Description of the Invention: [Technical Field] The present invention relates to a clearance hole for a reciprocating compressor, and more particularly to: a nut for screwing a piston rod to a clearance piston The two members of the component can be combined to achieve a novel improvement such as stable operation and long-distance operation by screwing without a click. [Prior Art] Conventionally, as one of the methods for controlling the capacity of the reciprocating compressor that has been used all the time, there is a configuration in which a clearance hole is 代表性, and τ is a configuration disclosed in the patent document. That is, in Fig. 3, there is a clearance hole 3, a balancing device 6, and an actuating device (a driving portion of the clearance hole) 8, and a hydraulic means u is used as the actuator: the second balancing device 6 is attached to the clearance hole. The main body 6G is slidably fitted to the balance chamber 61, and the pressure chamber chamber 61 is connected by the communication path 62, and the (4) 1 connecting rod 5 (four) h piston body 7 is coupled to the i-th piston body 4, thereby The air pressure in the pressure chamber is introduced into the balance chamber 61 in the direction of the adjustment chamber. The actuator 8 is configured to increase the volume of the adjustment chamber 31 by the specific position (4). Also: when you want 4 less _ machine capacity ' by opening the gap volume connected to the Cyclone insider / == cylinder 1. In the compressor, the compressor is slammed into the suction stroke, and the compressor is left in the suction stroke. The residual gas in the cylinder of the phantom is the entanglement of the gas, so the sew is until the seam, until the product is 100129157 3 201211392. Until the pressure. If the volume is increased, the volume occupied by the inflation gas during the suction stroke is increased, and the amount of suction is reduced to this extent. In this capacity control mode, the amount of gas compressed by the piston 2 itself is reduced, so that the power consumption can be reduced. Further, as a variable-capacity back-and-forth compressor using a clearance hole, the configuration disclosed in Patent Document 2 can be referred to as FIG. That is, FIG. 4 is a cross-sectional view showing the clearance portion of the main portion of the reciprocating compressor, which is configured as follows: the gap adjusting rod 43 is provided on the partition wall 41 of the cylinder head 41 and has a front end side for closing the cover. The tapered rod portion 43t accommodates the hole 41a of the cylinder 40 of the piston, and is located in the manner of the conical hole-shaped gas passing through the hole (the fourth hole 4u and the head side gas compression chamber of the cylinder 4). The support rod supports the (four) pattern of the mold 44, and the screw rod portion 43s on the proximal end side is screwed to the outer cover 42 of the closed cylinder cover 41, and the gap adjustment rod 43 is connected from the protruding end of the rod support mold 44. The output shaft ' of the stepping motor 45 is moved back and forth in the longitudinal direction by rotating the gap adjusting lever 43 forward and backward. Therefore, the right gap is continuously changed by the remote operation, and the pressure is continuously changed in the suction, so that the amount of gas required in the process is changed at the time of If; This effect is obtained by compressing the amount of gas necessary to obtain a larger amount. Therefore, a device is used which is constructed in such a manner that the actuation can be performed by the operation of the sub-gap eight and the process is performed according to the process conditions such as the ejection force and the measured value is used, for example, via the control device.

The pressure-adjusting piston (retaining piston) of the clearance chamber directly connected to the gas compression chamber of the cylinder acts on the pressure fluctuation corresponding to the suction, compression, and discharge stroke of the gas in the cylinder, so the larger variation The weight is working. Further, for example, in a compressor for oxygen which is highly flammable, it is preferable to use a driving method for avoiding ignition due to high pressure oxygen. Further, in the case of the above-described configuration of FIG. 4, the tapered rod portion at the front end of the screw shaft portion is inserted into the hole-shaped gas passage hole, and the degree of communication with the clearance hole is adjusted by the insertion condition. However, since the gas passage of the flowing person or the outflow hole is narrow, there is a disadvantage that the pressure loss becomes large. Further, although not shown in the figure, the driving by the screw type actuation H is also employed in the manual clearance. In this case, there is a problem that the screw surface is knocked by changing the load, which causes damage. In order to avoid the situation of the '101129157 5 201211392' manual, the following construction points are made, and the other locking nuts are inserted into the 锁定 (4) 纟;: ° The time of the movement of the tamping gamma # avoids the damage of the factory due to the change of the load. However, in order to make two screws == require a complicated mechanism by remote operation, there is a problem in the installation space and cost. Therefore, the object of the present invention is to provide a two-body that is screwed to a screw, which is a card that is engaged via an elasticite member, and can be used to move back and forth between the action of the stable operation and the remote operation (the means to solve the problem). The clearance system of the back and forth actuating compressor of the present invention comprises: a steam red into a suction and a nozzle outlet and a piston is disposed therein; the upper gas retracting chamber and the lower gas compression chamber are connected to the cylinder by the piston And the separation; the cavity body is disposed on the upper portion of the cylinder to read the upper side of the gas chamber and has a chamber and a pocket chamber; the clearance piston in the space cavity; and the driving body The clearance piston is slid, and the volume of the chamber that communicates with the upper body pressure is made variable by the sliding of the clearance piston, and is provided on the outer plug and has an external thread and is prevented by The rod held in the non-rotating state, the nut screwed to the external thread, and the nut of the shape described above are biased in opposite directions via the spring member, and the composition of the second nut portion is further Presented in the above The mother outside circumferential first gear, and is provided in the driving body and the first and!

The second gear' is configured to move the rod and the clearance piston by the driving of the driving body, and the piston back pressure of the clearance piston is used to make the suction and pressure of the steam red The intermediate intermediate pressure acts as a configuration in which the piston back pressure of the clearance piston is used to cause the suction pressure of the cylinder to function, and the spring member is constituted by a disk magazine. (Effect of the Invention) The clearance hole of the reciprocating compressor of the present invention is configured as described above, so that the following effects can be obtained. In other words, the cylinder includes a piston in which a suction port and a discharge port are formed, and the upper side gas (four) chamber and the lower side body H are divided by the piston, and are disposed on the upper portion of the cylinder and The upper side gas waste chamber 2 is connected to each other and has a cavity chamber and a cavity chamber body of the cavity chamber, a clearance piston in the gap chamber, and a drive for sliding the clearance piston, and the clearance is The sliding of the piston causes the clearance of the back and forth actuating compressor with the variable volume of the upper side gas compression chamber = the chamber to be placed on the clearance piston and has an external thread and is screwed by the anti-rotation device The nut of the external thread and the third member that is formed by the spring member and urged in the opposite direction via the spring member, the first two pairs of materials, and the pre-variation, Therefore, even if the sound of the occlusal portion of the screw disappears and acts on the rod, it will not break due to the tapping of the screw surface. 100129157 201211392 Loss and the clearance piston advances and retreats by making the cylinder side The thread is rotated forward and reversed. Further, in the state where the clearance piston is stopped, the spring member a& even if the fluctuation is negative, the screw surface is always urged in the direction and the frictional force is increased, so that the clearance piston does not move arbitrarily. Further, a second gear having η placed on the outer circumference of the nut and a second record disposed on the driving body and engaged with the first wire, and the rod and the clearance piston are driven by the driving of the driving body The movement is performed by using the driving body to rotate the gear to advance and retreat the clearance piston, whereby the _ volume can be changed by remote operation. The capacity adjustment of the compressor can be automatically performed if the input signal is taken in accordance with the human right and the clearance piston is configured to advance and retreat as a necessary amount of gas. Further, the fluctuation load acting on the clearance piston is large in addition to the suction/discharge pressure of the compressor and the weight of the component, and the back pressure acting on the back pressure chamber of the clearance piston is greatly affected. In the case where the average pressure in the cylinder is applied to the pocket back pressure chamber, the inside of the cylinder and the pocket back pressure chamber are connected via a restrictor such as an orifice. However, in this case, the same effect can be obtained by the fact that β is placed in contact with the pores of the back pressure chamber of the front face of the clearance piston, so that the construction becomes simple. On the other hand, since the amplitude of the load acting on the clearance piston largely changes in the vertical direction, it is necessary to increase the elastic force acting between the nuts. In addition, there is a disadvantage that the torque required to rotate the nut is also increased in order to move the clearance piston. In the case where the suction pressure is applied to the back pressure chamber, the amplitude 100129157 201211392 as the load is also equal to the above. However, the weight due to the weight is relatively higher than the pressure load. The weight is small. Therefore, the elastic force acting by the spring member is small, and the torque required to rotate the nut can be reduced.

The above-mentioned nut % is held in the above-mentioned portion, and the P gear is fixed. On the outer circumference of 93 a, the driving body 94 -I is mounted on the above mechanical table 9 through the dense correction 92 . Further, a second gear 96 having a rotational axis % of the driving body 94 formed of a pneumatic motor or the like is engaged with the first gear 93. Therefore, the second gear 96 is configured such that the nut is moved to the fourth (four) switch 94 by the nut, and the clearance piston 58 is moved up and down via the gears 93 and the switching medium 94, and 74 Positive turn. Reverse. Therefore, the port is not called, so that the nut-moving portion 8 of the nut and the nut 74 of the nut 74 can be realized by the upper portion 79 and the driving body 94, and the gears 93, 96, the mechanical table 9, and the branch eight. The operation is described. The drive 94 and the 隹-drive are performed as described above, and the nut runners 94 are stapled via the gears 93 and 96 to form the nut 74. The nut 74 is used to make the nut 74 (four) The females 4 and 76 are biased toward each other by the spring member 77 in the direction of the opposite direction 100129157 11 201211392. Therefore, a load (preload) is applied to the internal thread 73 in advance, so that the air applied to the clearance piston 58 repeatedly overlaps with the above-mentioned preload. In order to rotate the nut %, a relatively large torque is required, but the diameter of the first gear % is η times larger than the diameter of the second gear 96, whereby the nut 74 is easily rotated by the large reduction ratio of the large torque. The clearance of the gas pressure adjusting chamber 31 can be made variable by the high-precision movement of the clearance piston 58 by the rotation of the internal thread without the backlash and the rotation of the internal thread. In the above case, When the clearance piston 58 moves, the volume of the pocket back pressure chamber 51 As a method for avoiding this, as shown in Fig. i, the steam rainbow is connected to the hole f_51 via the ith pressure guiding pipe 55 of the second throttle device 52. Moreover, the pressure in the steam rainbow ι varies between the suction and the discharge pressure accompanying the upper and lower movements of the piston 2, and since the throttle device 52 is provided, the gas generated by the up and down movement is directed to the hole: The pressure chamber 51 has less entry and exit. The result is that the back pressure chamber 51 maintains the average pressure of the suction pressure and the discharge pressure. In this case, for the clearance piston 58, the suction/ejection pressure is in units of i cycles. The difference of 1/2 of the force acts alternately in the positive and negative directions. (The actual applied load-bearing state is slightly changed by the difference in the pressure-receiving area of the cross-section integral of the rod 59 and the weight of the clearance piston 58 or the rod %. Further, as another method, as shown in FIG. 1, the suction port 13a of the suction gas A of the steam red i or the suction valve port 12A and the hole chamber 51 are passed through the second pressure guiding pipe having the second throttle 54 55A connection. The above suction port Ba or 100129157

In this case, the load of the substantially suction/discharge pressure difference acts on the clearance piston 58 intermittently only in the positive direction C.
