Bujão de Restrição fabricados em aço Inox e aplicados em Acoplamentos Hidráulicos Tipos PMV, PMVV, PMVVS operados à água ou óleo, estes elementos controlam os tempos de partidas conforme necessidade através de uma passagem em um furo calibrado em diversos diâmetros.
Its manufacturing is special and requires high levels of precision so that the design acceleration curves are respected.
The number of plugs and its respective holes chosen determine the speed at which the oil passes from the delay chamber to the working chamber, thus defining the start up times.
For changes in the start up time of a hydraulic coupling, there is no need for disassembly. Only by changing the nozzle screw, using a different bore diameter, is it possible to change this parameter.
The usual thread is M16x1,5, with the following bore diameters (mm):
- Unbored
– Ø 1,5
– Ø 1,8
– Ø 2,0
– Ø 2,5
– Ø 3,0
– Ø 3,5
– Ø 4,0
– Ø 4,5
