Abstract
An illustrative embodiment of the present disclosure includes a pump having a rotor and a plurality of vanes. The rotor is attached to a motor that rotates it in first and second directions and is located in a cavity. The plurality of vanes are each pivotally coupled to the rotor so as the rotor rotates, the vanes selectively push fluid from an inlet port out through an outlet port. The plurality of vanes each have an end selected from the group consisting of a lobe, no lobe, and a rod located in the lobe. Each of the plurality of vanes also includes a pivot pin configured to fit in a corresponding receptacle located in the rotor so that each of the plurality of vanes is pivotable with respect to the rotor inside the cavity.
Claims18
A pump comprising:
- a motor assembly;
- a rotor attached to the motor assembly that rotates the rotor;
- a plurality of vanes each pivotally coupled to the rotor so as the rotor rotates, the vanes selectively push fluid to an outlet port;
- a power cord with a power cord outlet that supplies power to the motor assembly;
- wherein the power cord outlet includes at least one receptacle;
- a power cord connector that transmits power from the power cord and to the motor assembly;
- wherein the power cord connector includes a ground pin extending therefrom;
- wherein the ground pin is configured to contact the at least one receptacle of the power cord before any electrical contact is made between the power cord and the power cord connector;
- and
- wherein the ground pin is configured to release from the power cord after the electrical contact has been released.
A pump comprising:
- a motor assembly;
- a rotor attached to the motor assembly that rotates the rotor;
- a connector coupled to the motor assembly to supply power from a power cord to the motor assembly;
- wherein the connector includes a ground pin extending therefrom;
- wherein the ground pin is configured to make contact between the power cord and the motor assembly before any electrical contact.
A pump comprising:
- a motor assembly located within a pump housing for operating the pump;
- a power cord;
- a junction coupled to the motor assembly located in the pump, accessible from exterior of the pump, and selectively attachable to the power cord, to supply power from the power cord to the motor assembly;
- wherein the junction includes a ground pin and at least one electrical contact both extending therefrom;
- and
- wherein the ground pin extends longer than the at least one electrical contact so the ground pin makes contact with the power cord before the at least one electrical contact makes contact with the power cord.
