Variable Reluctance Electric Motor Driven Vacuum Pump
US Patent:
5246349, Sep 21, 1993
Filed:
Dec 18, 1992
Appl. No.:
7/995649
Inventors:
Richard G. Hartog - Michigan City IN
Assignee:
Sullair Corporation - Michigan City IN
International Classification:
F04F 3504
US Classification:
417371
Abstract:
A motor driven compressor is provided with a means through which the internal portion of the motor is maintained at a pressure below atmospheric pressure when the compressor is operating. This reduced pressure within the motor reduces the windage losses of the motor and reduces the noise generated which as a result emanates from the motor. The present invention is most suitable for use in association with a variable reluctance motor connected in torque provided relation with a screw compressor, wherein the screw compressor is utilized as a vacuum pump. The internal portion of the motor is connected in fluid communication with the suction port of the vacuum pump and this association reduces the pressure within the motor and reduces both the windage losses and the noise emanating from the motor.
Pressurized Purging Of A Liquid Drain For A Vacuum System
US Patent:
5096598, Mar 17, 1992
Filed:
Feb 26, 1990
Appl. No.:
7/485192
Inventors:
Roger P. Pecen - Michigan City IN
Richard G. Hartog - Michigan City IN
Richard G. Hartog - Michigan City IN
Assignee:
Sullair Corporation - Michigan City IN
International Classification:
B01D 1700
US Classification:
210741
Abstract:
The present invention is directed to an improved purging of a liquid drain system for a liquid separator used in a moisture laden process vacuum system wherein the liquid separated from the flow stream by the separator is collected in an accumulator which in turn is periodically pressure purged to quickly remove the liquid contents of the accumulator while such accumulator is out of fluid communication with the liquid separator so that the vacuum process need not be interrupted. A pressure responsive drain valve is connected between the separator and the accumulator. The pressure used to purge the accumulator also activates the normally opened drain valve to inhibit the fluid flow between the separator and the accumulator. A pressure responsive drain is connected to the accumulator and opens in response to the increased pressure used to purge the accumulator and close the normally opened drain valve.
