Rotating machine

The invention relates to revolving or rotating machines of the type in which the pressure of a gaseous or liquid flowable working medium (hereinafter referred to as "fluid") is varied this type can be, for example, a rotating gas compressor or a rotating vacuum pump, a rotating air motor or a rotating internal combustion engine.

Rotating gas compressors and vacuum pumps that Using liquid pistons are common practice, and internal combustion enginesxi operating on a similar principle are Also proposed in such machines is one with generally radial blades or vanes

909841/1151

Equipped rotor arranged eccentrically within a hollow housing. The housing is filled with a liquid squantum which, when the rotor rotates, drives the housing and forms a ring which is held by centrifugal force on the inner surface of the housing. The effect of the relative eccentricity of the rotor to the liquid ring is that the liquid approaches the part of the rotor between a pair of blades and flies back from it and therefore serves as a liquid piston that compresses the gas in the space between the blades. Appropriate openings or channels through the rotor hub or through the ends of the housing shape the inlet and outlet of the gas to and from the various compartments between the blades. In some cases the housing can also rotate to reduce the friction between it and the liquid ring ₀

The known rotating machines with liquid pistons bring seals and feeding difficulties with them. Their highest compression or expansion ratio is greatly reduced, mainly because the penetration of the radial blades of the rotor into the liquid ring causes a "Coriolis effect", which leads to it causes the ring to break open at high speeds. The use of this type of machine as an internal combustion engine has not proven successful · Apart from

gruitds & tzliohen Hydrodjmaidk- and Verbrisimiaia8 "Pr $ bl" aen one can expect serious constructive difficulties. For example, since the exhaust gases have to circulate along with the rotor, they have to exit the machine at a very high speed, and this would in all likelihood lead to fluid losses from the ring. Difficult balancing and bearing load problems have also occurred

The invention creates a novel rotary Machine * which despite the use of a liquid ring in Completely different way than the conventional machines with liquid rings works and avoiding many of the Difficulties in the way of working and construction, so » like the limitations of conventional machines m $ g » lent.

According to the invention, a rotating machine is created in which the pressure of a working fluid is changed and which has: a hollow rotor housing which is suitable for enclosing a fluid that forms a ring " sen, which forms a ring around a first axis when the machine is in operation; a rotor disposed within the housing and capable of rotating about a second axis parallel to and offset from the first axis; one to move around the circumference of the rotor in a continuous

Preferably the rotor housing is the said one first axis rotatably arranged.

Likewise, preferably said part of the groove is located at one end of the groove the inlet means for the working fluid around one through the an this one end of the groove adjoining ring limited Fluid inlet chamber, and becomes the pocket by surfacing this one end of the groove formed from the ring and for communication with the working fluid in the inlet chamber and made the groove for re-entering that end into the.

Fig. 12 is a longitudinal section of one according to the invention designed internal combustion engine; and

Figure 13 is a cross section taken along line 13-13 in Figure 12.

The rudimentary form of a compressor includes in 1 to 6 show a first rotor in the form of a hollow housing 21 rotatable about an axis 22 a cylindrical peripheral wall 23 and end walls 24,

26 on. End wall 24 has a central air inlet opening

27 and from the end wall 26 extends a tubular Air outlet 28.

An inner rotor 29 is arranged within the genius 21 and an axis 32 is rotatably attached by means of a shaft 22 arranged parallel and offset. The rotor 29 is provided with a wing or a clan 33 'of the respectively viewed * continuous spiral "or extending helically around its circumference so as ^to: form side walls of a spiral or helical groove or groove 34 of the base or she was"

During operation of the compressor see the housing 21 and the rotor 29 both rotate in the same direction, as indicated by the arrows 38,39, and the housing 21 is charged with a liquid maneuvering a liquid ring 37 around its inner circumference forms. Atmospheric air can freely enter the housing 21 through the inlet opening 27, as shown by arrow 41, so that the chamber 42, which is arranged at the left end of the rotor and delimited by the surface 40 of the liquid ring, contains air "Contains atmospheric pressure" The surface 40 of the liquid ring has a radius Rl at the left end of the rotor in relation to the axis 22. Due to the eccentricity of the rotor 29 in relation to the housing 21 there is a radial displacement or displacement of the rotor the flue »own ring 37 in the course of each revolution. This displacement has the effect that the leading end 43 of the rotor rib 33 emerges from the liquid ring once with each revolution and then re-enters the liquid ring,

transforming a quantum of the atmospheric loft into an inner half of the groove 34 formed and closed by the liquid ring pocket is blocked. When turning further of the rotor 29, the air pocket that is enclosed and sealed in the groove by the liquid ring is created along the groove moved further, so that they are as a result of the enlarging Distance of the groove bottom 36 from the rotor axis is pushed radially outwards · The air pocket is therefore through the Fluid is compressed on the smaller volume, which is determined by the decreasing width of the groove · The The air pocket runs through the entire length of the Groove to exit into chamber 44 at the right end of the rotor step, τοπ where they, as shown by arrow 46, through the Outlet 28 is expelled.

At any point in time there is a number of successive ones captured in the groove 34. See air as indicated by the numbers 47,48,49. The distance R2 of the surface 45 of the liquid er inges from the axis 22 at the right end of the rotor is such that aQx hydrostatic pressure on this surface is in equilibrium with the overpressure of the compressed air in the chamber 44 * ie the increase in air pressure caused by the compressor is kept in balance by the increase in the hydrostatic pressure ia liquid ring between the radius Rl and the radius R2

The design <tar closed air pockets and the advancement of these pockets along the groove 34 is illustrated by Figures 3-6. Purely in these Figures is the groove bottom 36 as a continuous screw or spiral and only the leading end 43 of the clan 34 as shown in broken line. The inner Uofanga surface 40 dee liquid hanging 37 at the inlet end of the rotor is shown in FIG. 3 shown. It is appreciated that, as a result of the centrifugal The hydrostatic pressure of the liquid in the ring increases as the distance from the axis 22 increases, i.e. isobars Areas of increasing hydrostatic pressure occur in the form of a series of acidic ring surface 40 consistent cylinders.

Fig. 3 shows the angular position of the housing 21 and the rotor 29, in which the leading end 43 of the rib

33 has emerged from the liquid ring and is about to separate a quantity of atmospheric air from the chamber 42 "before it dips back into the ring to form the pocket 47.

The decreasing groove width is adapted to the increasing radius of the groove, so that the volume of each pocket corresponds to the increasing volume exerted on it by the liquid ring.

It is important to note that even at a high rotational speed of housing 21, liquid ring 37 and rotor 29, the air pockets do not rotate at all, but rather "only run along the rotor with axial and radial Bawetjungskoraponenten. This is best shown in FIGS. 5 to 6 As seen _e mentioned above, isobaric surfaces in the liquid ring inform resulted from the inner periphery of the ring 40 concentric cylinders "Since the compressed air is an elastic medium, no pressure increase is by any of the bags 47,48,49. therefore, it must the outer peripheries of these pockets coincide with the isobar surfaces in the liquid ring and therefore limner on to the
