Title: Joseph F Dolinar, Jr: Innovator in Gear Pump Technology

Introduction

Joseph F Dolinar, Jr. is an accomplished inventor based in Severna Park, MD (US). He is known for his innovative contributions to gear pump technology, particularly in reducing fluid-borne noise. His work has significant implications for various applications where noise reduction is critical.

Latest Patents

Dolinar holds a patent for a gear pump with reduced fluid-borne noise. This invention features a crescent internal gear pump that achieves improved sealing against the backflow of fluid while significantly reducing noise levels. The design increases the number of teeth on the ring and pinion gears, which form discrete volumes of pumped fluid against a crescent-shaped member. By reducing the size of the teeth, Dolinar's design allows for an increase in the angular extent of the crescent-shaped insert, resulting in a minimum of nineteen discrete volumes for each gear. This reduction in noise is accompanied by an increase in the fundamental frequency of the remaining noise, making it easier to attenuate through acoustic filtering and isolation.
