Abstract: An electrical control panel including an enclosure box being sealed other than at an inlet opening and an outlet opening, a primary electrical component inside the enclosure box and having a first heat exchanger that transfers heat from the primary electrical component, one or more secondary electrical components inside the enclosure box that generate less heat than the primary electrical component, a second heat exchanger attached to the enclosure box and having an internal air passageway that includes an inlet opening and an outlet opening in fluid communication with the respective outlet and inlet openings of the enclosure box and defining therewith a sealed compartment, and one or more diverter elements direct a majority of the heated air from the first heat exchanger to enter the internal air passageway of the second heat exchanger without flowing over at least one of the secondary electrical components.

Abstract: An agricultural harvester includes a grain processing section having a sieve assembly. The sieve assembly is driven in fore and aft oscillation by an eccentric rotation device while permitting side to side movement. A drive arm to the sieve assembly has a connection interface to the eccentric rotation device permitting side to side movement during fore and aft oscillation.

Abstract: The disclosure provides a gear pump rotor assembly that includes a rotor body, a rotor head having a plurality of gear teeth and being connected to the rotor body, at least one connector extending between the rotor body and the rotor head, at least one radial deformation control member that extends into at least one gear tooth of the rotor head and reduces the radial deformation of the rotor head relative to the rotor body when a change in temperature causes radial deformation of the rotor body and rotor head.

Abstract: A reciprocating pump and transmission assembly having a one-way clutch is disclosed. The transmission includes an input shaft with an eccentric element, a drive link rotatably connected at one end to the eccentric element and at the other to a driven arm. The driven arm is connected to a driven shaft via a one-way clutch. The oscillating motion of the eccentric drives the drive link and driven arm and the one-way clutch translates that motion into incremental motion of the driven shaft. By changing the stroke length of the drive link various gear ratios between the drive shaft and driven shaft are achieved. The driven shaft then uses a mechanism such as a Scotch Yoke to create reciprocating motion to drive one or more pumping elements.

Abstract: The disclosure provides a gear pump rotor assembly that includes a rotor body, a rotor head having a plurality of gear teeth and being connected to the rotor body, at least one connector extending between the rotor body and the rotor head, at least one radial deformation control member that extends into at least one gear tooth of the rotor head and reduces the radial deformation of the rotor head relative to the rotor body when a change in temperature causes radial deformation of the rotor body and rotor head.

Abstract: A reciprocating pump having a combination check valve and relief valve is disclosed. The pump includes a pump body having an inlet, an outlet and a pumping chamber. A biasing element provides a force that biases a movable seat toward sealing engagement between a first region of the movable seat and a fixed seat at the inlet. A movable checking element is movable away from a second region of the movable seat when fluid flows in one direction through a passageway in the movable seat. The movable seat also acts as a relief valve wherein the first region of the movable seat disengages the fixed seat if the movable checking element is being forced into engagement with the second region of the movable seat by a force that exceeds the force of the biasing element against a third region of the movable seat.

Abstract: An agricultural harvester includes an auger assembly including an auger having an auger shaft defining an axis of rotation and a flighting carried by the auger shaft, the auger being configured to rotate the flighting in a sweeping path about the axis of rotation; and an auger trough placed adjacent to the auger to hold crop material in the sweeping path and having a bottom below the sweeping path. The auger trough has a first portion on a first side of the bottom and a second portion on a second side opposite the first side of the bottom, with the second portion of the auger trough having an end directed toward the first portion in a direction of the sweeping path.
