Valve With Dual Rotation Valve Member

View page
US Patent:
2012024, Oct 4, 2012
Filed:
Mar 30, 2011
Appl. No.:
13/076170
Inventors:
Stanley S. Dederich - Batavia IL,
Daniel J. Goray - Gilberts IL,
Assignee:
SCHNEIDER ELECTRIC BUILDINGS, LLC - Loves Park IL
International Classification:
F16K 31/54
F16K 27/00
F16K 5/00
US Classification:
251248, 251304, 251366
Abstract:
A valve with a dual rotational valve member is provided. The valve includes a first valve member and a second valve member. An actuation arrangement is operably positioned between the first valve member and the second valve member to rotate the first valve member in a first direction and the second valve member in a second direction opposite the first direction. This counter-rotation of the first and second valve members selectively aligns or misaligns a pair of flow ports of the first valve member with a pair of flow ports of the second valve member. When the pairs of flow ports are aligned, the flow path of the valve allows for straight through flow of a fluid through the valve thereby decreasing turbulence, back pressure, and noise.

US Patent:
4539556, Sep 3, 1985
Filed:
Apr 15, 1983
Appl. No.:
6/485234
Inventors:
Stanley S. Dederich - Naperville IL
George A. Schoenfelder - Downers Grove IL
William M. Koster - Bartlett IL
Assignee:
Pittway Corporation - Aurora IL
International Classification:
G08B 2900
G08B 1710
US Classification:
340515
Abstract:
A battery-powered photoelectric smoke detector periodically samples the air in a smoke chamber. A manually-operated test button is provided for simulating smoke to test the device. The sampling frequency is determined by a first resistance. A frequency changing circuit includes a test switch, the movable contact of which is coupled to the test button and is responsive to operation thereof for connecting it parallel with the first resistance the series combination of a diode and a second resistance for increasing the sampling frequency. Means are provided for back-biasing the diode to disable the frequency changing circuit when the detector detects smoke.
