초록 ▼

A pump includes a housing defining a cavity, at least one bore, a bore inlet, and a bore outlet. The bore extends from the cavity to the outlet and the inlet communicates with the bore at a position between the cavity and the outlet. A crankshaft is mounted in supports and has an eccentric portion disposed in the cavity. The eccentric portion is coupled to a piston so that rotation of the crankshaft reciprocates the piston in the bore between a discharge position an intake position. The bore may be offset from an axis of rotation to reduce bending of the piston during crankshaft rotation. During assembly of the pump, separate parts of the housing can be connected together to facilitate installation of internal pumping components. Also disclosed is a method of reducing vapor lock by mixing vapor and liquid portions of a substance and introducing the mixture into a piston bore.

[ We claim:] [1.] A pump comprising:a crankshaft having opposite end portions and an eccentric portion between the end portions;a housing defining a cavity, an outlet, at least one bore extending between the cavity and the outlet, and at least one inlet communicating with the bore and with an inlet chamber, the eccentric portion of the crankshaft being in the cavity and the end portions of the crankshaft being rotatably coupled to the housing;a piston having a base disposed in the cavity and a head disposed in the bore, the base of the piston being coupled to the eccentric portion of the crankshaft such that rotation of the eccentric portion in the cavity reciprocates the piston head in the bore to provide discharge from the bore through the outlet and intake to the bore through the inlet;a valve structure disposed to open and close the outlet in response to movement of the piston head during the discharge and the intake;a magnetic member coupled to the crankshaft for magnetically coupling the crankshaft with an external magnetic field capable of rotating the crankshaft;at least one cover containing the magnetic member and defining the inlet chamber; andan electromagnetic stator mounted to the cover, the electromagnetic stator being magnetically coupled to the magnetic member to rotate the magnetic member and the crankshaft.
