Filed:

Feb 21, 2012

Appl. No.:

14/000351

Inventors:

John Hartzell - North Little Rock AR, US
James Cirillo - Cleveland Heights OH, US
Dustin Hromyak - Warren OH, US

Assignee:

PARKER-HANNIFIN CORPORATION - Cleveland OH

International Classification:

F15B 15/00

US Classification:

92 5 R, 295921

Abstract:

A piston-cylinder actuator includes a unique mount for an absolute-position sensor. The mount is made from a bearing material provides a flexible connection between the sensor mount and the cylinder housing. This flexible connection allows the piston rod to deflect naturally, under its own weight or under other laterally-directed forces, while maintaining the distance and perpendicularity between the sensor and the rod surface, within acceptable limits. The sensor mount is made from a bearing material that will allow it to float directly on the rod surface without scuffing or otherwise damaging the rod surface, particularly the markings or other indicia on that surface. Due to the flexible connection between the sensor mount and the cylinder housing, the proper distance between the sensor and the rod surface can be maintained at all times.
