Problems solved by technology

Here, however, for a given installation space (dimensions of the discharge channel) which cannot be increased, the reed 1 becomes stiffer, ie bent with a smaller radius of curvature
However, this leads to increased bending stresses in the reed 1 and thus to a reduced service life of the reed 1

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] Figure 3a shows a side sectional view of a reed discharge valve according to a first embodiment of the present invention, Figure 3b An isometric view of a reed discharge valve according to a first embodiment of the invention is shown. A reed discharge valve is provided as a housing for closing and opening the compression cylinder of the compressor ( figure 1 : discharge opening ( figure 1 : reference numeral 4).

[0032] If according to figure 1 , 2a Like the prior art of 2b, according to Figure 3a and 3b The embodiment of the reed discharge valve also has a discharge opening for closing and opening not shown here ( figure 1 : the reed 1 of reference num...

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) for opening and closing the discharge opening (4), a bridge (2) for limiting deformations of the lamella (1) in an open state of the discharge opening (4), and at least one securing element (3) for securing the bridge (2) to the housing (9) of the compression cylinder. The bridge (2) has a support surface (5), which faces the lamella (1) and has a specified curvature radius (gamma), in one region, and the lamella (1) is provided with at least one opening (6), which is designed to allow the securing element (3) to pass through the lamella (1) in order to secure the bridge (2) to the housing (8) of the compression cylinder.

Description

technical field [0001] The invention relates to a reed discharge valve, in particular a reed 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 often used, which have a working cycle with a suction process, a compression process and a discharge 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 Figure 2b Consists...
