Definitions

  • a reciprocating electrom-agneticallydriven plunger pump comprised of interfitting U-shaped members forming a housing for pump elements. At least one of the U- shaped members is a substantial structural member and a good magnetic flux conductor.
  • Inlet and outlet fittings are removable plugs or nut-like members retained in opp site legs of the structural U-shaped housing member and retain between them pump sleeve and movable elements such as plunger and valves as a cartridge-like assembly. Electrical components, for example coil, are retained concentrically piloted by one of the fittings and retained laterally by a U-shaped member.
  • the pump of the present invention consists of a basic reorganization of pump structure to achieve a pump functionally equivalent, but at much lower cost and more readily serviceable compared to known pump types.
  • FIGURE 1 is a cross-sectional view of a preferred embodiment of my pump
  • FIGURE 2 is a plan view of the pump viewing the right side of the pump as oriented in FIGURE 1;
  • FIGURE 3 is a top view of the pump rotated 90 from the orientation illustrated in FIGURE 1.
  • my pump is comprised of two interfitting U-shaped housing members and 12 which form the six sides of a volumetric space for locating basic pump mechanical and electrical parts.
  • Housing member 12 has bent-over tabs 14, 16, 18 and 20 laterally forming a connection with legs 22 and 24 of housing member 10.
  • Housing member 10 is fabricated from magnetic fluxconducting material such as iron, steel or the like and the metal stock is relatively thick, providing a. rigid structural housing member.
  • a pair of aligned holes, 26 and 28, preferably threaded, are formed in legs 22 and 24 respectively of housing member 10.
  • An inlet fitting 30 in the form of a hexagonal plug or nut-like member is threaded into hole 28.
  • An internal passage formed in fitting 30 has varying diameter portions which functionally comprise: inlet passage 32; inlet check valve seat 34; seating wall 36 for inlet check valve retainer; and inlet retaining bore 38 of large diameter for receiving the plunger and sleeve cartridge.
  • outlet fitting 40 also in the form of a plug or hexagonal nut-like member, is threaded into aligned opening 26 in leg 22.
  • An internal passage in fitting 40 forms an outlet passage 42 and an outlet retaining bore 44 of diameter equal and aligned to bore 38 for receiving plunger and sleeve cartridge.
  • Outlet fitting 40 has a cylindrical extension 46 projecting 'ice into the housing.
  • Thin sleeve member 48 fits at opposite ends into bores 38 and 42 forming a sliding guide for piston or plunger 50.
  • Sleeve member 48 is fabricated from brass or other flux non-conducting material.
  • Extension 46 of the outlet fitting extends into the housing sufiiciently to provide significant axial overlap with piston 50 for all pumping positions of the piston to insure adequate surface for the transfer of flux from projection 46, through sleeve 48 to plunger 50 (see arrows indicating flux transfer path in FIGURE 1).
  • Projection 46 also provides a retaining bore internally for sleeve 48 as mentioned, and its external surface provides a locating surface for the annular plastic coil bobbin 52.
  • a through-passage 54 is formed in piston 50 and has a frusto-conical section 56 forming a seat for outlet check valve 58.
  • Valve 58 is loose-fitting and guided by projecting spider 60 and prevented from falling loose by cross pin 62.
  • a shoulder 64 is formed by throughbore 54 and forms a retaining ledge for spring 66 which, on its lower end, abuts against inlet check valve retainer 68, holding it in position against seating wall'36.
  • Retainer 68 guides stem 70 of inlet check valve 72.
  • Inlet check valve spring 74 is captured between retainer 68 and check valve 72.
  • An electromagnetic power coil is disposed in bobbin 52.
  • a number of different and known solid state circuits or interrupter arrangements may be used to obtain periodic energization of coil 80 and basically do not form a part of the present invention.
  • Copending application Ser. No. 565,004 describes a solid state block oscillator circuit of the type that may be used which includes a signal detection coil which may also be wound on bobbin 52 as indicated by coil 82.
  • the legs 22 and 24 of housing member 10 extend to the right of the coil forming a space 84 for housing electrical switching circuit components.
  • Housing 12 has access openings 86 for circuit leads which permit mounting exteriorly heat radiating components such as the transistor 88, FIGURES 2 and 3.
  • Plastic bobbin 52 has a tap portion 90 which extends through a slot, not shown, in leg 22. Power-terminal 92 is inserted through tab portion 90 which provides electrical insulation providing a convenient connection to electromagnetic coil and/or control circuit.
  • the pump operates in a known manner.
  • Energization of coil 80 produces flux as indicated by the arrows which tends to shorten the working air gap A by drawing picton 50 downwardly and simultaneously compressing spring 66.
  • Downward motion opens check valve 58 and closes check valve 72, causing fluid to flow to the top side of piston 50.
  • spring 66 will release its stored energy, pushing piston 50 upwardly for a pumping stroke. Upward motion of piston 50 also sucks a new fluid charge past inlet check valve 72.
  • housing member 10 forms the backbone or major pump structural element. Additionally, it comprises the lateral pole pieces for coil 80, normally provided by separately fabricated pieces, as well as circumferential flux path. Legs 22 and '24 are extended to provide space 84 within the pump housing for control circuit elements. Lastly, housing member 10 is the mounting block for inlet and outlet fittings.
  • Housing member 12 completes the enclosure, provides a mounting surface for heat radiating electrical components and a pump mounting bracket.
  • An electromagnetic plunger pump comprising:
  • first and second U-shaped housing members each having a pair of interfitting leg members forming opposite housing Walls and defining an internal pump chamber
  • a fluid pumping piston member of magnetic material disposed in said sleeve member and reciprocable therein; spring means bias said piston member in one direction; an electromagnetic coil member concentrically arranged about said sleeve member and within the internal pump chamber formed by said U-shaped housing members;
  • said electromagnetic coil operative when energized to Y 4 v produce flux moving said piston against its spring bias; and one-way check valve means associated with said piston member permitting fluid to flow through said piston in one direction of movement and to block fluid flow through said piston in the other direction of movement.
  • At least one of said first and second U-shaped housing members is made from magnetic flux conducting material forming a flux conducting pole piece circumferentially and on both lateral side of said electromagnetic coil member.
