Abstract
A pump assembly for circulating water in an evaporative cooler is provided. The pump assembly may include a housing which defines a cavity. The pump assembly may also include an impeller received in the cavity of the housing. Further, the pump assembly may include a rod which may be operatively associated with the impeller and extends out of the housing. Moreover, the pump assembly may include a connecting member which is operatively associated with the rod, and may be adapted to be operatively associated with a shaft of a fan assembly incorporated into the evaporative cooler. The connecting member may be adapted to transmit rotary motion of the shaft to the impeller, thereby enabling the pump assembly to circulate water in the evaporative cooler.
Claims8
A pump assembly for circulating water in a swamp cooler having a fan assembly associated with a shaft, the pump assembly comprising:
- a housing having a cavity;
- an impeller received in the cavity, the impeller being operatively connected to the shaft so as to transmit rotary motion of the shaft of the fan assembly to the impeller, and so as to secure an axis of rotation of the impeller in a coaxial relationship with an axis of rotation of the shaft of the fan assembly;
- and a rod operatively associated with the impeller;
- and
- a connecting member operatively associated with the rod,
- the connecting member structured to be operatively associated with the shaft of the fan assembly so as to transmit rotary motion of the shaft to the impeller, and
- the connecting member comprising a first slot adapted to threadably receive the rod, and a second slot adapted to receive the shaft of the fan assembly for allowing coupling of the connecting member to the shaft such that the connecting member rotates in conjunction with the shaft.
A pump assembly for circulating water in a swamp cooler having a fan assembly associated with a shaft, the pump assembly comprising:
- a housing having a cavity;
- an impeller received in the cavity, and
- means for operatively coupling the impeller to the shaft so as to transmit rotary motion of the shaft of the fan assembly to the impeller, and so as to secure an axis of rotation of the impeller in a coaxial relationship with an axis of rotation of the shaft of the fan assembly,
- wherein the coupling means comprises a rod operatively associated with the impeller, said rod having a shaped portion;
- and
- a connecting member operatively associated with the rod,
- the connecting member structured to be operatively associated with the shaft of the fan assembly so as to transmit rotary motion of the shaft to the impeller, and
- the connecting member comprising a first portion complimentarily shaped to receive the shaped portion of said rod, and a second portion adapted to receive the shaft of the fan assembly for allowing coupling of the connecting member to the shaft such that the connecting member rotates in conjunction with tbe shaft.
