HJS Valvulas de Escape de Acionamento

The vacuum (pneumatic) operated exhaust valve consists of a double supported pressure plate, a housing com an integrated plate stop e a de metal vacuum actuator. The double supported pressure plate e the patented axle suspension allows a noncontact positioning of the pressure plate in the housing. The special design of the exhaust valve ensures a muito high tightness e compared to conventional exhaust valves, the vibration noise is reduced best possible. The pneumatic activation of the exhaust valve can be performed directly on the intake manifold, an additional "vacuum storage" is not needed. The exhaust valve is opened in the pressure-less situation e the opening angle can be adjusted manually.
