Definitions

the invention relates to a pressure-actuated rotary drive or adjusting device according to the preamble of the main claim.
a device of this type is known from DE-AS 26 47 385. Since only one drive guide is provided on each piston in devices of this type, tilting moments occur during operation which tend to cause the piston to tilt. This creates high frictional forces, which generate large surface pressures and thus severely impair the efficiency of the device and shorten the service life. In order to keep these disadvantages as low as possible, additional guides are provided in the known device which are laterally offset with respect to the drive guide, but the effect of which is not satisfactory.
the object of the present invention is to increase the operational safety and the service life of the device and to improve its efficiency.
the one Rack-provided guide in its surface facing the cylinder wall has a groove arranged parallel and symmetrically to the cylinder axis, which receives the guide opposite, offset by 180 ° around the cylinder longitudinal axis, in a form-fitting manner without a rack of the other piston.
the invention is further based on the object of damping the movements of the two pistons in their respective end positions, in order thereby to strike the device actuated by the pistons too hard, e.g. a large wiper or the like to avoid.
an additional channel 15 is provided which enlarges the gap remaining of the bore 3 and extends parallel to the cylinder axis, so that the printing medium when flowing into the space formed between the piston crowns does not flow perpendicular to the direction of movement of the two, but rather in the direction of movement of the two pistons and thus supports the diverging movement.
bumps are attached to the outside of the piston crowns to fix springs which run coaxially to the cylinder axis and which are located on the cylinder covers support and return the pistons from the open position to the closed position, in the event that, for example, a pressure fluid leak can no longer build up.
the racks 8 are positively and non-positively fitted into the guides 6, so that they no longer leave their position without additional fasteners even in intermittent operation.
pins 16 can also be provided, which either glue or connect the toothed racks 8 to the guides 6 as dowel pins. If the toothed rack shape is less precisely matched to the shape of the guides 6, the toothed racks are held by means of screws, and forces which want to lift the toothed racks out of the guides only have to be absorbed by the screws.
the guides 6 provided with a toothed rack 8 are provided in their surface facing the cylinder wall with a groove 23 oriented parallel and symmetrical to the cylinder axis, which guides the guide 7 without toothed rack, which is offset by 180 ° around the cylinder longitudinal axis of the other piston in a form-fitting manner.
each guide 6, apart from the groove 23, is equipped with symmetrically arranged guide surfaces 24 which are wide in the direction of the circumference of the cylinder inner wall and substantially exceed the width of the toothed racks.
the piston 5a is designed such that the guide surfaces 17 receiving the seals 1oa and 11a are aligned in such a way that the pistons which are moved towards one another can largely move into one another.
the cylinder cover 2 is then formed accordingly, so that here a overall nu g of finished space for the air inlet is present.
the cylinder cover 2 has a beveled outer recess 18, this recess is stepped in the embodiment according to FIG. 4, so that a grip edge 19 is created in each case.
FIG. 5 shows the embodiment of a device in which springs 2o which are per se belonging to the prior art are used. While in this embodiment the piston is designed, for example, in accordance with the embodiment shown in FIG. 1, but can also be designed in the same way in accordance with the embodiment shown in FIG. 4, the cylinder covers 21 are designed to be large enough to accommodate the springs To create 2o.
a damping device is additionally provided in a modification of the embodiment shown in FIGS. 1 to 5.
the cylinder chamber is penetrated by a web 25, which does not hinder the movements of the guides 6 and which serves to accommodate bores for the pressure medium inlet and outlet lines and which at the same time represents the damper device on one side of the cylinder.
Bores 26 and 27 are provided both in the web 25 and in the cylinder cover 2.
the actual damping device 28 is installed in the piston 5 and, in the exemplary embodiment shown, is formed from two impacts 29 and 30 projecting beyond the piston surfaces on both sides.
the StoßL are dimensioned and arranged so that they are aligned with the bores 26 and 27 and can be inserted into these bores 26 and 27, the bores having sealing rings, so that the bumps L are tightly guided within the bores.
a throttle bore 31 is additionally provided and a bypass line 32, which is formed from a check valve, which in the illustrated embodiment consists of a ball 33 (FIG. 8), which is arranged in a ball cage, which has a valve seat 34 .
the ball In the position shown in FIG. 8, the ball is in a position in which the bypass line is not closed, ie the ball is not located on a valve seat but, for example, on holding fingers which cause the pressure to flow around it make medium possible.
a bypass line 35 formed in the same way is provided in the cylinder cover 2 and a throttle bore 36 is also arranged in the cylinder cover 2, the two components 35 and 36 creating a connection between the cylinder space and the associated pressure medium supply and discharge line.
the ball of the check valve in the bypass line 35 bears against the valve seat, i.e. seals.
