Abstract
An oil airless sucking machine that has features of easy control, smaller volume for carrying, and is suited to any size oil container. The machine has a three-way T-shaped nozzle carrier, which has a radial valve through-hole built as a valve buckle for a control valve cock fitting so as to construct a control valve. A non-home switch handle snaps on long tenons of the valve cock for spinning together, and by means of a friction force between a couple of O-rings located approaching both ends of the valve cock and the valve buckle, the non-home switch can be kept in any position for cut-in or off processes without needing to be held all the time during running. The dividable joint structure of the cap and the nozzle carrier makes changing different size oil tanks for working on different gear boxes easy.
