Definitions

  • This invention relates to an electrical pump for fluids, eg hot water or for coffee machines, with economical outlay and power consumption.
  • a generally cylindrical armature/piston combination which slides axially and has a generally axial internal bore to pass fluid from an inlet to an outlet, also has one or more radial bores between the axial bore and its exterior inside a sliding guide for the combination.
  • the radial bore serves to prevent fluid build-up between the combination and its guide. Such a build-up has a braking effect on the armature/piston combination due to pressure and viscosity, but is relieved by the prior art radial bore.
  • the bore is expensive to machine and the machining can form a burr (a jagged irregularity projecting from the hole) which tends to scrape and wear out at least the assembly and its guide.
  • burrs of wear the loss of force and power due to peripheral fluid build-up can amount to 50%, and so has typically been dealt with in this way.
  • the invention aims also to minimize the peripheral fluid presence and consequent braking effect, but without causing a burr and/or incurring the expense of radially machining into the axial bore.
  • the armature/piston assembly and/or its guide is shaped to facilitate peripheral fluid mobility.
  • a second aim according to a preference of the invention is to simplify production of the downstream part or end of the combination which has in the past been externally tapered or reduced in diameter by machining, which is quite expensive in time and loss of magnetic material.
  • the invention preferably provides an armature assembly formed by a reduced diameter body which may be of a different, non-magnetic material or metal, crimped to the main body of the assembly.
  • the axial bore must be continuous but can be machined or moulded, cast etc separately before the two pieces are crimped together.
  • the known pump has an inlet port 1 from which fluid is pumped by an axially vibrating armature/piston combination 2 to an outlet port 3, through an axial bore 4 in the entire length of combination 2, an inlet valve 5 and an outlet valve 6 in an axial passage in the housing 7 leading to the outlet port 3.
  • the outlet valve 6 is merely a one-way passive or flow-responsive valve, but the inlet valve 5 is opened by separation of the piston part, ie by the leftward movements of armature/piston 2 in its vibrations.
  • the leftward movements cause fluid to be transferred from inlet port 1 past the inlet valve 5 and thence to the outlet 3.
  • the leftward armature movements are caused by repeated energizations of a solenoid coil 8 via a terminal T and act against a return spring 9.
  • the repeated energizations can result conveniently from half-wave rectified ac, eg at 50 Hz, between the half-waves of which the spring returns the combination rightward to close inlet valve 5.
  • Both valves 5 and 6 are spring closed by return springs 10 and 11, spring 10 being weaker than spring 9.
  • An annular volume 12 is arranged to collect fluid which unavoidably flows between the outside of the armature/piston and its guide 13, but tends to get full enough of fluid to impede the amature vibrations. This tendency can be relieved, as known, by one or more radial bores 14, which provide relief conduits, from volume 12 when undesirably full of collected fluid, to the central bore 4.
  • Such machining as aforesaid is costly and can leave burrs or loose metal particles prejudicial to the action or life of the pump.
  • Another drawback, trapped fluid suffers a time delay before it can even reach volume 12, so it is impeding the vibrations during this time delay, even if fluid does not accumulate unduly in volume 12. The invention seeks to avoid all these possible drawbacks.
  • the invention appreciates that, although a relatively long axial bore has to be provided, the narrow end need not be magnetic or so heavy.
  • the magnetic circuit may comprise outside the coil outer encapsulation 19, a rectangular yoke (not shown) of two L-sectioned pieces crimped together along their corners, a first cylindrical internal part 20 outside the thin armature guide 13, a ring 21 magnetically connecting the yoke and cylinder 20, a second cylindrical internal part 22, and a ring 23 communicating cylinder 22 to the yoke.
  • the L-pieces have respective holes closely surrounding rings 21, 23.
  • the guide 13 has eg. five internal longitudinal ribs 25 (see also Fig.5) on which the sliding armature bears and between which any trapped fluid can readily return (as shown by the flow line arrows 25 ⁇ ) to the pumped stream travelling rightwards through the bore as before.
  • the ribs can be provided without machining and at low cost in the mould of plastic guide 13, and free particles are unlikely and not metallic.
  • the wide part of the armature/piston can have a non-circular cross-section as shown by the four longitudinal flutes of Fig.6 or the extended polygon of Fig.7.
  • the longitudinal irregularities can be strictly parallel to the axis, or can be oblique or helical or otherwise to provide this longitudinal communication, and hence lack of pressure build-up and viscosity drag, while enabling efficient piston effect and hence pumping action.
  • the armature/piston can be in two parts as shown in Figs. 3 and 4, while having the inventive elongated irregularities of Figs.5-7, although the two-part arrangement could be adopted alone.
  • the pressure reducing irregularities are best seen in the transverse cross-sectional views of Figs 5-7, but they are longitudinal in nature, being grooves or ribs or corners either parallel to the axis on having an axially directed component (eg. helical irregularities).
  • a wide part 26 of the armature/piston has a central bore 27 and a holding portion 28, the top of which has an annular groove 29 to surround a lip 30 which can be crimped inwards by a suitable tool (not shown).
  • the section of bore 31 of holding part 28 serves to accommodate a non-magnetic part 32 (eg. of brass or lighter plastics as suitable) shown in Figs 2 and 4.
  • Part 32 has a waist 33 to accommodate in fluid-tight manner an annulus of crimped-in material from lip 30 as can be seen in Fig. 4.
  • the end 34 of part 32 is shaped to serve as a valve seat for inlet valve 5, Fig. 2.
  • the inlet end 35 of wide part 26 may be flared to promote flow and have a circular projection to seat and hold the return spring 9. Any ribs or grooves in the wide part of the armature cannot be seen in Fig.4, and indeed may not be present whenever such flow-conducive shapings are applied to the guide only (as presently preferred, eg see Fig 5) and not to the armature (embodied as by Fig 6 or Fig 7).). Not only is the narrow part provided without necessity to machine down the wide part, but boring only of shorter axial lengths is needed.
