Title:
DECOMPRESSION BRAKE
Document Type and Number:
Japanese Patent JP2004068660
Kind Code:
A
Abstract:

To provide a decompression brake adaptable for a vehicular engine, suppressing an increase in diameter of a boss portion of a rocker arm.

The braking force of the decompression brake is created by turning an eccentric cam 16 laid between a rocker shaft 11 and the rocker arm 12 for changing the rocking center of the rocker arm 12 to adjust the lift amount of an exhaust valve on a cam base circle. The outer face of the rocker shaft 11 has a stepped smaller diameter at a mounting portion of an eccentric bush 16 to form a groove 15 which receives an inner periphery portion of the eccentric bush 16. The rocker shaft 11 is mounted with the eccentric bush 16 partially embedded therein, thereby suppressing an increase in diameter of the boss portion of the rocker arm 12 with the mounting of the eccentric bush 16.
