Its inner cavity is divided into the piston of epicoele and cavity of resorption, and epicoele, cavity of resorption accommodate nitrogen, lubricating oil respectively, and piston is equipped with several sealing rings
And sealing ring；The bottom of one end connection accumulator shell of the oil pipe, the other end connect adapter；First check valve
One end leads to turbocharger, the other end connects adapter；It is one end access to engine lubricating system of the second one-way valve, another
One end connects adapter.
Above-mentioned technical proposal can advanced optimize are as follows:
1 sealing ring is set in the middle part of the piston, and top, the lower section of sealing ring respectively set 2 sealing rings.
