Is moved by the operation of the first actuator (21), and the pipes (34) (35) from the flow path switching valve (31) are directly connected to the second actuator (26). It is connected. Therefore, the pipes (34) (35) become a separate system from the pipes (32) (33) for the first actuator (21), and the pipes (34) (35) are movable by using a flexible tube or the like. Since the parts have to be provided, there are problems that the piping work is troublesome, the occupied space is large, the tube hangs down to give a messy appearance, and the maintenance is complicated.

[Problems to be solved by the device]

In view of the above points, the present invention provides a piping facility in which a movable part such as a flexible tube can be omitted from the piping around the composite actuator, and moreover, it can be easily retrofitted to the existing composite actuator. The purpose is to do.

[Means for solving the problem]

To achieve the above object, the piping equipment of the present invention comprises a first actuator having a fixed portion and a movable portion,
Plumbing equipment to be attached to a composite actuator having a pair of ports and a second actuator having a fixed portion and a moving portion attached to the moving portion of the first actuator, the piping equipment including a pair of ports A fixed port member attached to a fixed portion of the first actuator and a pair of ports, and a movable port member attached to a moving portion of the first actuator or a fixed portion of the second actuator, and one end Is fixed to any one of the fixed port member and the moving port member and connected to the port,
The other end is slidably inserted into the other end, and a pair of pipe members connected to the port are provided.

[Action]

In the piping equipment of the present invention having the above-described structure, the fixed port member is attached to the fixed portion of the first actuator, the moving port member is attached to the moving portion of the first actuator or the fixed portion of the second actuator, By connecting the switching valve and the port of the fixed port member with a pipe, and connecting the port of the moving port member with the port of the second actuator by a pipe, a movable part such as a flexible tube is omitted from the pipe around the composite actuator. And can be easily retrofitted to existing compound actuators.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall view of a composite actuator equipped with the piping equipment (1) according to the embodiment, and FIG. 2 is a single view of the piping equipment (1), Figure 3 shows its internal structure,
The piping equipment generally indicated by reference numeral (1) includes a fixed port member (2) attached to a fixed portion (22) of the first actuator (21) and a moving portion (23) of the first actuator (21). A moving port member (9) attached to
A pair of pipe members (12) fixed to the moving port member (9) and slidably inserted in the fixed port member (2).
(13) and have. The fixed port member (2) is provided with a pair of ports (3) and (4) and chambers (5) and (6) communicating with the ports (3) and (4), respectively.
Pipe members (12) and (13) are slidably inserted into (6) one by one. Chambers (5) and (6) are sealing members (7)
It is kept airtight by (8). The moving port member (9) is provided with a pair of ports (10) (11) directly communicating with the pipe members (12) (13).

As shown in FIG. 1, piping (32) (33) from the flow path switching valve (31) to each port (24) (25) provided in the fixed portion (22) of the first actuator (21). The same port switching valve (31) to the fixed port member (2)
Connect the piping (14) (15) to each port (3) (4). Also, each port (10) (11) of the moving port member (9)
To the respective ports (29) and (30) provided in the fixed portion (27) of the second actuator (26), the pipes (16) and (17) are connected to the flow path switching valve (not shown) from the pressure supply source (not shown). 31),
The second actuator (26) via the fixed port member (2), the pipe members (12) and (13), and the moving port member (9).
Supply operating pressure to. By doing this, all the piping (14) (15) (16) (17) that goes around the compound actuator
(32) (33) does not need to have a moving part, so it can solve all the problems associated with installing a moving part such as a flexible tube, and this piping facility (1) is simpler than existing compound actuators. Since it can be retrofitted to the above, it is possible to solve all the problems associated with the installation of the movable portion such as the flexible tube even in the existing composite actuator.
