Definitions

  • Fig; 3 shows another form of construction of the pressure cylinder.
  • a cylindrical projection 1111 has been provided on the cylinder cover 1341. projecting into a cylindrical recess 44 of the piston 17a.
  • the piston is provided wn'th an inner flange 45 contacting the thicker part 10a of the cylindrical shaft 80,.
  • a chamber 44 is formed being connected by a channel 47 with the cylindrical chamber 48; as the construction otherwise fully corresponds with that shown in Fig. 2 for the other parts the same reference numerals are used as in Fig. 2.
  • the oil flowing through the bore 33 will fill the chamber 48 and will flow through the channel 4'7 into the chamber 44 and then through the channel 44a into the piston chamber z.
  • the piston is subjected to the pressure of a spring '74 which tends to hold it in said end-position and the tension of which can be regulated by a manually operable adjusting screw '75.
  • a spring '74 which tends to hold it in said end-position and the tension of which can be regulated by a manually operable adjusting screw '75.
  • the spring '74 is normally so adjusted that it can just stand the pressure exerted upon the piston '70 by the liquid supplied through the pipe p; owing thereto, sucking of the liquid by and into the pump can take place inthe proper manner.
  • a hydraulic driving device in which two auxiliary pistons are connected with the main piston and are subjected to pressure from the same source of pressure, said auxiliary pistons being adapted to shift the main piston during the clamping and the releasing action of the chuck.
  • a hydraulic driving device in which ,two auxiliary pistons are connected with the main piston of smaller sectional area and are subjected to, pressure from the same source of pressure, one of said smaller pistons being adapted to eflect the clamping movement, and the cylinder of the respective piston communicating with the cylinder of the main piston by a small orifice adapted to permit passage of liquid from said smaller cylinder into said larger one in order to increase the pressure therein.
