Definitions

  • the invention relates to a device for interrupting the delivery of a reciprocating compressor according to the preamble of claim 1.
  • the invention is therefore based on the object of creating a device of the type mentioned, in which a compact design is achieved with simple means.
  • the invention has the advantage that in a reciprocating piston compressor for the device according to the invention no significant additional space is claimed, since the auxiliary piston is arranged in an already existing space.
  • the drawing shows a reciprocating compressor for generating compressed air.
  • the reciprocating compressor essentially consists of a cylinder tube 6, a compressor piston 8, which is sealed in this cylinder tube 6, and a cylinder head with a valve device.
  • the cylinder head in turn consists of a cylinder head cover 14 and a valve support plate 9 arranged between the cylinder head cover 14 and the cylinder tube 6 with a suction valve 18 and a pressure valve 13.
  • the reciprocating compressor described is attached to a motor housing 23 of an internal combustion engine, not shown.
  • the compressor piston 8 On the side facing away from the compression chamber 15, the compressor piston 8 is provided with a piston rod serving as an actuating plunger 22.
  • the actuating plunger 22 in turn serves to drive the compressor piston 8.
  • the compression chamber 15 is connected to the atmosphere via the suction valve 18, a bore 16 in the valve support plate 9 and an inlet bore 17 of the cylinder head cover 14. If necessary, the inlet bore 17 can be preceded by an air cleaning filter (not shown).
  • the compression chamber 15 is also connected via a bore 12 of the valve support plate 9, the pressure valve 13 and an outlet bore 11 of the cylinder head cover 14 to a compressed air circuit, which is symbolically represented by a compressed air reservoir 10.
  • a drive device which, for. B. from an internal combustion engine driven camshaft 27 with a cam 1.
  • a compression spring 2 serving as a restoring force is provided, which is arranged between the cylinder tube 6 and a spring plate 25 fastened to the actuating plunger 22 by means of a locking ring 26.
  • the actuating plunger 22 is pressed against the cam 1, so that the compressor piston 8 exerts an oscillating movement when the camshaft 27 rotates.
  • the chamber lying on the side of the compressor piston 8 facing away from the compression chamber 15 is connected to the atmosphere via a bore 24, so that this chamber can be vented and vented without any problems when the compressor piston 8 moves.
  • auxiliary piston 4 which surrounds the actuating plunger 22 and is annular and surrounds the actuating plunger 22.
  • a guide tube 5 which is attached to the cylinder housing and serves to guide the actuating plunger 22.
  • a control chamber 21 delimited by the auxiliary piston 4, which can be acted upon by a control pressure medium via a control input 3.
  • a control pressure medium in the present case this is compressed air
  • the auxiliary piston 4 moves upward towards the compressor piston 8.
  • a sleeve-shaped stop 20 attached to the auxiliary piston 4 and surrounding the actuating plunger 22 and the guide tube 5 then lies against the compressor piston 8 and moves it upward against the force of the compression spring 2 in the compression direction until the compressor piston 8 reaches the dead center corresponding to the compression process, ie top dead center.
  • the effective area of the auxiliary piston 4 acted upon by the control pressure medium and the pressure of the control pressure medium are dimensioned such that the compressor piston 8 is held securely by the auxiliary piston 4 in its top dead center as long as the control chamber 21 is acted on by the control pressure medium .
  • the compressor piston 8 is also not moved during this time, in which the compressed air supply is interrupted, i. H. there is no wear due to a piston movement.
  • the camshaft 27 is relieved of the forces acting on it when conveying compressed air.
  • the stop 20 is designed to be correspondingly short or a stop 7 is provided on the compressor piston 8 or on the actuating plunger 22 which is connected to the guide tube 5 or a corresponding other counter-stop of the cylinder housing comes to rest before the compressor piston 8 strikes the auxiliary piston 4.
  • a pressure regulator device to regulate the pressure prevailing in the reservoir 10, a pressure regulator device, not shown, with a pressure regulator is provided.
  • the changeover signal of the pressure regulator when the prescribed pressure in the reservoir 10 is reached is used to control the control pressure medium for the auxiliary piston 4.
  • the reciprocating compressor is automatically in his after reaching the desired pressure in the reservoir 10 by stopping the compressor piston 8 top dead center switched off. If the pressure mentioned in the reservoir 10 drops, the control chamber 21 is vented by switching the pressure regulator mentioned, so that compressed air is then replenished.
