gerotor pump having annulus and rotor meshed together and located in a body comprises pressing a cover plate (Fig.1) or equivalent as an interference fit into the body and then allowing it to relax and recover elastically to set up the required tolerances at axial ends of the gerotor set....
A gerotor pump comprises the usual lobed annulus 30 containing the lobed rotor (not shown in Figure 2) which is journalled on cylindrical boss 36. The boss is free to turn on the eccentric pin 38 between positions controlled by limit pin 42 encountering end abutments. This enables the pump...
A gerotor pump can have a particularly short axial length by fixing the main shaft in the body (instead of journalling it in the body) and journalling the rotor on the shaft (instead of making the rotor fast with the shaft). Figure 3 shows an arrangement in which gear 24 transmits ...
A gerotor pump, Figure 1, has the usual male lobed rotor 16 with n lobes meshed in the female lobed annulus 12 with n + 1 lobes, the two being both but relatively rotatable on parallel axes 14,18. The improvement consists of making the lobes helically extending which smooths pressure ...
A gerotor set (Figure 1) has grooves 108 extending across the end face of the annulus adjacent the outlet port so as to allow flow from each chamber in turn into the outlet at a time when the chamber per se is not yet registered with the outlet, so as to prevent noise due to the ...
Such pumps or motors require a commutator having a circular array of alternating inlet and outlet openings adjacent to a rotating valve plate which regulates flow to the gerotor gears. The commutator of the present invention has a chambers section and a fluid pathways section. The chambers section...
