  • 2 is the piston
  • 3 is the delivery valve at the top of the piston
  • 8 is its seat
  • 4 is the suction valve with its seat
  • 5 is the piston rod
  • 6 is a lining covering the cylinder'wall
  • 7 is a liner in the skirt of the piston.
  • the linings 6 and 7 and the valve seats 8 and9 are made of silicon carbide.
  • the valve bodies 3 and et may consist of the same material.
  • the liner 7 of the piston 2 may be subdivided into a plurality of rings 10 as shown in Fig. 2, this-arrangement being generally preferable to a liner made in one piece.
  • F ig. 3 13 is a flap valve which is hinged to a seat 14 at 15.
