Reg Technologies Inc. & REGI U.S., Inc. Announce Device that Reduces Temperature in RadMax™ Moving Parts

Sep 29, 2011, 06:00 ET from Reg Technologies Inc.

VANCOUVER, British Columbia, Sept. 29, 2011 /PRNewswire/ -- REGI U.S., Inc. (OTC BB: RGUS, Frankfurt Stock Exchange: RGJ) and Reg Technologies Inc. (TSX Venture Exchange: RRE.V, OTC BB: REGRF) are pleased to announce that they have integrated a rotary union into the RadMax™ fabrication process, to reduce temperature in the RadMax™ demonstration model.

Robert Grisar, Vice President of Engineering for REGI U.S., Inc. said, "This device allows us to provide continuous high-pressure lubrication and cooling oil to moving and rotating parts of RadMax, thus allowing the engine to operate at a lower temperature. Oil is injected by this device into a hollow driveshaft, with exit ports inside the rotor. This in turn allows us to use lighter components made from Aluminum which further reduces the weight of the engine."

A detailed thermodynamic analysis of the patented RadMax engine was performed last year in conjunction with Belcan Engineering Services of Phoenix, AZ. As a result, integration of the rotary union was needed to provide lubrication oil to internal components. Without this device, the internal engine heat would make adoption of aluminum components impossible. By reducing heat, and weight, this leads to enhanced fuel economy in every RadMax™ application.

This integration was one of the fabrication steps that were described in the RadMax™ test and certification process presented in our March 8, 2011 news release.

A picture of the rotary union is available on the Companies' respective websites at (Reg Technologies Inc.) and (REGI U.S., Inc.).  The following are direct links:


Reg Technologies Inc. and REGI U.S., Inc. are developing for commercialization an improved axial vane type rotary engine known as the Rand Cam™/RadMax™ rotary technology used in the revolutionary design of lightweight and high efficiency engines, compressors and pumps. The RadMax™ engine has only two unique moving parts, the vanes (up to 12) and the rotor, compared to the 40 moving parts in a simple four-cylinder piston engine.   This innovative design makes it possible to produce up to 24 continuous power impulses per one rotation that is vibration-free and extremely quiet.   The RadMax™ engine also has multi-fuel capabilities allowing it to operate on fuels including gasoline, natural gas, hydrogen, propane and diesel.  For more information, please visit   or
