Amendment May 7, 1980 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] The head wall member has an air supply hole connected to an external high-pressure gas supply source and a valve operating chamber equipped with a check valve mechanism inside the air supply hole, An intake /exhaust hole opening at the bottom of the valve mechanism is inserted through the valve mechanism so that the inside of the cylinder case housing a piston with a spring tensioned therein is communicated with the valve operating chamber, and at the time of exhaust, it is communicated with the outside through the intake/ exhaust hole. An air cylinder device is constructed by providing an open exhaust hole, and connecting the exhaust hole with an intake and exhaust hole provided in the bottom wall member of the cylinder case and communicating with the inside of the cylinder case. The housing of the exhaust brake main body, which is connected and fixed to the lower surface of the wall member, is connected to the bottom wall member of the cylinder case in a direction substantially perpendicular to the exhaust flow passage, which has connection walls with the exhaust pipe protruding from the left and right ends of the housing. An exhaust brake device that includes a reciprocating plate-shaped valve member that is attached to the vicinity of the tip of a penetrating piston rod, and opens and closes an exhaust flow passage by moving the valve member up and down,
A discharge hole 17 is separately provided which communicates the annular groove 16 provided in the bottom wall member 5 of the air cylinder device and between the seal 15 and the bush 14 on which the piston rod slides with the outside. Features a sliding exhaust brake device. Amendment May 23, 1980 The scope of claims for utility model registration is amended as follows.

Claims (1)

[Scope of utility model registration request] The head wall member has an air supply hole connected to an external high-pressure gas supply source and a valve operating chamber equipped with a check valve mechanism inside the air supply hole, and is opened at the bottom via the check valve mechanism. An air supply/exhaust hole is provided through the cylinder case to communicate the interior of the cylinder case housing a piston with a spring tensioned therein to the valve operating chamber, and an exhaust hole is provided that opens to the outside through the air supply/exhaust hole during exhaust. The air cylinder device is configured by branching the exhaust hole midway and communicating with an air supply and exhaust hole provided in the bottom wall member of the cylinder case and communicating with the inside of the cylinder case, and connected and fixed to the lower surface of the bottom wall member. The housing of the exhaust brake main body is arranged so that the tip of the piston rod passes through the bottom wall member of the cylinder case in a direction substantially perpendicular to the exhaust flow path, which has connecting walls with the exhaust pipe protruding from the left and right tips. An exhaust brake device that includes a reciprocating plate-shaped valve member that is attached nearby and opens and closes an exhaust flow passage by moving the valve member up and down,
A discharge hole 17 is separately provided which communicates the annular groove 16 provided in the bottom wall member 5 of the air cylinder device and between the seal 15 and the bush 14 on which the piston rod slides with the outside. Features a sliding exhaust brake device.
