Title: Innovations by John F Bowbin

Introduction

John F Bowbin is a notable inventor based in Elmhurst, IL (US). He has made significant contributions to the field of fluid power technology, holding a total of 3 patents. His work focuses on enhancing the functionality and efficiency of piston and cylinder devices.

Latest Patents

One of Bowbin's latest patents is the "Cylinder locking apparatus." This innovative locking apparatus is designed for a piston and cylinder device, featuring a locking plunger connected to the piston. The plunger is strategically placed between the piston and an end cap, utilizing a sleeve that carries multiple radially movable ball bearings. As the piston approaches an extreme position, the ball bearings engage with a spring-loaded locking plug, effectively locking the piston in place when fluid pressure is absent. This design ensures that the piston remains secure until pressurized fluid is applied to release it.

Another significant invention is the "Expandable cushion plunger for piston and cylinder devices." This plunger includes a cushion sleeve mounted on a piston rod, which floats in relation to the rod. The sleeve's skirt is exposed to cushioning fluid within the cylinder. As the piston nears the end of its stroke, the sleeve enters a fluid exit port, trapping fluid and slowing the piston’s travel. The design allows for smooth deceleration, preventing impact as the piston comes to rest against the cylinder head.
