the pressure chamber 23 is closed by a sealing cord 28 which is provided in the corresponding grooves 26, 27 all around the wall in the retaining plate 21 or the end plate 22, with connecting screws 29 tensioning the plates 21, 22 in their area as a compressed air seal for sealing corresponding sealing washers 30 are provided.
the height of the pressure chamber 23 is thus determined via the thickness of these sealing means 28, 30.
the valve 16 which passes through the holding plate 21 in each case has a pressure member 32 which projects into the respective compartment 2, 2 'and is axially movably supported by a valve tappet 33 against a pressure spring 34 which bears against the end plate 22 in the region of a blind hole 31.
the holding plate 21 is connected via guide tubes 38, which are supported concentrically to the respective valve 16 and form the compartments 2, 2 ', to the front plate 4, which has the insertion openings 6, so that the respective overpressure container 3, 3 '.
a guide which securely establishes the compressed air supply connection in the region of the valve 16 is specified and simple handling for the user is thus achieved.
the pressure container 3, 3 ' is provided in the region of its opening edge 39 with a shape extension 40 (FIG. 9), on which a holding bracket 44 carrying the cover 20 can be displaced parallel to the central axis 42 of the respective container 3, 3' and around its displacement axis 43 is pivotally supported.
the cover 20 is pivoted by pivoting a support arm 46 in the direction of arrow 45 by means of the holding bracket 44 into the open position shown, so that the tennis balls 14 located in the container interior are freely accessible.
the holding bracket 44 is introduced in the region of its support arm 46 into a shaped recess 47 (FIG. 2) of the shape extension 40 and is axially movably supported in this by means of a holding member 48.
the retaining bracket 44 is stably clamped to the cover 20 by means of a connecting screw 49, so that the cover 20 is in turn captively connected to the respective overpressure container 3, 3 '.
the locking member 7 provided for fixing the overpressure container 3, 3 'in the insertion position is in an expedient embodiment as a front plate 4 penetrating in the area of an insertion opening 52 on the one hand with an angled locking hook attachment 51 and on the other hand with the Top of the lid 20 connected support strut 53 formed so that the locking member 7 can be brought into the engagement position illustrated on the pressure container 3 'according to FIG. 2.
the sectional view in the area of the lid 20 according to FIG. 2 makes it clear that the lid 20 is provided with a sleeve part 56 which has a support shoulder 54 which can be supported on the opening edge 39 of the respective container 3, 3 'and a cylinder area which can be brought into the interior of the pressure container 55 has (Fig. 3 to 6).
