Claims

[Scope of utility model registration request]

The reciprocating working path of the plate-shaped valve member is connected to the reciprocating working path of the plate-shaped valve member in a direction substantially perpendicular to the exhaust flow path, which has connection walls with the exhaust pipe protruding from both ends thereof. The valve member having the pressure adjustment hole formed therethrough is installed inside the valve member, and is engaged with the distal end side of the piston rod that passes through the partition wall between the air cylinder device and the air cylinder device connected to the upper end of the reciprocating working path, and An auxiliary valve member that engages with the valve member is connected near the tip, and when the valve member closes the exhaust flow path, the auxiliary valve member closes the exhaust pressure adjustment hole and the tip of the piston rod presses the valve member in one direction. On the other hand, in an exhaust brake device in which the exhaust pressure adjustment hole is opened by an auxiliary valve member when the circuit is opened, and the auxiliary valve member engages with the valve member and moves in the other direction, Exhaust pressure adjustment holes 4 ₁ , 4 ₂ are provided on both left and right sides of the bottom wall surface on the side of the valve member 3 across the center of the axis, and the auxiliary valve member 7
A pair of liner members 7 ₁ in the shape of an elliptical cylinder with a small diameter exhaust escape hole 8 in the left and right engaging holes 9 ₁ , 9 ₂ extending through the block members 9 that are connected to each other on the sides and having a longer diameter in the sliding direction. , 7 ₂ are movably fitted into each other with their respective lower end flange walls 7 ₁ ′, 7 ₂ ′ laid on the lower surface of the block member, and when the exhaust flow passage 2 is opened and closed, the The exhaust pressure adjustment hole 4 ₁ of the valve member 3 is controlled by the liner member 7 ₁ , 7 ₂ .
4. A slide-type exhaust brake device characterized in that it is configured to rub the vicinity of and above the surface of the bottom wall where item ₂ is located.
