With this throttle valve, the flow of the medium is interrupted when a corresponding back pressure on the saw blade occurs , until, for example, a particularly hard material area of the sawing material has been removed from the saw band . applied further pressure

As mentioned ₉ , this throttle valve is assigned to the saw band guide 44. This saw band filler 44 is attached to a stationary adjustable masonry part 52 . the action of the saw band guide 44 with the throttle valve 46 is further described in more detail. *

The sliding block is located on the Rüeken beile check constricting in the direction of arrow band saw blade 26 under pressure against the worn. Spring package 144 is pressed = the sliding block, which is made of a Semder material? can vertically enclose the bracket 142 by the distance a relative to ₉ after the throttle valve has already closed. This possibility of the relative movement of these parts to one another is necessary, for example due to large chips present between the saw blades or back pressure caused by hard material spots without any load on the saw band itself, for example. to be able to compensate.

The mode of operation of the throttle valve will now be described «

In the position shown in the drawing, the throttle valve is open, ie the hydraulic medium , for example pressure oil, can pass unhindered from the inflow line 48 via the inflow channel 76 into the channel 72 and from there via the valve chamber 74 or the outflow channel 80 out of the valve = flow ο It can thus fully meet the requirements for the desired
