Abstract
A high and low-pressure integrated air pump includes a single housing including an air inlet and an air outlet. A high-pressure pump is disposed within the housing and in fluid communication with the air inlet, and uses a first outlet passage to discharge to the air outlet. A low-pressure pump is also disposed within the housing and in fluid communication with the air inlet, and uses a second outlet passage to discharge to the air outlet.
Claims29
A high and low-pressure integrated air pump, comprising:
- a housing including an air inlet and an air outlet;
- a high-pressure pump disposed within the housing, in fluid communication with the air inlet and in fluid communication with the air outlet via a first outlet passage;
- and
- a low-pressure pump disposed within the housing, in fluid communication with the air inlet and in fluid communication with the air outlet via a second outlet passage, wherein the low-pressure pump is configured to automatically disengage and the high-pressure pump is configured to automatically engage in response to a common signal.
