Definitions
- the invention relates to a compressed air piston engine, in particular for paint spraying devices, Dosing pumps, grease guns and the like, with one in one Piston cylinder by means of compressed air on its two piston surfaces a slide control alternately acted upon and thereby oscillating Movable working piston with a piston rod that is axially in one Cylinder head and / or a cylinder bottom is guided, in which for the Compressed air inflow or outflow into / out of the piston cylinder each have an inlet / outlet is provided, the slide control one in a control cylinder Movable control piston and control openings in the control cylinder are provided, each a supply / discharge or ventilation lines Connect the compressed air to the control cylinder and are influenced by the control piston and the slide control provided in / on the cylinder head or in / on the cylinder bottom and so is that the axes of the control piston and the working piston are approximately perpendicular stand on each other, with the cylinder head and the cylinder bottom each have a switching valve for the compressed air from the
- Such a, usually single-acting, compressed-air piston engine already exists known and can also be designed double-acting without much effort, where an implement is connected to each end of the pneumatic piston engine is.
- the piston cylinder with the cylinder head or Be formed in one piece, but it is more advantageous if both the cylinder head as well as the cylinder bottom of the piston cylinder made separately and the parts assembled afterwards, like that for example in the patent DE 33 42 388 C3, so that the required Machining of the parts can be kept low.
- the slide control is either attached to the side of the piston cylinder and optionally carried out in one piece with it, or it is located as in the arrangement according to DE 33 42 388 C3 above the cylinder head or if necessary also below the cylinder bottom; in these Components, the slide control can be structurally integrated. Both orders are unfavorable.
- the invention has for its object the above Disadvantages of the known compressed air piston motors described of the type specified at the beginning to eliminate and a slide control space-saving and suitable for different working strokes of the working piston to install.
- each of the changeover valves provided with a differential slide is that of a first valve piston of larger and a second Valve piston of smaller piston area, which is at a fixed distance are attached to the valve piston rod.
- the axis of the control piston of the axis of the working piston is spaced because then the piston rod be stored at both ends and / or both through the cylinder head as well as can be passed through the cylinder base without doing so to be hindered by the slide control.
- a preferred embodiment of such a compressed air piston engine consists in that in the valve housing from a branch line air pressure the differential slide in a first end position moves in the valve piston rod partially into the piston cylinder protrudes.
- the differential slide is in constant contact with the upcoming air pressure in a preferred first end position from which he solely under the action of the working piston on its valve piston rod a second end position is movable - against that on the differential piston acting force from air pressure.
- a return spring be completely dispensed with, if only care is taken to ensure that the piston surfaces of the differential piston are continuously exposed to compressed air.
- the switch valve is provided axially parallel to the working piston and in the cylinder head or bottom a circular cylindrical bushing for mounting the differential slide is provided, the implementation against preferably the piston cylinder by means of a elastic closure is blocked by the Valve piston rod is pierced and on which the first Valve piston can be applied under the effect of compressed air which is therefore somewhat cushioned there, so that noise and wear remain low.
- the implementation advantageously has one threaded bush locked with a screw plug in which the second valve piston is guided which is a supply / discharge line leading into the changeover valve shuts off as long as the first valve piston is on the closure rests. This ensures that the differential slide is independent of that in the Incoming / outgoing air pressure in the first end position as long as it is not from the piston is moved out of this.
- Control cylinder closed on the front side by locking pieces is so that it is in the cylinder head / bottom continuous bore can be formed; the locking pieces are best threaded plugs. If on that Control piston preferably elastic stops at the end are provided, which alternately on the closure pieces stop, then the control piston even spared; the elastic design of the stops extends the life of the spool and reduces noise.
- the supply / discharge lines from the changeover valves open into close the locking pieces so that they are off the spool cannot be influenced and this alternately the air pressure of the Compressed air source is exposed.
- control piston occurs when there is a second control chamber on each provided on both sides of the first control chamber and alternately fluidly connected to an associated outlet is.

- FIG. 1 shows the longitudinal section in the region of the cylinder head 2, deviating from the other (axial) section, also been put through a changeover valve 7, that is also provided in the cylinder base 3 in the same way and is drawn enlarged in FIG.
- Both switch valves 7, whose spaced from a major axis HA of the air piston engine Location emerges from Fig. 3,4, are executed essentially the same and in a circular cylindrical, partly smooth and partly threaded Implementation 25,33 of the cylinder head 2 or the cylinder bottom 3 is provided.
- the bushings 25, 33 are on the one hand via an associated one Branch line ZL1.2 connected to a main line HL for the compressed air, which in turn from one omitted in the drawing and only by a directional arrow Q illustrated compressed air source fed with compressed air becomes; the arrangement is such that the compressed air is constantly in the Implementations 25.33 is due.
- the branch line ZL2 bridges outside of the piston cylinder 1 the free space between the cylinder head 2 and the cylinder base 3 with the help of a straight pipe section RS3, which axially parallel to the piston cylinder 1, clamped between the two.
- Both switch valves 7 working as sliders are in turn axially parallel arranged to the piston cylinder 1 and have a differential slide 71, which consists of a first valve piston 71a larger and a second Valve piston 71b of smaller diameter, which is at a distance a firmly attached to each other on a common valve piston rod 71c are and the two alternate end positions in 1.5 are indicated, where the first end position is extended and the second are drawn with dashed lines.
- the bushings are 25.33 from the piston chamber 10 of the piston cylinder 1 by an elastic closure 72 pneumatically separated, that in the cylinder head 2 or the cylinder bottom 3 is fastened and has a guide bore 72a in which the Valve piston rod 71c is axially movable. You can in the piston chamber 10 protrude so that then its free end face 71d is in the working area of the working piston 4.
- the bushings 25, 33 from the surrounding area U are one Locking screw 73 with a central vent hole 73a separated.
- An aligned threaded bushing 74 is located on the screw plug 73 a guide cylinder 74a in which the second, smaller valve piston 71b is easily guided longitudinally.
- One ends in the guide cylinder 74a Inlet / outlet Z1.2 to a slide control located in the cylinder head 2 8.
- the first, larger valve piston 71a is directly on the smooth cylindrical surface of the bushing 25.33.
- Fig.1 is also indicated that the working piston 4 with a piston rod 41 is provided in the cylinder head 2 and the cylinder bottom 3 is mounted centrally and slightly longitudinally. At its (bottom) end an implement can be coupled; for double-acting devices this is possible at both ends.
- piston chamber 10 is located on both sides of the working piston 4 each a combined inlet / outlet 26,34 for the compressed air in the Cylinder head 2 and the cylinder bottom 3.
- the inlets / outlets 26, 34 are by means of Working lines AL1.2 pneumatically connected to the slide control 8, the working line AL2 via a (second) straight pipe section RS2 the free space between the cylinder head 2 and the cylinder bottom 3, clamped between the two, bridged.
- directional arrows R1 (Fig.2) indicate the oscillating exposure of the working piston 4.
- control cylinder 81 In one in the form of a socket in the cylinder head 2 inserted control cylinder 81 is a control piston 82 guided axially easily movable.
- the control cylinder 81 extends transversely to the main axis HA of the Air piston engine and (Fig.1) of this around the dimension e spaced in such a way that the piston rod 41 is not affected in its axial position.
- the supply / discharge lines open in the vicinity of the closure pieces 83 Z1.2 from the changeover valves 7 so that they, not lockable, always have an associated face of the control piston 82 alternately apply compressed air can.
- the working piston 4 and the two valve pistons 71a, 71b each with only one piston ring are equipped on their lateral surfaces in the slide control 8 a total of five against each other areas to be sealed by four located on the control piston 82 and approximately the same Piston rings arranged at axial distances from one another pneumatically in corresponding annular grooves 82a are separated.
- control piston 82 annular control chambers 82b, c recessed, which two adjacent control openings 81a-c with each other flow connections in which the main line HL, the working lines AL1.2 and ventilation lines EL lead; the vent lines EL lead on the other hand indicated in the environment U via the air filter 5 by arrows R2 (Fig.2).
- the differential slide 71 are under the influence of the constant pending via the branch lines ZL1,2 Air pressure from the main line HL so long with your first valve piston 71a on the respective closure 72 at how the associated, overly in the piston chamber 10 projecting valve piston rod 71c not from the working piston 4 is charged.
- undressed drawn end position of the differential slide 71 are the respective feed / discharge lines Z1.2 from the associated ones Branch lines ZL1.2 separated and vented via the vent holes 73a.
- the working piston 4 transports the differential slide 71 into the dashed second end position, then compressed air gets into the supply / discharge lines Z1.2, so that the spool 82 axially into its other End position comes, and the vent holes 73a are cordoned off.
- the supply / discharge lines Z1.2, accordingly in the first end position of the differential slide 71 act as venting discharges, end on both sides of the control piston 82 and cannot be influenced by this in the control cylinder 81 (Fig.3).
- the control piston 82 connects to its first control chamber 82b, as indicated in Figure 3, with the Main line HL related control opening 81a one of the control openings 81b, in which one of the working lines AL1.2 opens.
