US Patent:

41251270, Nov 14, 1978

Filed:

May 12, 1977

Appl. No.:

5/796277

Inventors:

James B. Harter - Tempe AZ

Assignee:

The Garrett Corporation - Los Angeles CA

International Classification:

F16K 1704

US Classification:

137494

Abstract:

A translating piston, fluid pressure valve which utilizes a convoluted, elastomeric diaphragm member both to seal a high pressure area and to selectively control exhaust of pressurized fluid therefrom upon movement of the piston of the valve.

Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ

International Classification:

F01B 1900
F16J 300

US Classification:

92103SD

Abstract:

A diaphragm particularly for rolling-diaphragm type fluid pressure motors. The invention provides greatly improved service life of the motor, particularly under adverse condition in which conventional diaphragms fail quickly.

Filed:

Nov 27, 1989

Appl. No.:

7/441766

Inventors:

James B. Harter - Phoenix AZ

International Classification:

G01F 142

US Classification:

7386162

Abstract:

A multiple orifice flow measuring device includes a housing having a central passage and a shaft passage located above and parallel to the central passage. The central passage contains a pipe adapted to be connected to a gas flow line. Mounted in the shaft passage is a shaft, on which is rotatably mounted a disk having a plurality of orifices of various diameters spaced circumferentially about the disk and selectively registerable in the flow passage of the pipe. Closely fitting around the pipe against the disk is a piston having a annular recess. A spring located in the central passage between the piston and the end of the housing opposite the disk forces the piston against the disk, thereby maintaining it in position. A lever extending from outside the housing into the piston annular recess is pivotally mounted to the housing so that when gas flow is shut off and the outside end of the lever is moved towards the disk, the end of the lever located within the annular recess pushes the piston away from the disk, compressing the spring, thereby releasing the disk for rotation to a different diameter orifice.
