| 摘要 |
<p>The present invention aims to decrease actuator failures by the utilization of an internal ventilation system in the diaphragm / piston spring brake actuators used in vehicles such as trucks, busses and trailers. The internally ventilated diaphragm / piston spring brake actuator consists of the following main elements: aluminum piston (1), aluminum pipe (2), spring chamber (3), service chamber (5), piston valve (6), piston valve O-ring (8), piston valve steel ball (9), exhaust hole (10), air entry hole (11), air passage (12), plug (13), air entry holes (14), sealing (15), exhaust bore (16), pressurized air O-ring (17).</p> |
