A fluid spray device system () that maintains a resultant fluid discharge, or a material onto which the resultant fluid is discharged, within a predetermined range of a set-point temperature by regulating the flow rate of a throttling gas using a proportional valve (). The resultant fluid has throttling gas and cryogenic fluid components. Both the throttling gas and cryogenic fluid are preferably supplied from a single tank () and the cryogenic fluid supply is pressure-regulated and includes a triaxial delivery hose () having a return line with a back-pressure regulator ().

Apparatus and method for controlling the temperature of a cryogen

A method and apparatus for discharging a temperature-controlled flow of a resultant fluid () containing a throttling gas and cryogenic fluid onto a material () for the purpose of maintaining the temperature of the material within a desired temperature range and below the glass transition temperature of the material during machining. Also disclosed is an apparatus and method for deburring or deflashing a machined material by discharging a temperature-controlled flow of a resultant fluid () onto a machined material () to harden the burrs (), then brushing the material () to remove the hardened burrs ().

Apparatus and method for machining polymers with controlled croygenic cooling

A coolant delivery system and method for maintaining a temperature within a predetermined range of a set-point temperature in a vessel into which a coolant gas is discharged or a temperature of a material onto which the coolant gas is discharged. The coolant gas results from the mixing of a supply gas with a cryogen. Temperature regulation is provided by regulating the flow rate of a cryogen using a proportional valve, while providing an essentially constant flow rate of a supply gas.
