Title: Dale Ewing: Innovator in Vapor Recovery Systems
Introduction
Dale Ewing is a notable inventor based in Hollidaysburg, PA (US), recognized for his contributions to vapor recovery technology. With a total of five patents to his name, Ewing has made significant advancements in methods that enhance fuel dispensing systems.
Latest Patents
One of Ewing's latest patents is for a vapor recovery pump regulation of pressure to maintain air to liquid ratio. This innovative method operates a vapor recovery system that captures vapors expelled from vehicles during refueling. The system returns these vapors to an underground storage tank through a vapor flow path, which is in fluid communication with an air to liquid regulator valve and a vapor pump. The method includes dispensing fuel into the vehicle while regulating the amount of vapor recovered in proportion to the fuel dispensed. It also involves detecting parameters of the vapor recovery system and maintaining a constant pressure level in a specific portion of the vapor return path.
Another significant patent is the double-walled contained shear valve, particularly designed for fueling environments. This double-walled shear valve facilitates the transfer of fuel from branch or main fuel piping to fuel dispenser piping. It features a containment housing with a shear groove and an inner housing that defines a fuel flow path. The design ensures that an interstitial space is formed between the containment housing and the inner housing, which is separate from the fuel flow path. Additionally, it includes a main poppet valve that is adapted to close the fuel flow path, preventing any fuel flow when necessary.
