Electrically driven air pump having friction-fit, air-tight seal joints

An electrically driven air pump comprising:

• a housing having first and second sections;
• a pump mechanism in said first section;
• an electric motor in said second section in driving engagement with said pump mechanism;
• first and second end covers sealingly on said first and second sections of the housing, respectively;
• elastomer means supporting said electric motor in said second section of the housing;
• said pump mechanism comprising a rotor wheel driven by said motor, and a stator wheel adjacent to said rotor wheel;
• and
• a seal connection between said first cover and both said stator wheel and said first section of the housing, said first cover, said stator wheel and said first section of the housing being made of plastic material and said seal connection comprising means providing an air-tight friction-fit between said first cover and said stator wheel and housing.
