DOUBLE-LINK PISTON CRANK MECHANISM FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/025683
Kind Code:
A1
Abstract:
The opening (35a) on one end side of a pin-boss oil passage (35) opens to the inner-circumferential surface of a pin boss part (14) of an upper link (3), while the opening (35b) on the other end side thereof opens to the outer-circumferential surface of the pin boss part (14) of the upper link (3). A lower-link oil passage (36) has an opening (36a) on one end side thereof which opens to a lower-link (2) pin-boss-facing surface (33) facing the outer-circumferential surface of the pin boss part (14) of the upper link (3), and an opening (36b) on the other end side thereof which opens to a crank-pin-bearing surface (37). The lower-link oil passage (36) is formed so as to point, when at a prescribed crank angle, to an end edge on one end side of the upper link (3), among the end edges of the other-end-side opening (35b) of the pin-boss oil passage (35).
