ABSTRACT:
A liquid forced-feed apparatus, such as a steam trap or pump-trap combination, simplified in construction by decreasing the number of component parts, and capable of switching a change-over valve smoothly with reduced buoyancy. A float, a change-over valve and a snap mechanism are built in a hermetic vessel. The snap mechanism includes a float arm which rotates around a first shaft, a sub-arm which rotates around a second shaft, a spring bracket section formed on the float arm, a spring bracket section formed on the sub-arm, and a reversible plate spring disposed between the spring bracket sections. The float is connected to the float arm, and the change-over valve is connected to the sub-arm.
