    Hello every one I've a solenoid 24v dc and I want to have a continuous reciprocating move Forward & Reverse with adjustable speed regulator.
    Waiting for your help .. Thanks alot

    First, if it's a simple solenoid, you can only control motion in one direction. In or out. Mechanical means are necessary to return the solenoid to its starting position*.

    Note that solenoids are relatively slow devices and current hungry. If you drive them with an astable miltivibrator, you will need driver circuitry to actually power the solenoid and protect the oscillator from back end.

    * there are dual solenoid devices for reciprocating motion.

    Tell us what you are trying to do. A solenoid sounds like the wrong solution.

    Usually a proportional valve is used for position and/or speed control of a cyclinder/solenoid etc.
    If hydraulics are not present then a motorized linear actuator might be the answer, you can achieve the motion you state in the OP.

    The application is :
    http://www.automaster-tw.com/productsDia.php?pn=1384
    which is pumping grease into a system using compressed air in the reciprocating move .. So I thought I can exchange the compressor with a solenoid making the reciprocating move I want ..
    thanks

    well ,, Yes it is very simple solenoid just two cables , 24v dc


    Thanks

    well , I want it to be powerful and fast maybe 10 times per min




    Thanks

    Use a simple motorized rotary to linear Piston for increased leverage over a straight solenoid/piston.

    That air operated pump likely generates a very large amount of force to pump grease and would thus require a very large solenoid.
    I agree with Max, that something like a screw driven linear motor would work better to drive the piston.

    Crank method on the right.
