<p>The Engine Head Valve Re-assembly Device consists of a base (1), a guide (2), a holder (3), a presser (4), a height-adjusting bolt (5), a handle (6), a fixing bolt (7), an electromagnetic armature (8) and a spring (9). Detachably fixed to the base (1) is the guide (2) on which the holder (3) is sliding, which contains a presser (4). The action of manual force on the handle (6) is pushing the holder and the presser downwards, whereby the force of the valve spring thereby subdued. The pressed valve spring is retained in a corresponding position owing to the bolt (7) with which the holder (3) is fixed. nd thus easily portable.</p> |
