<p>A float controllable valve responsive to the level of condensate having a housing with an internal chamber including an input supply opening and a discharge opening. There is a membrane capsule disposed in the interior of the housing and formed with at least a first throttle inlet bore communicative to the interior of the membrane capsule with the internal chamber of said housing at a pressure side. The membrane capsule includes a rigid inlet nozzle extending into the interior of the membrane capsule and has a nozzle bore communicating with the discharge channel. The inlet nozzle has a valve seat in the interior of the membrane capsule between the throttle bore and the nozzle bore. A locking member is slidably disposed and extends into the interior of the membrane capsule and has one end in sealing contact with the valve seat. There is a pivotable lever arm having a float secured at one end and disposed outside of the membrane capsule and having its opposite end pivotably coupled to the housing, said lever arm being pivotably coupled to the opposite end of the locking member. A movable wall portion is formed with a second throttle bore through which said rigid inlet nozzle extends, the wall portion being longitudinal movable with respect to the nozzle and connected to the locking member, so that when the fluid contacts the float and lifts the locking member from the valve seat, a pressure differential is created on both sides of the movable wall portion so that an additional opening force is exerted on said locking element which opens the valve rapidly.</p> |
