Abstract
A pump comprising a lower housing, a diaphragm assembly, an upper housing, a valve housing, and an o-ring is provided. The diaphragm assembly is positioned adjacent to the lower housing. The upper housing is positioned adjacent to the diaphragm assembly and includes an inlet chamber and an outlet chamber separated by a ring. The valve housing is positioned between the upper housing and the diaphragm assembly, encloses the inlet chamber and the outlet chamber, and includes a cutout in contact with the ring. The ring includes raised outer walls to receive the cutout and the o-ring is positioned between the raised outer walls of the ring and secured between the raised outer walls by the cutout.
Claims19
A pump comprising:
- a lower housing;
- a diaphragm assembly positioned adjacent to the lower housing, the diaphragm assembly including a lip portion;
- an upper housing including an inlet chamber and an outlet chamber separated by a ring;
- a valve housing positioned between the upper housing and the diaphragm assembly and enclosing the inlet chamber and the outlet chamber, the valve housing including a dividing wall in contact with the ring, the ring including raised outer walls to receive the dividing wall;
- an o-ring positioned between the raised outer walls of the ring and secured between the raised outer walls by the dividing wall;
- a plurality of inlet valves and a plurality of outlet valves, each of the plurality of inlet valves and the plurality of outlet valves including a headed extension corresponding to a respective central aperture;
- and
- a plurality of pump chambers, each pump chamber of the plurality of pump chambers including a single one of the plurality of inlet valves and a single one of the plurality of outlet valves, and the plurality of pump chambers being isolated from one another by the lip portion,
- wherein the dividing wall extends away from the plurality of pump chambers beyond each of the plurality of outlet valves.
6 more elements
A pump, comprising:
- a diaphragm assembly including a lip portion;
- and
- a valve housing coupled to the diaphragm assembly, the valve housing defining a plurality of pump chambers on a first side of the valve housing and including a plurality of disc-shaped inlet valves and a plurality of disc-shaped outlet valves,
- the valve housing further including a dividing wall positioned between the plurality of disc-shaped inlet valves and the plurality of disc-shaped outlet valves on a second side of the valve housing opposite the first side, the dividing wall extending away from the second side of the valve housing past the plurality of disc-shaped inlet valves and the plurality of disc-shaped outlet valves,
- wherein each of the plurality of pump chambers includes only one of the plurality of disc-shaped inlet valves and only one of the plurality of disc-shaped outlet valves, and the lip portion extends around a perimeter of each of the plurality of pump chambers so that each pump chamber is isolated from one another.
