Definitions

  • a multiway control valve for controlling the oscillatory movement of the piston of a hydraulically or pneumatically actuated oscillator in such manner that the period of oscillation of the piston movement-of the oscillator is independent of the velocity of the piston.
  • the control valve comprises a valve housing and a fluid actuated control piston arranged for reciprocating movement in the housing. A longitudinally extending recess is provided at each end of the control piston,
  • the springs press against the edge of the respective recess in the control piston to restrain the movement of the piston until the force acting on one end'of the piston exceeds the spring force, at which time the relevant spring is then laterally compressed and slides into the recess of the piston so as not to restrain the piston.
  • This invention relatesto a multiway control valve for a pneumatically or hydraulically actuated oseillator ,'suchval ve comprising a valve housing and a control piston which is movable for reciprocation'in the housing.
  • a multiway control valve for a pneumatically or hydraulically actuated oscillator which comprises a valve housing, a control piston arranged for reciprocation in the housing, andmeans arranged to automatically impose a restrain on the movement of the control piston in both its directions of movement.
  • the pipes 7' and 3 are also in communication with the pipe connecters 14a and 14b respectively by way of throttling valves 23 and 24 connected into the pipelines 21 and 22 respectively.
  • control piston 5 is held in its left-hand end position by means of the spring 18b; which has its open end arms pressing against the edgeof the recess 13b in the piston 5, until a pressure is ex erted-on the other end' of the piston which is sufficient to over-

  • FIG. 2 is a flow diagram for the actuation of an oscillator constructed as adouble-acting cylinder
  • FIG. 3 is a flow diagram for'the" actuation of an oscillator constructed as a single-acting cylinder; and e v FIG. 4 shows a collet spring as well as a pipe connecter formed with ahosegrip.

  • the five-way control valve 1 shown in FIG. 1 comprises a housing 2 closed at'both ends by respective end plates land 4.
  • a pneumatically or hydraulically actuated control piston 5 is mounted within a cylindrical control chamber 12 in' the'housthrough a five 'way control valve in ing 2.
  • control piston 5 has a recess 13a and-13b at each end thereof and moves back and forth in the control chamber 12 between its terminal rest positions whenit abuts the end plates 3 and 4 respectively.
  • a pipe connecter 14a, 14b is screwed into each of the end plates 3 and ⁇ .
  • Each of these pipe connecters 14z'1 and 14b isdesigned to be coupled to theend of a pipe or hos'eand is provided with aretain- 20 has finished, pressure builds up at thepipe connecter 16b of the valve 1 until the restr'aint'exerted on the control piston 5 back towards its left-hand end position.
  • the period of oscillation of theipiston 20 can be regulated by means of the two throttling valves 23 and 24. These can be so adjusted that the duration of the movement of the piston 20 in each of the two directions is either the same or is longer in one direction than intheother. 1 r
  • a single-acting cylinder 26 can be used as the oscillatorinstead of the double-acting piston and cylinder shown in FIG. 2.
  • the control piston 5 of the control valve 1 is located in its one terminal positionin which it rests against the left-hand end plate 3 as shown in FIG. 1.
  • the oscillator 19 has ports 7" 8" at opposite 7, pipe 30,, and throttling valve 31 to the pipe connecter l6a1of the control piston 5 until the restrainton the movement of the piston in the "opposite direction due to the spring 18b is removed and the control jpiston 5 is again displaced into its right-hand end position. Then begins a new working cycle.
  • the period of oscillation of the piston 27 can be regulated by means of the throttling valves 28 and 31.
  • Control of the oscillatory movement of the piston 20 or 27 can be effected in both embodiments without throttling valves, in which case the strength of the springs 18a and 18b is chosen so that the force exerted by the springs is overcome at a predetermined pressure.
  • FIG. 4 shows a hose grip 32 having a circumferentially ridged peripheral surface which may be usedinstead of the pipe connecters 14b and 14b.
  • This FIG. also shows a collet spring 18 which is inserted in the bore 33 of the hose grip and is fixedly held therein, and which exercises the check or restraint on the movement of the control piston of the valve 1.
  • control valve 1 described herein can also be used for hydraulic control functions, in which case the actuation of the control piston 5 is likewise carried out hydraulically.
  • a pressure reservoir must be provided in each of the pipe lines leading to the pipe connecters 14 a and 14b in order to balance out any pressure surges.
  • a fluid responsive control valve comprising a housing including opposite endswalls, said housing being provided with a longitudinal channel, a piston including opposite end portions slidably supported in said channel for movement between said opposite end walls, an inlet port provided in said housing in communication with said channel, in outlet port provided in said housing in communication with said channel, a return port provided in said housing in communication with said channel, a pair of resilient members supported in said housing and extending in said channel, each of said resilient members including a secured portion and a restraining portion for engagement one with each of said opposite end portions of said piston, said resilient means acting to restrain the longitudinal movement of said piston in said channel toward a respective one of said opposite end walls, said restraining portion of each of said resilient members being deformable laterally of said channel, said restraining portion upon being laterally deformed beyond a prescribed magnitude acting to substantially free said piston from longitudinal restraint, and means for receiving the laterally deformed restraining portion of each of said resilient members after the restraining portion has been laterally deformed beyond said prescribed magnitude
