US Patent:

7137303, Nov 21, 2006

Filed:

Aug 31, 2004

Appl. No.:

10/930970

Inventors:

Leon P. Janik - Suffield CT, US
Stephen J. Vardion - Glastonbury CT, US
Michael J. Williams - Glastonbury CT, US

Assignee:

Stanadyne Corporation - Windsor CT

International Classification:

G01L 7/16
B01D 35/00

US Classification:

73744, 210 90

Abstract:

A fluid system pressure indicator is adapted for use in fluid systems having a filter element. The fluid system force indicator includes a housing partitioned to be exposed to the fluid system to provide transmission of a mechanical force between these partitioned environments to indicate the fluid pressure. This exterior shape change is such that it can be identified through tactile means not requiring visual identification.

US Patent:

Filed:

Mar 13, 2001

Appl. No.:

09/805757

Inventors:

Stephen Vardion - Glastonbury CT, US

International Classification:

B01D027/00

US Classification:

210/232000

Abstract:

A modular base for a filter assembly includes a header portion defining a cavity for receiving a filter cartridge and a communication module defining fluid pathways to and from the base. Brackets extend from the header portion and include slots. Yokes extend from the communication module to complement the slots. The brackets and received yokes together define pathways into which generally tubular compression limiters are inserted. The compression limiters serve dual functions by retaining the communication module to the header portion and reinforcing the brackets. A sealing grommet disposed between the header portion and communication module enhances the sealed integrity of the base.

International Classification:

B01D 27/00

US Classification:

210299000, 210435000

Abstract:

A drain valve insert employs a stamped sheet metal body to support a threaded nut in an elevated position over the drain opening of a filter cartridge. Multiple fluid flow passages are defined between the polygonal periphery of the nut and the generally cylindrical sheet metal body of the insert. The insert body defines ledges to support the nut at its periphery corners and includes structures that prevent rotation of the nut relative to the insert body. Retaining arms project upwardly from the insert body and are bent over the nut to axially retain the nut seated against the ledges. The insert body and the nut are inexpensively formed in separate automated operations. Assembly of the nut into the insert body may also be automated.

International Classification:

US Classification:

210090000, 210094000, 116266000, 116272000

Abstract:

A filter change indicator includes two indicators visible through a window. The first indicator is disposed in the viewing window in a fixed position. The second indicator covers the first indicator in a first position and is moveable relative to the first indicator to a second position revealing the first indicator. The filter change indicator also includes a spring and flexible diaphragm arranged such that changes in the pressure of a fluid system moves the second indicator to expose the first indicator to provide a visual indication of filter occlusion.
