CONSTITUTION:With a main shaft 17 rotated, a moving spiral body 601 revolves about the shaft on its axis at a distance between the mainshaft 17 and a crank pin 23, and simultaneously, the center point of a pin 608 of an arm 607 of the moving spiral body 601 performs a linear reciprocating movement through the linear reciprocating movement, within a cylinder member 610, of a piston 609 engaging with the cylinder member 610 secured integrally with a cylinder plate 13 of a housing 10. This eliminates a non-rolling revolving mechanism, reduces the number of constituting parts, eliminates the need to keep a gap between sliding parts with high precision, and enables reduction in a manufacturing cost.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in rotary fluid machines, such as compressors, pumps, exhaust cylinders, and the like.

A conventional compressor is shown in Figure 1.2.3. Nidosu.

The operating principle of this compressor (scroll type compressor) is explained with reference to Fig. 1. In this compressor, the two thinly wound bodies (1) and (2) of the same shape, the blade (2) of which is approximately a middle shaft. Discharge port (4

52) and (51′) 5. The suction body (2) is kept stationary, and the other susu-wound body (1) is mounted on a crank rock having a crank radius ρ.

One of the five-wound bodies (2) is revolved around the center O at a radius ρ=00' (see arrow) without rotating. At that time, between the two squirrel-wound bodies m(2), there is a point (51X52) where both abut, and a point (51,',) (52').
A closed chamber (3) (3) is formed at the end of the closed chamber (3) (3), and the volume of the closed chamber (3) (3) gradually changes during the revolution VC1 of the thin winding (tl). That is, if the squirrel-wound body (1) is rotated 900 times from the state shown in Fig. 1 (1), it will be in the state shown in Fig. 1 (11), and if it is rotated 180 degrees,
x When it reaches the state shown in Figure CI) and revolves 270°,
The state shown in FIG. 1 (1v) is reached, and during this time the volume of the small chamber (3) gradually decreases.

In the state shown in Fig. 1 (IV), the two small chambers (3) (3) communicate with each other to form a sealed small room (53), and the state shown in Fig. 1 (1v)

Thereafter, the above action is repeated to compress the gas taken in from the outer space of the five-spool body and discharge it from the discharge port (4).

The above is the operating principle of a scroll compressor,

) is a movable thrust plate installed integrally on a rectangular tube member (271), and (21) is a plate, a wing, and (2) thrust bearings that receive thrust force from each of five or more members.

In the scroll type compressor, the non-rotating rotating mechanism is of the so-called Scotch Yoke system, and as can be seen from FIGS. 2 and 6, there are (■) a large number of component parts.

(I[) Also, if sufficient accuracy of the gap cannot be obtained,
It is necessary to maintain the clearance between the sliding parts with high accuracy because it causes rattling between the sliding parts and makes abnormal noise, and also causes abnormal pf# wear on the sliding parts, which significantly shortens the life of the machine. This results in higher costs.

The present invention addresses the above-mentioned problems, and includes a pair of thinly wound bodies that are relatively shifted and overlapped by degrees Celsius so as to form a contact point, and each of which is fixed to a separate end plate; means for rotating the thinly wound body relative to the other thinly wound body; It relates to a rotary fluid machine characterized by having a means for moving the machine in a linear reciprocating motion. A) Point G provides an improved rotary 6111 body 4;-y machine that eliminates the need for a Scotch yoke rear side and eliminates the conventional drawbacks.

Next, the rotary bIL body machine of the present invention will be explained with reference to an embodiment shown in Figs. 4.5.6.

An arm (607) provided integrally on the piston (43) is connected to a piston (609) via a one-rotation pin (608). The piston (609) is fitted into the housing (cylinder plate of l) (cylinder member (α) 1 integrally fixed to +31), and the piston (609) and cylinder member (610) reciprocate in a straight line. Try to exercise. Incidentally, the revolving movement of the movable thinly wound body (6r+1) is performed by exactly the same means as in the conventional one.

The rotary fluid machine of the present invention is configured as described above,

As described above, in the present invention, instead of the non-rotating rotating mechanism, one thinly wound body is connected to the other spiral body.
One of the thinly wound bodies is moved 5e so that one point of the same thinly wound body moves in a straight line reciprocating direction M5 with respect to the other thinly wound body. It uses a rotating means (f309x610), eliminates the need for a non-rotating turning mechanism, and eliminates the drawbacks of the conventional model. That is, the number of component parts is small (Z), and there is no need to maintain the precision of the gaps between the sliding parts (therefore, there is an effect of reducing costs).

For example, in the embodiment described above, the locus of the linear reciprocating motion of one of the thinly wound bodies passes through the center of the other thinly wound body, but the locus does not necessarily have to pass through the center of the other five-threaded body. In other words, it is sufficient to fix one of the two five-spool bodies, let the other revolve, and make a part of it move in a reciprocating linear motion in a certain direction. Further, the thinly wound shape of the thinly wound body may be any shape as long as the two five-shaped spirally wound bodies have a plurality of contact points as explained in the section 1 of the principle of operation. Further, a sliding member may be used in place of the piston (609), which is a mechanism for generating linear reciprocating motion, and a guy F member may be used in place of the cylinder member (6]0). Furthermore, the rotary fluid machine is not limited to a compressor (the present invention can also be applied to rotary fluid machines such as a 1-dump, an exno-dia, etc.).
