Abstract

PURPOSE:To exactly and synchronously move a piston and a plunger according to the supply of a pressure fluid by a method in which a transmission liquid is confined in the transmission space of a cylinder, and a working pressure fluid is supplied through an entrance into the cylinder. CONSTITUTION:A transmission liquid is confined in a transmission space 26, and the projected end of the rod 20 of a piston 6 is fixed to a structure 36. Under the condition, when a working pressure fluid is supplied through an entrance 16 into a cylinder 4, the cylinder 4 is moved toward the direction of arrow 40, and a plunger 8 is moved toward the direction of arrow 42 by the action of the transmission liquid in the transmission space 26. The volume of the space 26 can thus be kept constant all the time. The movements of the cylinder 4 and the plunger 8 can also be exactly and uniformly performed synchronously according to the supply of the pressure fluid in spite of loads to be connected to each.

Description

[Detailed description of the invention]

The present invention is a reciprocating system that converts the power of a working pressure fluid, such as pressure oil or compressed air, into mechanical linear reciprocating motion. ? I] Urinary Fluid Pressure Actuator More specifically, the present invention relates to the reciprocating type fluid pressure actuator having two output ends that reciprocate linearly. Furthermore, the present invention relates to a quick coupler for removably connecting a row cutting device to an earthmoving vehicle equipped with a 1J7 tow arm and a tilt link, using a reciprocating hydraulic actuator. Conventionally, a forward a + t with two output ends that reciprocate in a straight line.
The I-type fluid pressure actuator has separate electrically operated pistons disposed within a single cylinder, and the rod portion of one piston is inserted from one end wall of the above-mentioned noritsu to 11
! ! The rod part of one piston is protruded from the other wall of the piston 7, and the rod part of the 21-piece piston 7 is used as the output end. The actuator of the expression is a combination of 2 pieces.
11. Mizuki 4 Teta Tatakatashakayag together, Tenten's Nori/Rikara-
A type of actuator is used in which the actuators are pulled out in opposite directions and the rod part of the valley actuator is the output end. However, the actuators of such companies have some shortcomings. First, in the known actuators, those skilled in the art
If the magnitude of the load or resistance connected to the two output terminals is completely the same as in t@Hani (actually, in such a case, they are all close to each other), the two output terminals will be] 514 and evenly, but the page that is in contact with the two output terminals (jr or there is a difference in the size of the resistance' → sum+C+ri
When the negative 1 office to 41 yuan of the 2 fixed units are compared, the output terminal φ of the smaller one becomes hyperactive, so the output terminal of the 21 direction is the same as the other one Vko1ji - ν. '', and without being forced to do so, the master of negative 1 inch can be hit unevenly without cutting 10 J with the size of the circle VC. Therefore, the known actuator can be used in cases where it is required to move the 21 retainers substantially synchronously and uniformly regardless of the respective loads or the size of the grinding head.
cannot be used. 42, in the known actuator, the travel and assist process length of each of the two output ends is set to half the effective length of the gutter/gluer part. That is, in the above-mentioned double piston type, the output is 4'c, and each of the rod parts of the 21st piston is retracted by 4.2mm, and the 2II's thrust is sunk. This is half of the effective length of the welder/da.For the above single rod type actuator, the total length is 21 mm, and for the double rod type actuator, the output end is:
, 7 hl, the length of the displacement V of the rod part of each histograph, and the displacement length of the cylinder that delays the piston by υ4, so the two actuators have l"1 dimension G.
) The lifting platform, the length of the 9th supporting process of the rod part of the piston, and the end of the piston/l111I were all combined into one piece. Measure half the length. Therefore, in the known actuator, the length of each of the two output ends is limited to half the effective length of the output end, and therefore The length of the actuator's nodding section in the +Ill direction must be 2 or more times the length of the output end of the output end, and the actuator's dimensions and load should be・The dimension in the curve direction increases. Of course, Siri 7 + 'A k so-called telescopic (nested)
It is possible to increase the length of the output end by increasing the length of the output end by multiplying by χ1 to the axis length of the multi-stage 7 / evening part V rubbing rL' / l) / 2 parts; Nori/Dabu 1
The structure was restored, and the actuator's Ill I! IJ i, nc bi! −, an olfactory junction containing a large number of cuts as an f circuit; I, it is necessary to change the song one time. These seven songs were created in view of the above facts, and their main purpose is to skillfully solve the above-mentioned shortcomings of floating in public actuators, and to make the output widths of the two actuators similar to each other. It is possible to move substantially synchronously and uniformly regardless of the magnitude of the resistance, and also without making the construction complicated and expensive, and without requiring a complicated and expensive control fluid pressure circuit. This is a new idea and one concern, since it is possible to make the moving process length of the output end of the 21 hardener longer in relation to the dimensions of the actuator and the dimension in the longitudinal direction of the load, compared to known actuators, without having to use the actuator. The present invention provides a 4vTc body pressure actuator with a 21-pin output end. The Vζ twist of the present invention is "rod side end", head: I+, li

A reciprocating and auxiliary fluid pressure actuator is provided that does not require being fixed to a built body. In the forward operation of the present invention, if the body pressure actuator is also used, the above-mentioned 7 points and 7 points form the output terminal 11. When the above-mentioned entrance/exit hole which is fitted in the sill/rib is busy and the 1' movement and f force is applied, the sill/rib is moved 71 times against the fixed piston. At the same time, the cylinder 7 and the plane cylinder (1) are moved, and therefore the output J in the 2+ direction is moved and assisted (G, respectively). Regardless of the thickness or usage of the negative 1 or resistance, it is carried out evenly by rotating the output end to 4. The length is not limited to half of the length in the 1% m direction of the solinoda, but can be longer than that.
