Abstract

trata-se de uma bomba de pistão axial de deslocamento variável que inclui um bloco de cilindro que define uma pluralidade de furos de cilindro, sendo que cada um recebe um pistão. uma placa oscilante que tem uma superfície de sustentação de pistão é sustentada de modo giratório em relação ao bloco de cilindro. um bloco de porta define as primeira e segunda portas de bombeamento dispostas em comunicação de fluido com a pluralidade de furos de cilindro de modo que, durante a operação da bomba, uma dentre as primeira e segunda portas de bombeamento seja configurada para abastecer com fluido os furos de cilindro para bombeamento, e a outra dentre as primeira e segunda portas de bombeamento seja configurada para receber fluido bombeado a partir da pluralidade de furos de cilindro. a placa oscilante define parcialmente pelo menos uma câmara de controle de volume variável, e a placa oscilante é operável para inclinar em relação ao bloco de porta em resposta a uma mudança de pressão de fluido na pelo menos uma câmara de controle.
