Document Type and Number:
WIPO Patent Application WO/2016/139923
Kind Code:
A1
Abstract:
The present invention addresses the problem of simplifying a portion of an oil supply channel, such portion being formed in a cylinder block. This oil supply device (200) is provided with a cylinder block (2), an oil pan (3), an oil pump (81), and an oil filter (82). A wall of the oil pan (3) is connected to a wall of the cylinder block (2). The oil filter (82) is mounted onto the oil pan (3), and an upstream oil supply channel (71), through which oil filtered by the oil filter (82) flows, is formed in the oil pan (3). A downstream oil supply channel (72) that includes a main gallery (74) extending in a cylinder bank direction is formed in the cylinder block (2). A first communication channel (73a) creating communication between the main gallery (74) and the upstream oil supply channel (71) is formed in the wall of the cylinder block (2) and the wall of the oil pan (3).
