Embodiment Construction

[0030] Spatial specifications such as top, bottom, side or the like relate to the description of the reed discharge valve which, as shown in the illustration, is arranged above the compression cylinder and whose reed Also move upwards as shown in the illustration. But these descriptions are not limiting.

[0031] image 3 A side view of a reed discharge valve according to one embodiment of the present invention is shown. A reed discharge valve is provided for closing and opening the compression cylinder in the compressor housing 9 ( figure 1 ) in the discharge opening 4 ( figure 1 ).

[0032] according to image 3 The implementation of the reed discharge valve as per the figure 1 , 2a Like the prior art of 2b, it also has a discharge opening 4 (not shown here) for closing and opening figure 1 ) of reed 1. A single discharge opening can be provided, or alternatively a plurality of discharge openings can be provided, wherein the total cross-sectional area of ​​the disch...

Abstract

The invention relates to a lamellar discharge valve for a discharge opening (4) in a housing (9) of a compression cylinder of a compressor. The lamellar discharge valve has a lamella (1), which has anelongated shape and has openings (6) in the region of the lamella ends, said openings being open towards the ends in the longitudinal direction, for opening and closing the discharge opening (4) anda bridge (2) for limiting a maximum deformation of the lamella (1) in an open state of the discharge opening (4). The bridge (2) consists of two bridge elements (2', 2''), and each of the bridge elements (2', 2'') has an engagement section (7), which faces the housing (9) and is in engagement with the openings (6), and a respective support surface (5), which faces the lamella (1) and has a specified shape for limiting the maximum deformation of the lamella (1) in the open state of the discharge opening (4).

Description

technical field [0001] The invention relates to a reed discharge valve, in particular a reed discharge valve for closing and opening a discharge opening in a housing of a compression cylinder of a compressor. Background technique [0002] Compressors are used, for example, in the braking systems of buses or trucks. This compressor has one or more compression cylinders and is mounted directly on the vehicle's engine. Reciprocating piston compressors are frequently used, which have a working cycle with a suction process, a compression process and an exhaust process. During the operation of the compressor, energy is dissipated by the vehicle engine on the one hand due to compression work and on the other hand due to mechanical losses such as, for example, friction of piston rings or due to the movement of reed valves. Currently, however, energy saving is the main challenge. [0003] In the prior art, a reed discharge valve is known such as figure 1 , Figure 2a and Figur...
