Vacuum motor airflow series/parallel switching apparatus
a vacuum motor and airflow technology, applied in mechanical equipment, machines/engines, servomotor components, etc., can solve the problems of limited maximum airflow to approximate the flow capability of one motor, disadvantage of total lift approximating the capability of a single motor, and inability to effectively switch between series a plurality of vacuum motors

Benefits of technology
[0003]The current invention allows for transitioning a plurality of vacuum motors between an air series and an air parallel configuration. A switching valve is positioned between the first vacuum motor outlet and the second vacuum motor inlet so that when the switching valve is open, the vacuum motors are configured air series, and when the switching valve is closed, the vacuum motors are configured air parallel. When the vacuum motors are configured in air parallel, the total intake air is divided with some
Problems solved by technology
The advantages of air series arrangement is high lift capability at highly restricted or sealed conditions, but the disadvantage is that maximum airflow is limited to approximate flow capability of one motor.
The advantages of air parallel arrangement is high total airflow approximating the total sum flow of all motors, with the disadvantage of total lift approximating the capability of a single motor.
There is currently no effective mechanism by which a plurality of vacuum motors may be readily switched between series and parallel configurations.

Embodiment Construction
[0006]FIGS. 1 and 2 depict a system capable switching at least a first vacuum motor 1 and a second vacuum motor 2 between parallel and series configurations. Air enters the system from a device inlet 3 into a first chamber 10. Device inlet 3 serves as an air intake, and is sufficiently sized to allow full airflow potential of the sum of first vacuum motor 1 and a second vacuum motor 2. First chamber 10 comprises a first chamber outlet 11 provided in communication with an inlet to first vacuum motor 1. An air outlet 12 to first vacuum motor 1 is in turn connected to a second chamber 20 through a second chamber inlet 21. First chamber 10 additionally is in communication with a first check valve 40, so that first check valve 40 is disposed between first chamber 10 and a third chamber 30. A switching valve 60 is also disposed between second chamber 20 and third chamber 30.
[0007]First chamber 10 and second chamber 20 are permanently sealed from each other. First chamber 10 and third cham...

An apparatus for transitioning at least a first vacuum motor and a second vacuum motor between an air series configuration and an air parallel configuration is provided. The apparatus comprises a controllable switching valve, a first check valve, a second check valve and a plurality of chambers. The switching valve is positioned in communication with the first vacuum motor air outlet and the second vacuum air inlet. The apparatus is configured so that when the switching valve is opened the vacuum motors are configured air series and when the switching valve is closed the vacuum motors are configured air parallel. The first and the second check valves are opened or closed by pressure differential between chambers.
Description
[0001]This application claims the benefit of U.S. Provisional patent application No. 61 / 456,645 filed on Nov. 10, 2010.BACKGROUND OF THE INVENTION[0002]Typically multiple vacuum motors are arranged in one of two ways, either air series or air parallel. The advantages of air series arrangement is high lift capability at highly restricted or sealed conditions, but the disadvantage is that maximum airflow is limited to approximate flow capability of one motor. The advantages of air parallel arrangement is high total airflow approximating the total sum flow of all motors, with the disadvantage of total lift approximating the capability of a single motor. There is currently no effective mechanism by which a plurality of vacuum motors may be readily switched between series and parallel configurations.SUMMARY OF THE INVENTION[0003]The current invention allows for transitioning a plurality of vacuum motors between an air series and an air parallel configuration. A switching valve is positio...
