Viscous fluid compound applicator

摘要

A viscous applicator having a chamber for holding viscous fluid such as dry wall compound. A one-way filling valve (31) and a discharge nozzle (26) are located on the chamber. The nozzle (26) is opened and closed using a pull rod (17) connected to a seal (18) on one end. The second end is controlled by a rotatable handle (20) on the applicator main housing. A gas spring (14) is located in the housing and retracts during loading of dry wall compound into the chamber and discharges compound when the discharge nozzle is opened by the pull rod (17). The handle is spring loaded to close the nozzle when released. A hollow push rod (15) connects the gas spring (14) to a dispensing head in the chamber and the pull rod (17) is movable through the push rod (15) and the dispensing head. A series of cam slots (57,58) and followers (63) controls motions of the handle and the pull rod. <IMAGE>
