Abstract: A pipe coupling structure includes an electromagnetic valve and a passage block having an upper surface mounted with the electromagnetic valve and opposite side surfaces formed with an inlet port and an outlet port. The inlet port is connected to a PCV pipe through an inlet pipe joint, and the outlet port is connected to a PCV pipe through an outlet pipe joint. At least one of the inlet pipe joint and the outlet pipe joint is a union joint. The union joint includes a hollow cylindrical union end making contact with a first surface formed with the inlet port or a second surface formed with the outlet port and a hollow cylindrical union nut configured to connect the inlet port or the outlet port to the union end.

Abstract: A pipe joint is in such a structure that a sealing (5), an annular chuck (6), and a release ring (4) are inserted into the fitting recess (2) of the joint proper (1). Projecting annular receiving surfaces (601, 602) are provided on the side of the forward end of the annular chuck (6) and an acting surface (301) for diametral contraction is provided on the inner periphery of the fitting recess (2). Pawl parts (603) are formed on the forward end of the annular chuck (6) and the annular chuck (6) is provided with slits (604) for diametral expansion and contraction. With a flexible tube (7) inserted into the fitting recess (2), the annular chuck (6) is diametrally enlarged. In such a state as above, when pressurized fluid is fed, the pawl parts (603) bite into the flexible tube (7). With the release ring (4) thrusted into the fitting recess (2), the pawls (603) are released from biting into the flexible tube (7).

Abstract: A braking device of a rodless cylinder, wherein a movable member (3) which is located outside the main body (1) and movable together with the piston (2) is connected to a piston (2) movably provided in a main body (1) of a cylinder. A brake rail (8), extending in parallel to a moving direction of the piston (2), is located on the outer surface of the main body (1) of the cyclinder. A brake member (16) is engageably or disengageably opposed to the brake rail (8) and moved by a working member (17) to a braking position where the brake member (16) is engageable with the brake rail (8) or to a non-braking position where the brake member (16) is disengageable from the brake rail (8), to thereby perform braking or brake releasing of the movable member (3).

Abstract: A butterfly valve includes a purge gas flow path supplying a purge gas for preventing inflow of a control fluid into a magnetic fluid sealing portion from a flow path through an insertion hole. The purge gas flow path is provided with an opening and closing valve for opening and closing the purge gas flow path and a pressure gauge for measuring a pressure value in the purge gas flow path, in the stated order from the upstream side. The purge gas flow path is connected to a portion between the magnetic fluid sealing portion and the flow path of the butterfly valve on the downstream side of the pressure gauge, and communicates with the flow path through the insertion hole. The butterfly valve further includes a control device that controls at least the opening and closing valve. The control device is provided with a monitoring program for monitoring a pressure value.

Abstract: A four-way valve includes a body and a valve component. The body includes a valve chamber and first to fourth communication channels which communicate with the valve chamber at positions arranged in sequence in a predefined rotational direction and cause the valve chamber to communicate with an outside. The valve component is rotatable in the predefined rotational direction and switches the four-way valve to be in at least one of: a first state in which the first and second communication channels communicate with the first region and the third and fourth communication channels communicate with the third region; and a second state in which the second communication channel communicates with the first region, the third communication channel communicates with the second region, and the first and fourth communication channels communicate with the third region.

Abstract: A valve stem is disposed so as to be capable of moving linearly reciprocally in a case connected to a valve section for opening and closing a flow channel. The valve stem is urged toward the valve section by a spring. A manual lever is rotatably supported on the upper end of the valve stem. The valve stem is divided into a first rod part connected to the manual lever and a second rod part positioned on the valve section side, a connecting pin fixed to the first rod part is inserted through an elongated elongated hole formed in the second rod part along an axial direction, and the first rod part is able to move in the range of the elongated hole relative to the second rod section.
