  • An advantage of the proposed solution is that it allows simultaneous mounting of the filter element and the exhaust cover in the pump, which allows not only savings in terms of manpower, but also in terms of cost and efficiency, since no particular installation is no longer necessary especially inside the pump for the intrinsic fixing of the closure end of the filter element and the axial retention thereof.
  • the exhaust cover and the closure cap are made in one piece to facilitate machining.
  • the exhaust is connected to the end cap using a coupling, which acts as a connecting piece. Whether this connection is arranged integrally or not with the exhaust cover and the closure tip, it preferably allows to integrate other functions such as a noise filter, to fight against more effectively against noise caused by the pump, or

It can also be seen in FIG. 3 the presence of a grid above the baffle 6 in the space available between the closure cap 32 and the exhaust cover 4. This grid constitutes a variant
  • this one makes it possible on the one hand to guide the exhaust flow, and on the other hand, thanks to the successive passage of the air flow in weak and then larger sections, to reduce the sound level.
  • the fact that it is divided into a number of small holes or slots increases the frequency of the generated sound, the range of which is more restricted. , and thus contributing to the same goal of reducing noise pollution.
