Abstract

a presente invenção refere-se a um cilindro de dupla ação que compreende um alojamento de cilindro, um primeiro pistão oscilante, um segundo pistão oscilante e um pistão central que é móvel para três posições estacionárias ao longo de uma direção de atuação do cilindro. um movimento dos pistões oscilantes no furo do cilindro é delimitado por disposições de batente de extremidade. um movimento do pistão central no furo do cilindro é delimitado pelo primeiro e pelo segundo pistão oscilante. cada pistão oscilante compreende uma primeira seção e uma segunda seção. um comprimento circunferencial dos pistões oscilantes é maior na primeira seção do que na segunda seção. nas primeiras seções, uma primeira vedação está disposta para um engate de vedação com uma parede interna do furo do cilindro. nas segundas seções, uma segunda vedação está disposta para um engate de vedação com a parede interna do furo do cilindro ou uma parede interna do pistão central.
