PURPOSE:To drive an oil pump simply and inexpensively by leading internal pressure in a crankcase into the oil pump,, and constituting the oil pump to be drivable in a way of utilizing variations in the internal pressure via a pressure responder and an intermittent feed mechanism or the like. CONSTITUTION:Internal pressure in a crankcase in an engine is led into an oil pump 4 via an inflow hose 6. And a diaphragm 28 is pulsated by the internal pressure and a connecting rod 26 is reciprocated, while linkage 27 is made into reciprocating angular motion and an intermittent feed mechanism 23 is made into intermittent rotational motion. In addition, a ratchet wheel 17 is made into the intermittent rotational motion in one direction, while a lift cam 17a is moved up and down. With this constitution, a plunger sleeve 14 is moved in rotation while it is moved up and down, making it perform a pumping action, and oil in an oil tank fed out of a feed hose 3a is fed to every part of the engine via an outflow hose 7. |
