GUSTAV SGHNGUT, OF VIENNA, AUSTRIA I PUMP FOR LIQUIDS Application filed July 26, 1929, Serial No. 381,282, and in Austria Iu1y27, 1928. i

This invention relates to improvements in pumps for liquids and the like, of the kind in which electro-magnetic force is brought to bear directly on the pump-piston itself.

U. in previous embodiments of this principle the pump-piston is so constructed as to represent the armature of a magnet, and this armature at the same time operates the cut out'control. Since the armature (serving as 1 piston) must necessarily be packed to prevent leakage, the reater part of the energy applied is waste in overcoming friction. And the fact that the cut-out control is operated by the piston itself implies complicated and sensitive mechanism.

A. further known type of pump made in accordance withthis principle is one in which the armature and the piston, through separate and distinct elements in the construction, are

coupled together by means of a spring. The disadvantage of this type of construction is that it does not sufiiciently exploit the magnetic force employed.

The object of the present invention is to provide a pump with direct electro-magnetic piston-drive which is simpler and cheaper. to construct than the types hitherto produced and which avoids the disadvantages of the latter. According to the invention the pumppiston is perfectly independent of the armature of the magnet and is driven by the blows resulting from the to-and-fro motion of the armature. To this end the armature is provided with a certain interval of free play at.

the beginning of each stroke, during which it is given time to gather impetus which is then transmitted to the piston at the moment of striking. i

i The armature is movably mounted either in the coils of a solenoid or between two horseshoe magnets. The interruption of the cur rent for the coils 'of'the solenoid or for the windin s of the horse-shoe magnets is effected y an interrupter or reversing device.

5 which is separate from and has no mechanical connection whatever with the pump itself.

1 The interrupter used may be one of any of the known types, such as the mechanical,

i electrolytic, or discharge-tube rectifier type. The separation of the controlling mechanism in a socket t.

from the pump itself enables the latter to be inserted in the liquid to be pumped,-a consideration of great practical value.

The drawings illustrate in vertical section in Figs. 1 and 2 two examples of pumps made in accordance with the invention.

In the embodiment illustrated in Fig. 1 two solenoid coils b, 0 are mounted on a tubular holder (1. The middle pieces 0 of this holder consist of magnetically non-conductive material. The coils b 0 are enclosed in a li uidtight casing m. Within the tubular hol er a the armature d is so fitted as to be freely movable to and fro in a vertical sense. The stroke of the armature d is limited by a pin p in the'holder a which projects into a groove 1" of the armature d. The lower end of the tubular holder a forms the suction piece n of the pump, and is provided with the suction valve 1.

The pump-piston i is provided with an extension piece as, which pro'ects through a bore f in the armature d and is itself provided with an axial bore j. The upper end of the mem her a: is fitted with the pressure valve g, above which a nonreturn valve 71. can also be provided. The nozzle 0 serves for the connec tion of the pressure pipe. The pump-piston i, or its extension piece ais provided with a stop-rings, which allows of a certain play of the-armature d to and fro When" the coil 0 is switched in s (in the osition shown in Fig. 1) the armature d will he drawn downwards, first travellin free for a distance determined by the lengtg of the socket t, whereupon the stop-ring s strikes the end of the socket t, so that the member a: and the pump-piston i are operated by .the.blow. The procedure is the same when the coil 6; is switched in, and the armature travels upwards.

{The form of construction illustrated in Fig. 2 differs from that of Fig. 1 only in that twohorse-shoe magnets 'v, v, serve to drive the armature. ,The armature d, is fitted in the ordinary manner between the two horseshoe magnets o, 0 and combined with the tubular tappet d.

What I claim is:

- 1. A liquid pump including an electro- 10c magnet and an armature actuated thereby, a pump piston actuated by said armature, and means permitting limited movement of the armature relative to the piston.

2.A liquid pump including an electromagnet and an armature actuated thereby, a pump piston actuated by said armature, and means permitting limited movement of the armature relative to the iston whereby the range of movement of t e armature is greater than the piston.

3. A liquid pump including an electromagnet and an armature actuated thereby, a pump piston actuated by said armature, and means permitting limited movement of the armature relative to the piston whereby the range of movement of the armature is greater than the piston, and upon reversal of movement of the armature a blow is delivered on the pump piston.

4. A liquid pump including an electromagnet and an armature actuated thereby, a

valved pump piston actuated by said armature, and means permitting limited movement of the armature relative to the piston.

5. A liquid pump including an electromagnet having an axial bore, a pump piston movable in said bore, said magnet including an armature actuating the piston, and means permitting limited movement of the armature relative to the piston.

6. A liquid pump including an electromagnet having an axial bore, a pump piston movable in said bore, said magnet including an armature actuating the piston, and means permittin limited movement of the armature relative to'the piston, said piston and armature being arranged telescopically one within the other.

7. A liquid pump including an electro-magnet having an axial bore, a pump piston movable in said bore, said magnet including an armature actuating the piston, and means permitting limited movement of the armature relative to the piston, said armature extending externall of said bore.

In testimony w ereof I aflix my signature.
