<p>PURPOSE:To make the whole shape small by driving a piston with a driving shaft, radially forming four sliding holes at the interval of 90 deg., and sucking and discharging four pistons in sequence in one rotation of the driving shaft. CONSTITUTION:Pistons 7 are inserted into sliding holes 6 of a block 1 radially formed with a four sliding holes 6 at the interval of 90 deg.. Suction valves 42 and exhaust valves 56 each made of a check valve are provided on the sliding holes 6. The exhaust valves 56 are connected to one discharge port 59. The pistons 7 are driven by a driving shaft 18. Four pistons 7 perform suction and discharge strokes in sequence in one rotation of the driving shaft 18. The whole shape can be made small-sized, and a large displacement can be secured.</p> |
