He has made significant contributions to the field of engineering, particularly in the development of innovative timing and valve mechanisms. With a total of 2 patents, his work reflects a commitment to enhancing efficiency and functionality in various applications.

Latest Patents

Thornbery's latest patents include a Timer with Delayed Start Capability and a Combination Valve. The Timer with Delayed Start Capability features a timing cam driven at timing speed through a gear train that includes a clutch. This design allows for a delayed start by positioning the timing cam at the start of a cycle, enabling a lever to move a tiltable jackshaft to an active position. The worm gear rotation drives the ratchet back to zero, at which point the clutch is engaged, and normal timing begins. The length of the time delay is determined by the number of ratchet teeth engaged with the worm gear.

The Combination Valve presents a low-cost and versatile method of mounting an evaporator pressure regulator valve (EPR) on a thermostatic expansion valve (TXV). This compact combination valve controls refrigerant flow to the evaporator based on pressure and temperature. The design includes a hollowed-out rider pin and a sleeve of low thermal conductivity to dampen temperature changes and reduce valve hunting. The EPR threads into the TXV outlet, allowing for efficient operation in refrigeration systems.
