Title: Engine brake device
Inventor: KAWASAKI HISASHI
IPC: F01L13/06
Filed: 1989-08-09
Abstract: PURPOSE:To provide proper engine brake without the sacrifice of engine confidence by installing a directional control valve which feeds pressure oil fed from a pressure control device to a cylinder device in a compression process only. CONSTITUTION:A directional control valve 32 and a pressure control device 34 for engine brake are provided between the driving hydraulic circuit of a cylinder device 23 for engine brake. the pressure control device 34 for engine brake is constructed so that pressure oil may be fed to the directional control valve 32 when engine brake is required. The directional control valve 32 is constructed so that he pressure oil from the pressure control device 34 may be fed to the cylinder device 23 in the compression process of a diesel engine 11 in cooperation with a cam 20 to discharge pressure oil in any of processes other than compression. Since the force working upon a locker arm 21, a push rod 22, the cam 20, a cam shaft 19, etc. is only the resistance working upon when the directional control valve 32 is operated, it is possible to prevent the decrease in durability of these components.

Title: Damper mechanism and damper disk assembly
Inventor: HASHIMOTO HIDEKI
IPC: F16F15/129
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To suppress a fact that an excessive press is exerted on a member on the output side and to generate stable hystersis torque by a method wherein the member on the output side of a damper is axially movably engaged with an output hub and axially movably situated following movement of a hub flange. SOLUTION: When the power of an engine is inputted to a clutch disc assembly 1, a torsion spring 7 at a low rigidity damper 8 is compressed in a range of torque being low, second stage torsion springs 5 and 6 at a high rigidity damper 28 are compressed in a range of torque being high, and torque is transmitted to an output hub 4 from an input rotary body 2. Further, when torque is increased, the rotation body 2 on the input side and a hub flange 3 are relatively rotated, and wear is progressed. The hub flange 3 and a fixed plate 9 are pressed through the force of a cone spring, bus since the operation plate of the low rigidity damper 8 is slidably engaged with an engaging groove 41, it is prevented from occurring that a press force is excessively exerted.
