Abstract:
A lubricating system for an engine, comprising:an oil pump having an inlet port and an outlet port, said oil pump having a rotor supported for rotation about a first axis, said outlet port being connected in fluid communication with at least one lubricating conduit of said engine; an oil reservoir connected in fluid communication with said inlet port; an output shaft of said engine supported by said engine for rotation about a second axis and connected in torque transferring relation with said rotor of said oil pump, said first and second axes being displaced from each other by a preselected distance; a sleeve supported for rotation about said second axis, said sleeve being connected in torque transferring relation between said output shaft and said rotor of said oil pump; a first torque transferring protrusion attached to said output shaft and extending in a direction parallel to said second axis; and a second torque transferring protrusion attached to said sleeve, whereby rotation of said first torque transferring protrusion about said second axis causes said first torque transferring protrusion to exert a force against said second torque transferring protrusion, said force causing said sleeve to rotate about said second axis, said first torque transferring protrusion comprising a first pair of pins, said second torque transferring protrusion comprising a second pair of pins.
