Title
(PT) Disposição em um motor a pistão e método de controle dos pistões
Abstract
(PT)
"DISPOSIçãO EM UM MOTOR A PISTãO E MéTODO DE CONTROLE DOS PISTõES". A invenção refere-se a um motor a pistão que na forma de uma bomba de pistão ou máquina a pistão (motor) compreende dois ou mais cilindros de pistões (14b, 14c), de preferência posicionados com as mesmas distâncias angulares de 180 graus para dois cilindros, 120 graus para três cilindros, etc. com relação a um eixo geométrico e cada um compreendendo um pistão alternativo com uma haste de pistão projetante (18b, 18c). Através das hastes de pistões (18b, 18c), a cada pistão é dado um deslocamento controlado correspondido com o dado deslocamento controlado de outro ou outros pistões. O dispositivo de controle é girável e influencia as porções extremas externas projetantes das hastes de pistões ou partes encaixadas nestes, por exemplo, roletes giráveis (20b, 20c). Por intermédio de uma bomba de pistão desse tipo, o pistão deve contribuir para impulsionar o fluxo de fluido, enquanto um motor a pistão desse tipo será projetado para ser acionado por um fluxo de fluido. Condições de operação são objetivadas que proporcionam um fluxo volumétrico mais uniforme, isto é, sem quaisquer flutuações significativas. Com a essa finalidade, o referido mecanismo de controle girável é projetado com uma superfície de came circundante (52) em que as extremidades de hastes de pistões se apóiam por intermédio da superfície periférica dos referidos roletes giráveis (20b, 20c). De acordo com uma característica de um método associado com a aplicação desse motor a pistão, cada pistão pode com vantagem ser acionado em uma velocidade constante através de parte de seu curso de expansão.
