a passageway (17) and an inner housing cutout or crown (16);
In order to allow communication between the inside of 1 (Ill'l,
A circumferentially extending opening 09) is provided in the inner housing sleeve or crown Oe.

The housing 0]) can be connected by a connecting piece (4) to a source of fluid substance, such as an ice cream mix, which fluid source is in communication with an oil hole (21) in the housing αη. , the through hole (g]) is connected to the passage 07) by the opening (a).

If necessary, this connecting piece can be used to introduce ice cream mix or other fluid 1, which allows air to enter the straight hole in the connection 11 and flow through the through hole (2I) leading to the passage 0. A plurality of holes (C) can be provided that are aligned with the air intake hole (C) of 0 υ so that the air can be mixed with porcelain.

Ball (c) supported at the end of the contact piece (a)
The non-return valve has a device ii (c) which prevents the ball from entering the passage aη through the opening (2). This device (a) has a screw rod that penetrates the wall of the maggot/da0]) and reaches into the through hole QI). Additional hole (a)
is provided to connect f:l=kasuinochi, if necessary.

The vane blade has a depth equal to the depth of the recess (ha) at the blade's edge, and extends from the inside of the blade (18) through the opening 0 [phase], (

Well-known sealing devices such as gaskets and QIJ songs are used as necessary to prevent ice cream mix or other fluid material delivered by the pump from escaping anywhere other than the exit orifice. .

When using the rotary displacement pump 00 described above, the ice cream mix or other fluid is passed through the passage C1η and the internal nozzle knob or crown (1 (9
If the internal θ barrel is filled to capacity, the shaft drive is activated.

Then, the disc θ4) is rotated clockwise, and the vane and the blade can be moved in the same direction by the internal nozzle knob Q (9) to direct the fluid material in front of the blade to the passage 0. This movement of the vane (or) blade compresses the fluid in the decreasing volume portion of the passageway (07) until a pressure exceeds the fluid pressure JJ in the internal tube. At this point, the fluid being compressed by the blades or vanes (c) enters the interior of the internal nozzle knob or crown 0υ,
At that time...the fluid inside the maggot knob is pushed out of the housing through the orifice ■, and the vane or blade (c).

It is stopped by controlling the drive by means of known devices.

During the above-mentioned movement of the vane/blade, i.e. while the vane passes the stop in the opening hole (A), the ice cream or other fluid substance enters the opening (a) into the opening (a). 1, filling the space behind the vanes and blades until the vanes or blades are in the position indicated by the dashed line in FIG.

When the pump needs to be cleaned, the cover is removed by removing the hinged stand 0υ, leaving the blade vanes and the inside of the hose easily accessible.

It will be appreciated that the passage α force and the volume of the internal housing or crown αO can be selected depending on the amount of fluid substance to be expelled with each revolution of the pump.

Referring now to Figure 4 and Figure 5, (110) indicates a pump, the housing (11,2) of which
As shown, the cross section is generally circular. Circular mouth!
')'t (114) is formed in the housing (1, 12) and is identical to zo J], but the second circular recess (116) is formed in the housing (1, 12), while the second circular recess (116) is .4) is centrally formed within the housing (110) at its inner end.

The middle hole L of the concave groove i (116) is the circular concave hole (114
) and (116) by a distance equal to half the difference in diameter from the center of the recess (114), so at point (119), the circumference of gate r91 (114) is , coincides with the circumference of the recess (116).

The disk (11,8) (rJ, has a thickness not greater than and preferably equal to the depth of the recess (11,6) and
16) It is mounted in a rotary position inside...Ujinobu (11)
2) is connected in driving relation to a shaft (120) passing through it.

jINI+ (120) (is connected to a drive device (not shown).

The outer end of the recess (11, 4) is covered with a removable cover (12).
4) xj is stopped.

The annular rotor (122) is mounted on the disc Qtg).

a depth at least equal to the depth of the recess (1, 14), preferably a disk (118) and an inner surface of a removable cover (124) sealing the outer end of the recess (114); It has a depth that extends between

Thus, a fluid flow passage (126) is formed between the outer circumference of the rotor (122), the circumference of the recess (114), the bottom +/a of the recess (114) and the inner surface of the removable cover (124). It will be seen that it is defined between And this fluid flow path (
126) is located upstream of point (119) for fluid flow through this passageway (1,25'I).
) and the fluid flow through passageway (126) at point (
It communicates with the output (130) located downstream of (119).

As can be seen in Figure 4, the fluid flow passageway (126) gradually increases in area as it progresses towards the outlet area (131) where it communicates with the outlet (130). The removable cover (1, 24) has a plug (1, 24) located in the middle.
32), which supports three blades or wipers (134), which project radially from the plug body (132). Each blade extends through an axially extending slot (122a) formed in the rotor (122) and is equally spaced circumferentially.

Each blade is engaged by a sealing system (1:36) mounted on the rotor (122) to restrict and preferably prevent fluid from entering the middle portion of the rotor (122). is being prevented.

The blades have a width equal to the width of the first recess (114) and, as can be seen in FIG. As the blade rotates through the fluid flow passageway (126),
recess (114) for a distance of at least 120° or for a distance of sufficient length to allow a trailing blade to reach a point (121) downstream of population (128);
will be in contact with the circumference of

Each blade is freely rotatable relative to the plug (132), so that when the rotor rotates counterclockwise, as shown in FIG.
) will rotate around.

A filter, not shown, is placed within the ILI (128) to ensure that particles larger than the minimum radial gap between the rotor (122) and the circumference of the recess (114) do not enter the flow path. Make it.

When the rotary positive displacement pump (11) is to be used, the fluid flow passage (126) is completely filled with fluid substance and the drive shaft (120) is activated. When (118) is turned in the counterclockwise direction,
The rotor (122) and thus the blades (134,) rotate in the same direction to move fluid material through the fluid flow passageway (1, 26). Movement of a blade (134) in contact with the circumference of the recess (114) forces fluid downstream of the blade toward the outlet (130).

Rotation of the blades (1, 34) below point (121) creates a pressure drop over the vane area so that fluid leaks east from the inlet (12B) and is forced out by the blades of jc. fluid is replaced.

Although the pump described above can be rotated continuously so as to continuously expel fluid from the outlet (130), it can also be used to extract a predetermined amount of fluid. This is achieved by determining one-third of the rotor rotation, and the pump is moved so that the tip of one blade (134) is in the recess (114) at point (1Z).
) in contact with the circumference of the play 1 and its adjacent downstream brain (134) will discharge an amount of fluid equal to the fluid contained between it.

By virtue of the fact that the rotor (122) is radially spaced from the circumference of the recess (114,) over the entire circumference except for one point (119), and by the presence of the population (128) i/co filter, The particles entering the fluid flow path are transported to the rotor (12
2) and the circumference of the recess (1,1/I) to be forced out to the outlet (11); it will be seen.

Further, the tip of the blade (134) is located in the recess (1, 14).
It will be appreciated that since the blades are not in contact over their entire circumference, wear and tear on the blades will be reduced and the life of the pump will therefore be extended.

In the embodiment described above, although the rotor (1 [il and (122)) is actively rotated to rotate blades (08) and (134), respectively, the structure of the pump is (134) is mounted on the driven shaft, and the associated rotors are respectively recessed (lla
) and (114) may also be freely rotatable.

Thus, as the driven shaft supporting the blades rotates, the rotor will be rotated by those blades.

Although this pump can be made of either metal or plastic, if it is to be used for substances intended for human consumption, metal or plastic may prove suitable for such applications. Probably.

Also, although this pump described a fluid with such a viscosity that it will not flow unless the pump is activated, the pump also has a fluid that flows freely even if the pump is not activated. It is also possible to provide a device that can be used for Such devices are well known to those skilled in the art.

Although specific embodiments of the invention have been described, the invention is not limited thereto. For example, the cover may be integral with the housing, or the housing may be made of two parts joined together.
