Control apparatus for lubrication pump

A control apparatus for a lubrication pump to supply lubrication oil to a plurality of working machines comprising

• a tank (10) for storing lubrication oil;
• a cover (11) being covered on said tank (10) having a control panel (12), an oil inlet (13), and a motor (14) formed thereon;
• a pump (20) in said tank (10) being connected to said motor (14);
• a first oil passage (21) being horizontally formed at an upper portion of said pump (20) having two outlets (21A, 21B) at two distal ends thereof each of which is connected to an external pipe which further provides oil to a plurality of working machines connected thereto;
• a second oil passage (23) being formed in said pump (20) and in communication between said first oil passage (21) and a lower inner space of said tank (10);
• a third oil passage (25) being obliquely formed at the upper portion of said pump (20) and in communication with said first oil passage (21) at an top end thereof;
• a fourth oil passage (15) horizontally formed in said cover (11) having a left end thereof in communication with said third oil passage (25) and a right end;
• a pressure-adjusted valve 31 being rotatably engaged inside said fourth oil passage (15) from the left end thereof having an L-shaped hole (32) therein for in communication with said fourth oil passage (15);
• a hole (16) being formed at an lower surface of said cover (11) and in communication with said L-shaped hole (32);
• a control circuit comprising a control/setting unit (40) which is electrically connected to a power driving unit (50) which is connected to said motor (14) for driving the latter, said control/setting unit (40) comprising a microprocessor (41) and a displaying/setting means (43) for setting an intermittent time interval to intermittently actuate said power driving unit (50), which in turn actuates said motor (14) to rotate intermittently, thus providing oil to said working machines intermittently.
