Abstract
An inverted bucket steam trap having a two lever (30, 34) linkage mechanism between the bucket (18) and the valve member (28) which engages a valve seat (26) through which condensate is discharged. The first lever is connected to the bucket and the second lever carries the valve member. The linkage mechanism is arranged such that the second lever initially undergoes pivotal movement to disengage the valve member from the valve seat and then translatory movement to the fully open position of the valve.

An inverted bucket steam trap comprising:
- a body having a float chamber;
- an inverted bucket movable within said float chamber;
- supply means in fluid communication with the interior of said bucket for supplying steam to said bucket causing said bucket to float and for supplying condensate to said float chamber causing said bucket to sink;
- discharge means in fluid communication with said float chamber through a valve seat for discharging condensate from said float chamber;
- a valve member movable into and out of engagement with said valve seat;
- and coupling means between said valve member and said bucket for moving said valve member in response to movements of said bucket, said coupling means including a first lever connected to said bucket and mounted for pivotal movement about a first axis and a second lever carrying said valve member and mounted for pivotal movement about a second axis and for translatory movement away from said second axis along a predetermined third axis, said first and second levers coupled together at a point which moves about said first and second axes.
