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.
Claims19
An integrated air pump, comprising:
- a housing open to atmosphere and including an air outlet;
- a high-pressure pump disposed within the housing and in fluid communication with the air outlet, the high-pressure pump including a first motor, a transmission operably coupled to the first motor, and a movable member eccentrically coupled to the transmission assembly;
- a first high-pressure check valve disposed between the high-pressure pump and atmosphere;
- a second high-pressure check valve disposed between the high-pressure pump and the air outlet of the housing;
- a low-pressure pump disposed within the housing and in fluid communication with the air outlet, the low-pressure pump comprising a second motor;
- and
- a low-pressure check valve disposed between the low-pressure pump and the air outlet of the housing, the low-pressure check valve disposed between the second high-pressure check valve and the air outlet.
