The side view is for.

First, referring to FIG. 5A, a state in which the piston part is coupled to the cams 220a and 220b is illustrated. The piston portion includes piston rubbers 250a, 250b and 250c, piston bodies 254a, 254b and 254c, piston holders 264a, 264b, 264c, 264d and 264e and piston pins 252b and 252c. Piston bodies 254a, 254b, and 254c corresponding to the respective piston rubbers 250a, 250b and 250c are provided for supporting each of the piston rubbers 250a, 250b and 250c, and corresponding guide pins (not shown). Piston holders 264a to 264e are provided to be inserted therein. The piston bodies 254a, 254b, and 254c and the piston holders 264a to 264e may be integrally formed. Also shown in each of the piston bodies 254a, 254b, and 254c are piston pins 252b and 252c which enable reciprocating movement of the piston along the busbars of the cams 220a and 220b.

The piston rubbers 250a, 250b and 250c have to be kept airtight inside the cylinder portion, for example, so that it may be treated with TEFLON coating. In addition, the material of the piston holders 264a, 264b, 264c, 264d, and 264e may be made of synthetic resin, and the piston pins 252b and 252c may be stainless steel-304 series (SS-304). However, these materials and processing methods are not limited to those illustrated.

Next, referring to FIG. 5B, a state in which each of the piston pins 252a, 252b and 252c is coupled to the corresponding piston bodies 254a, 254b and 254c is shown. The other piston rubber 250d and the piston body (assuming 254d) are covered by the piston 250c and the piston body 254c and are not separately shown. Each of the piston pins 252a and 252b has pin body portions 252a2 and 252b2 fastened to the piston bodies 254a, 254b and 254c and a header portion 252a1 and 252b1 coupled to the bus bar of the cam as shown. . The piston pin 252c may likewise have a pin body portion coupled to the piston body and a header portion coupled to the bus bar of the cam, but not shown. The same is true of the piston pin (assumed to be 252) which is coupled to the piston body assumed to be indicated by reference 254d.

Referring to FIG. 5C together, the operation of the piston unit will be described. First, assuming that the state shown in FIG. 5C is a current state, the position of the piston pin 252a is the highest position, and the position of the piston pin 252b is the lowest. Can be a location. In addition, the positions of the remaining piston pins 252c and 252d may be intermediate positions. If the cam rotates clockwise (when viewed from the top) as the drive motor portion (100 in FIG. 1) rotates in the present state, the piston pins 252a and 252c move downward and the piston pins 252b and 252d. ) Is uplifted.

Looking at the state after the first quarter turn, the piston pin 252a is moved downward and placed at the position of the current piston pin 252c, and the piston pin 252c is positioned at the current piston pin 252b. The piston pin 252b is placed at the current position 252d, and the piston pin 252d is placed at the current position 252a.

After the next quarter turn, i.e. after the half turn in the current state, the piston pin 252a is placed in the position of the current piston pin 252b, and the piston pin 252b is placed in the current piston pin. 252a, the piston pin 252c is placed in the current piston pin 252d, and the piston pin 252d is placed in the current position 252c.

That is, when looking at the center of the piston pin 252a, in accordance with the rotational movement of the cam, the reciprocating motion is repeated to the highest position, the middle position, the lowest position, the intermediate position, and again the highest position. Referring again to FIG. 5B, the piston pin 252a is repeatedly reciprocated to the highest position, the middle position, the lowest position, the intermediate position, and again to the highest position, in further detail, in conjunction with the piston's reciprocating movement. As a result, the corresponding piston rubber 250a also reciprocates in correspondence with the piston pin 252a in the cylinder portion (not shown) formed in the second chamber (300 of FIG. 2). Since the same applies to the remaining piston rubbers 250b to 250d, the repeated description will be omitted. Thus, when each of the piston rubbers 250a to 250d moves from the lowest position to the uppermost position, it may be in the second operation mode, that is, the exhaust mode, and each of the piston rubbers 250a to 250d moves from the highest position to the lowest position. In this case, the first operation mode may be a suction mode.

In FIG. 5B and FIG. 5C, four cylinder modules have been described as an example. However, the above description may be similarly applied to the case where there are fewer than four cylinder modules or more than four cylinder modules. That is, as described above, in the case of four cylinder modules, the first operation mode or the second operation mode is repeated at one quarter of the rotation period of the cam. For example, in the case of three cylinder modules, the cam The first operation mode or the second operation mode is repeated at one third of the rotation period, and when there are five cylinder modules, the first operation mode or the second operation mode is repeated at one fifth of the rotation period of the cam. That is, in general, when the number of cylinder modules is N and the rotation period of the cam is T, the first operation mode or the second operation mode repetition period τ may be represented by the following equation (1).

τ = T / N

The operating states of the intake valves (364a to 364c in FIG. 2) and the exhaust valves 370a to 370c according to the reciprocating motion of the piston unit as described above will be described below in detail with reference to the accompanying drawings.

Since the cam 220, the piston rubbers 250a to 250c, the piston holders 264a to 264f, and the guide pins 260a to 264f have already been described above sufficiently, the description thereof will be omitted.

FIG. 7A is a perspective view illustrating an upper portion of the second chamber of FIG. 2, and FIG. 7B is a schematic bottom view corresponding to FIG. 7A. 7A and 7B, the suction holes 360a to 360c, the suction valves 362a to 362c, the exhaust holes 380a to 380c, and the exhaust valves 370a to 370c are illustrated. Each of the suction holes 360a to 360c and the exhaust holes 380a to 380c may be one or more. Each of the suction holes 360a to 360c may be opened or closed by corresponding suction valves 362a to 362c. That is, each of the suction holes 360a through 360c penetrates into the corresponding inner cylinders 352a through 352c and the outside (see 350a through 350c in FIG. 7A), and is operated by the corresponding suction valves 362a through 362c in operation. It can be open or closed. That is, the suction holes 360a to 360c are open for the inflow of outside air in the first operation mode and are closed in the second operation mode.

Each of the exhaust holes 380a to 380c may be formed in one or more as well. Each of the exhaust holes 380a to 380c may be opened or closed by corresponding exhaust valves 362a to 362c. That is, each of the exhaust holes 380a to 380c has a predetermined space (hereinafter, referred to as a combination of the interior 352a to 352c of the corresponding cylinder part and the second chamber part 300 and the cap part 400 of FIG. 2). Also called a predetermined space provided by the cap portion). That is, 380a to 380c of FIG. 7A communicate with 390a to 390c, respectively. Thus, each of the exhaust holes 380a to 380c may be opened or closed by the corresponding exhaust valves 362a to 362c in operation. That is, the exhaust holes 380a to 380c are closed to maintain the airtightness of a predetermined space provided by the cap part 400 in the first operation mode, and the respective exhaust holes 380a to 380c in the second operation mode. The outside air of the inside 352a-352c of the cylinder part corresponding to 380c is discharged to the predetermined space provided by the said cap part. Thus, since the piston parts of the cylinder module each reciprocate sequentially (as described above), the air is compressed into a predetermined space provided by the cap by the reciprocating motion. Reference numerals 362a and 364a are the same intake valves, and the same reference numerals 362b and 364b and 362c and 364c.
