Title:
OIL PATH STRUCTURE FOR CYLINDER HEAD
Document Type and Number:
WIPO Patent Application WO/2007/135816
Kind Code:
A1
Abstract:
An oil communication path (39b) is formed in a cylinder head(14) of an engine so
as to penetrate through a wall section (39) separating an oil drop hole (38) and
an oil container (41) that are formed in the cylinder head(14). This enables
oil collected in the oil container (41) to be guided to the oil drop hole (38). In
the wall section (39) of the cylinder head (14) are formed an oil supply path (39c)
and a holding hole (39a) for holding a hydraulic tappet (22) operated by oil supplied
from the oil supply path (39c), and the oil supply path (39c) and the oil communication
path (39b) are interconnected via the holding hole (39a). As a result, even if
a part of the oil supplied from the oil supply path (39c) to the hydraulic tappet
(22) leaks to the holding hole (39a), the oil can be discharged using the oil communication
path (39b).
