Abstract

"PISTãO PARA ANEL DE COLETA DE óLEO". A invenção refere-se a um pistão (3) para um motor diesel grande de dois tempos que inclui um anel de coleta de óleo (1) para a formação de um empanque de anel de pistão (2), o dito pistão sendo disposto para ser móvel no estado instalado de um lado para outro ao longo de uma parede do cilindro (4) de um cilindro (5) do motor diesel grande de dois tempos, onde o empanque de anel de pistão (2) inclui um primeiro anel de pistão (7) que está mais próximo a uma câmara de combustão (6) do cilindro (5) com uma primeira superfície de rolamento (701) e também o anel de coleta de óleo (1) com uma superfície de rolamento de anel de coleta (101), e onde o primeiro anel de pistão (7) é disposto em uma primeira ranhura de anel de pistão (702) e o anel de coleta de óleo (1) é disposto em uma ranhura de anel de coleta (102) do pistão (3) de tal modo que, no estado de operação, a primeira superfície de rolamento (701) do primeiro anel de pistão (7) e a superfície de rolamento de anel de coleta (102) do anel de coleta de óleo estejam em contato de atrito com uma superfície de rolamento do cilindro (401) da parede do cilindro (4). De acordo com a invenção, o pistão (3) apresenta uma abertura de óleo lubrificante na região da ranhura de anel de coleta (102), e/ou na ranhura de anel de coleta (102), o pistão (3) sendo projetado de tal maneira que o óleo lubrificante possa ser aplicado à superfície de rolamento do cilindro a partir do interior do pistão (3) através da abertura de óleo lubrificante.
