A device for controlling fluid flow for heating or cooling an associated system is provided. The present invention includes a housing having a flow control member that includes a bendable portion. The flow control member responds automatically to a pressure condition within the housing and opens or closes based on the direction and quantity of fluid flow and does not include any mechanical or electromechanical control components. The bendable portion may include, for example, a convoluted section. The flow control member is in an open position during a mode of operation of the associated system and is in a closed position in another mode of operation of the system.

Hingeless flapper valve for flow control

A carrier is described that adapts an excavator with an dozer blade to a tote bucket or scoop. The excavator carrier rests on the blade at its bottom with the blade serving as the back of the carrier. Dumping capability is provided by pivoting the carrier on mounting pins between a mounting bracket added to the back of the blade at its top and a corresponding mounting bracket on the carrier. A backhoe on the excavator can be used to lift the front of the carrier causing the carrier to pivot on the mounting pin and dump material through the separation of the the carrier and the blade at its bottom. Side plates of the carrier extend beyond the back of the blade in a shearing action to maintain self alignment. Quick separation of the carrier from the excavator blade is obtained by simply removing mounting pins on which the carrier pivots and using the backhoe to move the carrier conversion away from the excavator or backing the excavator away from the carrier.
