    Abstract: It is a question of a pneumatic drive system comprising at least one pneumatic drive (2) possessing a drive housing (4) and an output drive unit (6) able to be shifted in relation to it by the action of compressed air, the output drive unit (6) including an output drive piston (8), which in the drive housing (4) separates two working chambers (12 and 13) from one another, one or both of such chambers being connected with a pneumatic control line (17 and 18), such line having control valve means (22 and 23) able to be switched over between an air economy position and an open position (24) making available a flow cross section which is larger than that of the air economy position, such control valve means being provided with actuating means (32) able to be activated in a manner dependent on the position of the output drive unit (6), such actuating means being able to cause a switching over of the control valve means (22 and 23) into the air economy position, when the output drive unit (6), owing to the compressed air flowing through the control valve means (22 and 23) into the pneumatic drive (2), has reached an end of stroke position or a position just short thereof. The air economy setting has the particular feature that it is in the form of a choking setting (25) opening up a flow cross section which is smaller than in the open position (24).

    Abstract: A pressing machine with fewer breakdowns in a hydraulic pressure compensating device for a pressure-equalizing apparatus for pressure pins is provided. For this purpose, a hydraulic pressure compensating method includes the steps of connecting the pressure-equalizing circuit (42) and the oil feeding means (25) according to hydraulic pressure of the pressure-equalizing circuit (42) and predetermined preloading pressure at an outlet port of the oil feeding means (25) to thereby set the hydraulic pressure of the pressure-equalizing circuit (42) at the preloading pressure, when the hydraulic pressure of the pressure-equalizing circuit (42) decreases after the completion of a forming operation from peak pressure at the time of completion of the forming operation and becomes smaller than a predetermined value, and after setting the same at the preloading pressure, disconnecting the oil feeding means (25) and the pressure-equalizing circuit (42), and continuing the disconnection until the hydraulic pressure of the pressure-equalizing circuit (42) in an next forming. operation decreases from the peak pressure and becomes smaller than the predetermined value once again.

    Abstract: A latch valve of the slide type is provided in the air storage chamber of an air-operated cylinder and piston tool which requires a percussive or striking action followed by return to a condition prepared for subsequent and rapidly repeated action. In the returned and prepared condition the latch valve captures a charge of compressed air in the storage chamber while exhausting the cylinder so as to permit the preceding return stroke. In the fired condition the latch valve opens the storage chamber directly into the cylinder while closing the exhaust. In one form the latch valve includes a port that opens into a return air reservoir when in the fired condition to charge the same. In another form the latch valve includes a transfer tube that cooperates with said port to exhaust the return air reservoir after each full cycle of operation.
