  • the first and second holders 92 and 94 are fluidized using the thrust along the axial direction of the threaded portion 114 when the first and second nuts 126 and 128 are fastened. Since the filter 12, the regulator 14 and the lubricator 16 which are pressure devices can be connected to each other, the filter 12, the regulator 14 and the lubricator 16 can be firmly connected to each other, and the first pressure device can be connected to the adjacent fluid pressure device. A force can be uniformly applied through the first and second holders 92 and 94. As a result, it is possible to connect the fluid pressure devices with a good balance.
  • the first nut 126 and the cap 150 are integrated in advance, the axial alignment of the bolt hole 122 of the first holder 92 and the screw hole 130 of the first nut 126 can be easily taken. Assembly work is easy. Furthermore, the smooth surface formed on the curved surface portion 152, the first side wall portion 154a, the second side wall portion 154b, and further the first flat surface portion 156a and the second flat surface portion 156b of the cap 150 partially covers the first nut 126. Because it is surrounded, there is little accumulation of dust.
  • the pressure fluid is supplied from the pressure fluid supply source (not shown) to the first port 26 of the filter 12 through the pipe.
  • the pressure fluid is introduced into the case unit 22 from the first port 26, and dust and the like contained in the pressure fluid are suitably removed by passing through the filter element of the filter unit 24. Thereafter, the pressure fluid rises in the filter unit 24 and is discharged from the second port 28 as clean pressure fluid.
  • the pressure fluid is supplied to one port (not shown) of the regulator 14 through the hole 98 of the connecting device 18a, adjusted to a pressure value set in advance by the handle 44, and then adjusted pressure.
  • the fluid is supplied via the other port to the lubricator 16 which is integrally connected by the connecting device 18b.
  • the regulated pressure fluid is supplied from the third port 56 of the lubricator 16 and flows to the fourth port 58 side, and at the same time, part of the pressure fluid is supplied to the inside of the case unit 50. Therefore, the lubricating oil is pressed by the pressure fluid supplied into the inner case 64, and the lubricating oil flows to the holder 54 side (in the direction of arrow A) through the oil guide tube 84, and then enters the storage chamber 74 through the oil passage 76. Supplied and dropped into the pressure fluid through the dropping port 78. As a result, when the pressurized fluid passes through the inner member 70 and the lubricating oil is mixed by a predetermined amount, it passes from the fourth port 58 to another fluid pressure device that requires the lubricating oil through the pipe. Supplied.
  • connection apparatus of the fluid pressure equipment is not limited to the above-described embodiment, and it is needless to say that various configurations can be adopted without departing from the gist of the present invention.
  • the lightening portions 170 and 172 are provided outside the first side wall portion 154 a and the second side wall portion 154 b without providing the lightening holes 158 a and 158 b in the cap 150.
  • the connection device can be further reduced in size.
