Said parallel port is arranged on the side of parallel port seat; The seat front, parallel port of said parallel port seat is installed on the original machine oil filter core device seat of machine oil filter core device, and the machine oil filtering core device is installed at its back side, combines with machine oil filter core device base; The center of said parallel port seat is provided with parallel port base oil export, combines with machine oil outlet coupling on the machine oil filter core device base of machine oil filter core device; One group of parallel port base oil inlet is set on the seat of said parallel port, combines with machine oil import coupling on the machine oil filter core device base of machine oil filter core device; Said parallel port is communicated with any parallel port base oil inlet.
Said parallel port is arranged on the machine oil filter core device shell of machine oil filter core device, and the machine oil chamber that forms with machine oil filter core device shell and element kit is communicated with.
Said electric motor oil switch pump is the time-delay cut-off switch.
Compared with prior art; The present invention has the following advantages: simple and reasonable, can effectively stop or the dry grinding friction when reducing engine cold-start to the infringement of motor, can prolong motor working life; Improve the motor vehicle emission National standard, reduce the maintenance cost of automobile.Be suitable in various lubricating system of IC engine, adopting, comprise the explosive motor of newly making or transforming.
