Abstract
A rotary vane pump including a housing, and a motor. The motor includes a shaft which is coupled to a rotor. The rotor defines a plurality of slots. A plurality of free moving vanes are disposed within the slots. In one example, the rotor is formed from a first material and the plurality of vanes are formed from the first material and impregnated with a second material. The first material can be a carbon material. The second material can be a resin material, an antimony material, a copper material, or a silver material.
Claims20
A rotary vane pump comprising:
- a) a motor having a motor shaft;
- b) a pump body mounted to the motor;
- c) a rotor coupled to the motor shaft and disposed within the pump body;
- and
- d) a plurality of vanes slidably received into slots defined within the rotor;
- e) wherein, the rotor and the plurality of vanes are formed from at least a first material, wherein, for the plurality of vanes, the first material is impregnated with a second material such that the second material is 5% by weight.
A rotary vane pump comprising:
- a motor having a motor shaft;
- a pump body mounted to the motor;
- a rotor coupled to the motor shaft and disposed within the pump body;
- and
- a plurality of vanes slidably received into slots defined within the rotor;
- wherein, one or both of the rotor and the plurality of vanes is formed from a first material and impregnated with a second material;
- wherein the first material associated with one or both of the rotor and the plurality of vanes has an initial pre-impregnated porosity of at least 5% by volume and is impregnated with the second material to have a post-impregnated porosity of less than 5% by volume.
A rotary vane pump comprising:
- a rotor defining a plurality of slots;
- and
- a plurality of vanes slidably received into the slots;
- wherein, the plurality of vanes and the rotor are both formed from a carbon material that has been impregnated with a resin material such that the resin material is 5% by weight and the carbon material is up to 95% by weight.
A portable heater comprising;
- a) a housing;
- b) a fuel tank supported by the housing;
- c) a burner assembly located within the housing;
- and
- d) a rotary vane pump being located within the housing and arranged to deliver fuel from the fuel tank to the burner assembly, wherein the rotary vane pump comprising:
- a motor having a motor shaft;
- a pump body mounted to the motor;
- a rotor coupled to the motor shaft and disposed within the pump body;
- and
- plurality of vanes slidably received into slots defined within the rotor;
- wherein, the rotor and the plurality of vanes are formed from at least a first material, wherein, for the plurality of vanes, the first material is impregnated with a second material such that the second material is 5% by weight.
