Abstract

"INJETORES DE RESFRIAMENTO DE PISTãO COM ENTREEIXO REDUZIDO De acordo com a invenção, um injetor de resfriamento de pistão para motor à combustão interna compreende um corpo de injetor (1), uma placa transversal de fixação (6) e um meio de parafusação, tal como um parafuso de fixação (7) defasado lateralmente segundo um entreeixo (E2). O corpo de injetor (1) comporta uma perfuração axial (2) contendo um meio de válvula (3) , e uma perfuração transversal (4) que recebe um conduto de saída de fluido de resfriamento (5). Em torno da perfuração transversal (4), a parede periférica (1a) é espessa. Em sua posição diametralmente oposta (1c), a parede periférica (1a) é mais fina, devido à presença de uma cavidade externa (1d) diante do parafuso de fixação (7). Pode-se assim aproximar o parafuso de fixação (7), diminuindo o entreeixo (E2), o que reduz o volume global do injetor de resfriamento.
