Uv module

Abstract

A UV module of this invention has connection block (optional), connection end cap, shutter, and exhaust end cap assemblies. The connection block has doweled or tapered bayonets for facilitated installation and removal of the UV module. The connection end cap has a drive train with sleeve bearings and/or torque limiting clutches. Each of the sleeve bearing cooperates with a poppet valve in the connection block assembly to assure fluid-tight integrity during assembly and disassembly. Each of the clutches allows for facilitated shutter synchronization and helps prevent drive train breakdown. The shutter assembly may include a novel coolant flow path cross over and/or improved positive and negative positive and negative retainers to eliminate or greatly reduce shutter binding. The shutter end caps may include coolant flow paths and mate with the shutters to achieve a fluid-tight integrity.
