SELF-OILING PNEUMATIC TOOL

摘要

A self-oiling pneumatic tool includes a pneumatic tool assembly, in which a driver unit is mounted. The pneumatic tool assembly has an end forming an air connection terminal. An oiling unit is arranged between the driver unit and the air connection terminal and located in the pneumatic tool assembly and includes an outer tube hermetically enclosing an inner tube so that an oil preservation space is formed therebetween. The inner tube has a circumferential wall in which a second oil supply aperture is formed and in communication with a passage of the inner tube that is in communication with the driver unit. When external air is supplied through the inner tube to the driver unit, oil stored in the oil preservation space is allowed to flow through the second oil supply aperture into the passage of the inner tube to then flow to the driver unit to achieve self-oiling.

主权项

1. A self-oiling pneumatic tool, comprising a pneumatic tool assembly, the pneumatic tool assembly comprising a driver unit arranged therein, the pneumatic tool assembly having an end forming an air connection terminal, characterized in that:
an oiling unit is arranged between the driver unit and the air connection terminal and the oiling unit comprises an outer tube and an inner tube, the outer tube hermetically enclosing outside the inner tube in such a way that an oil preservation space is formed between the outer tube and the inner tube, the inner tube comprising a passage formed therein, the passage being in communication with the driver unit, the inner tube having a circumferential wall in which at least one second oil supply aperture is formed, the second oil supply aperture being in communication with the passage.
