Device for pumping or compressing

The invention relates to a device for pumping or compressing, which is also operated as a motor can be, i.e. on facilities that are designed to transfer a medium from a Singangsleitung to a Output line to pass over after one if necessary has changed the pressure or to carry out such a conveyance in order to generate a torque on a shaft.

From the French Patent 1,494-95I discloses a pump which which consists of the following parts:

a solid housing with a wall that is bounded on the inside by a surface designed like a ball crane and that inside this wall a conical shape Has a singing surface that is centered in the center of the Eugelkranzes and lies on the same axis as this one,

Means to prevent au each part rotates around its axis, and a bellows that has a support ring of the Housing and a support ring of the moving part tightly connected, which is preferably inside the inner ball ring is arranged.

The invention is based on the object of the KLätübedarf a to reduce such a device with several stages, in which the pumped (or compressed) medium (or the motor) remains completely isolated from the roller bearings and other parts exposed to lubrication and the atmosphere are.

The invention is based on a device of the above type and consists in that they have cylinders with axes parallel to the axis of the EDabe, which are in the section of the fixed housing are arranged, which with respect to the movable part on the opposite side of the section with the truncated cone

granular surface, pistons that move in the cylinders can and contains rods which connect the pistons to the moving part "and that means are provided connecting the output (or input) of the first stage to at least one of the cylinders.

The invention also provides that the connection between the piston rods and the movable part and / or the piston rods and the piston, preferably by means of ball joints which are protected by sealing bellows, which are preferably metallic bellows at their ends on the piston rod, the moving part and / or the piston are welded on.

An exemplary embodiment of the invention is shown in the drawing. Show it:

1 shows a longitudinal section through a compressor along the line I - I of Pig. 2,

FIG. 2 shows a cross section along the line II-II of FIG. 1 and FIG

5 and 4 parts of the device in an enlarged view.

The first stage of the compressor corresponds to that of the pump according to the above-mentioned franz. Patent; it "consists of a housing 1 in which the medium to be" compressed is over a line 2 is led to and via a line 3, where the conveyance takes place by means of a movable part 4-, which is connected to a drive shaft 5.

^ The housing consists of a wall that is connected to the inside by a

spherical surface 7 is limited with the center 0 and the axis AB and which extends symmetrically on both sides of a diametrical plane, as well as a part arranged within the flax 7 with a surface 9 lying on a truncated cone with the axis AB and pointing to point 0 is centered. ^;

In the housing 1 is a hub 10 which is fixed to the shaft 5: is bound, fixed by means of roller bearings 11 so that it can rotate about its axis which coincides with the axis AB

The movable part 4- consists of a sleeve 4 ^, which means Roller bearings 12 on a kinked extension 10 ^ of the property 10 is attached. And rotates around the axis CD :, can that runs inclined to the axis AB and intersects this 5m point 0, a frustoconical surface I3 with an axis CD which is centered on the point 0 and along the nit dor surface 9 a section s can come into contact as well as one outside

Wall delimited by a surface 15 in the form of a spherical section centered at, O, with the axis CD _1, which can move closely with respect to the inner band of the surface 9.

In addition, it is generally advisable to avoid any contact between the pumped medium and the connecting elements to prevent, especially if these consist of parts that may be inserted during the relative movement a lubricant cooperate.

In a preferred embodiment of the invention, each rod 35 is rigid with the corresponding piston 3S and by means of

a ball joint connected to part 4. For this purpose, the ends of the rods on the side of the part 4 are provided with a ball 36 (Pig «4) enclosed in a seat 46 which is integral with the part 4, the ball-frame arrangement itself through a sealing bellows 39 is protected, the two ends of which can be welded directly onto the rod and the part 4. It is carried out lubrication of the ball joint by introducing lubricant into the seat 46. In a deraritigen embodiment, it is sufficient uia the slight vibrations of the piston 36 (and the rod 35 which is attached thereto), vanrend the wobble of the portion 4 to allow ₅ only between the piston and the cylinder 37, in which it slides, to provide a sealing element of small axial dimension, which element also forms a kind of bearing for the oscillatory movements.

A roller connection could also be provided at the ends of the rods.

The two bellows 20 and 39 are only subject to slight conical bending stresses of the type that in relation to one of the end faces which are regarded as fixed, that is, the other end face only bends corresponding to a conical rotational movement of its axis uia the axis of the fixed surface below

i these the housing 1 contains five cylinders 37, which are regularly distributed around the "./eile 5" »Das compressed gas that at 3 from the first stage exits (3? ig. 3), becomes (compare the arrows 4ü Figures 1 and 2) in two of the cylinders 37 over

third single cylinder of the same diameter ejected like the two preceding ones and from there gradually into its fourth cylinder with it smaller diameter (see refs. 4-3) and a fifth cylinder with an even smaller one Diameter (forget the arrows 4-4-) printed by where it is heavily compressed at 4-5 v / ird.
