provided for insertion into the container to take up the liquid, and a conduit extends from the receptacle to the probe, which conduit is divided into two portions. The first portion extends from the receptacle to a control valve, while the second section has its one end connected to the probe and has its other end adapted for selective attachment to and detachment from the control valve. The second portion of the suction conduit has an inside diameter large enough to receive the flexible probe, and has a length substantially equal to the inner circumference of the rim. In this manner, the probe can be inserted fully into said other end of the second portion of the suction conduit, and then the latter can be lodged in circular configuration inside and against the rim for purposes of storage and transport. The probe, which is a sensitive and delicate part of the apparatus, is thus doubly protected. Firstly it is protected by being within the conduit itself, and secondly it is lodged permanently within a rigid rim of the receptacle, along with the conduit itself, thereby preventing accidental knocks, pinching, etc.
