US Patent:
20200200284, Jun 25, 2020
Filed:
Dec 18, 2019
Appl. No.:
16/719629
Inventors:
Joseph Ledvora - Wheaton IL, US
Thomas J. Davern - St. Charles IL, US
James E. Pearson - Downers Grove IL, US
Assignee:
Robertshaw Controls Company - Itasca IL
International Classification:
F16K 11/085
F16K 5/04
Abstract:
Embodiments of a multi-port multi-plane valve are provided. The multi-port multi-plane valve includes a housing which defines an internal cavity. The housing further includes a plurality of ports in which each port lies within one of two planes that are normal to each other. Each of the plurality of ports is in communication with the internal cavity. A shell body is rotatably disposed within the internal cavity and provides selectable fluid communications between the ports. A seal member is also provided which has a plurality of openings and surrounds the shell body. At least one flow enhancer channel may be included to reduce the pressure drop occurring on one side of the valve when controlling flow paths on the other side of the valve.

Integrated Flow Check For Water/Coolant Valves

US Patent:
20200173569, Jun 4, 2020
Filed:
Nov 14, 2019
Appl. No.:
16/684215
Inventors:
Michael J. Koch - Roselle IL, US
Thomas J. Davern - St. Charles IL, US
James E. Pearson - Downers Grove IL, US
Assignee:
Robertshaw Controls Company - Itasca IL
International Classification:
F16K 15/18
F16K 11/10
Abstract:
A multi-port valve is provided. The multi-port valve includes a housing which defines an internal cavity. The housing further includes a plurality of ports. Each of the plurality of ports is in communication with the internal cavity. A valve member is rotatably disposed within the internal cavity. A seal member is also provided between the internal cavity and at least one of the ports. A check valve assembly is also provided in fluid communication with at least one of the ports to provide an additional checked flow therefrom or a checked flow therethrough. Temperature, pressure, and/or flow sensors may also be provided.

Multi-Port Valve

View page
US Patent:
20180292016, Oct 11, 2018
Filed:
Apr 4, 2018
Appl. No.:
15/945173
Inventors:
Joe Ledvora - Wheaton IL, US
Philip C. Hawken - Darien IL, US
Thomas J. Davern - St. Charles IL, US
Assignee:
Robertshaw Controls Company - Itasca IL
International Classification:
F16K 11/074
Abstract:
A multi-port valve is provided. The multi-port valve includes a housing which defines an internal cavity. The housing further includes a plurality of ports. Each of the plurality of ports is in communication with the internal cavity. A shell body is rotatably disposed within the internal cavity. A seal member is also provided which has a plurality of openings and surrounds the shell body such that it circumscribes the shell body within the internal cavity.

Bi-Directional Air Flow Damper Having Uni-Directional Synchronous Motor

View page
US Patent:
20060219971, Oct 5, 2006
Filed:
Mar 31, 2005
Appl. No.:
11/096244
Inventors:
James Pearson - Downers Grove IL, US
Robert Van der Linde - Aurora IL, US
Thomas Davern - St. Charles IL, US
Assignee:
Robertshaw Controls Company - Richmond VA
International Classification:
F16K 1/22
US Classification:
251305000
Abstract:
A damper assembly that produces bi-directional damper door movement from a single-direction motor is provided. Bi-directional rotation of the damper door is enabled by a cam slot on an end of the damper door that is engaged by a motor-driven drive cam having a drive pin extending into the cam slot. As the single-direction motor collectively rotates the drive cam and the drive pin, the drive pin reciprocates within the cam slot. This causes sealing flanges and the damper from the damper door to alternatively engage under a positive pressure and disengage from one another as the damper door is rotated bi-directionally.

Appliance Timer Mechanism Utilizing Snap Action Switching

View page
US Patent:
20060163044, Jul 27, 2006
Filed:
Jan 21, 2005
Appl. No.:
11/040884
Inventors:
James Pearson - Downers Grove IL, US
Robert Van der Linde - Aurora IL, US
Thomas Davern - St. Charles IL, US
Assignee:
Robertshaw Controls Company - Richmond VA
International Classification:
H01H 19/00
US Classification:
20001100R
Abstract:
A motor driven appliance timer utilizing a cam program disk and snap action switches is provided. The motor may be externally energized, or may be energized based on integrated electronics within the appliance timer. Rotation of the program disk by a user to allow selection of a desired appliance cycle is accommodated by a clutch subassembly that allows bidirectional rotation of the program disk without requiring that the user pull or push the control shaft before rotating the program disk. The timer of the present invention may utilize either impulse or constant drive mechanisms to rotate the program disk. The use of snap action switches minimizes the possibility of tack weld failures due to switch teasing.

Flow-Through Rotary Damper Providing Compartment Selectivity For A Multi-Compartment Refrigerator

View page
US Patent:
20050011218, Jan 20, 2005
Filed:
Jul 15, 2003
Appl. No.:
10/620104
Inventors:
James Pearson - Downers Grove IL, US
Thomas Davern - St. Charles IL, US
Paul Tuma - Lombard IL, US
Assignee:
Robertshaw Controls Company - Richmond VA
International Classification:
F25D017/04
F24F007/00
F24F013/06
F24F013/08
US Classification:
062407000, 062186000, 454286000
Abstract:
A flow-through rotary damper assembly providing highly efficient, essentially laminar fluid flow therethrough is provided. The rotary damper assembly includes a cylindrical outer body and a cylindrical inner body that are rotatable in relation to one another. The outer body defines apertures in relation to one another to allow fluid flow without requiring fluid direction change. The inner body defines a flow passage having inlet and outlet apertures that may be aligned with the apertures of the outer body to allow fluid flow therethrough, or may be rotated out of alignment to block fluid flow. The outer body includes an aperture on one end to allow fluid flow to a third compartment. The inner body also includes an end aperture that may be aligned therewith. The damper provides selectable fluid flow between each of the compartments depending on the relative position of the cylindrical inner body member.
