Claims

[Scope of utility model registration request]

(1) A throttle valve that throttles the exhaust passage of the engine and generates an exhaust braking force; a fluid cylinder that opens and closes the throttle valve; and a fluid cylinder that increases or decreases the amount of expansion and contraction of the cylinder in proportion to the load applied to the engine. An exhaust brake device comprising: a disk for variably controlling the amount of throttle of a throttle valve.

(2) The above-mentioned utility model is configured such that the above-mentioned disk is configured to variably control the stroke length by changing the plate thickness in the direction of increasing load and coming into contact with the extendable end of the piston rod that is moved by the above-mentioned cylinder. An exhaust brake device according to claim 1.

(3) The exhaust brake device according to claim 1, wherein the disc is formed with a spiral surface so as to continuously show the increasing direction of load.

(4) The exhaust brake device according to claim 1, wherein the disc is formed by a stepwise height difference surface so as to show the direction of increase in load in a stepwise manner.
