Pump trap assembly having multiple pivot axes

Abstract

A pump trap assembly with multiple pivot axes. The pump trap assembly includes a mounting bracket for mounting the trap assembly to a structure. A first pivot arm having a length is pivotally mounted to the mounting bracket about a first pivot axis. A second pivot arm having a length is also pivotally mounted to the mounting bracket about the first pivot axis. A spring is used to bias the first and second pivot arms toward each other. A float arm having a length is also pivotally mounted to the mounting bracket about a second pivot axis. The second pivot axis is a distance from the first pivot axis. An actuator is pivotally mounted to the second pivot arm about a third pivot axis. The third pivot axis may be the same as the second pivot axis or may be a distance from the first and second pivot axes. Movement of the float arm in a first direction causes the spring to urge the second pivot arm in the first direction and move the actuator in the first direction. In another embodiment, the second pivot arm may be pivotally mounted to the mounting bracket about a different pivot axis than the first pivot arm. In another embodiment, the float arm may be pivotally mounted to the same pivot axis as the second pivot arm. The pump trap having multiple pivot axes provides for a more compact design than conventional pump traps having only one pivot axis for both the float arm and the pivot arms.
