Abstract

"MOTOR DE CURSO VARIáVEL E VáLVULA". Um eixo de válvula de fluido (16) é fornecido para um motor de curso variável (10). O eixo da válvula (16) tem um alojamento (12) formando um cilindro (14), uma primeira entrada de fluido (18) dentro do cilindro (14), uma primeira saída de fluido (20) fora do cilindro (14), uma segunda entrada de fluido (22) dentro do cilindro (14) e uma segunda saída de fluido (24) fora do cilindro (14). Fornecido dentro do cilindro (14) está o eixo da válvula (16) fornecido com fendas (26),(28),(90) e (92). Quando o eixo da válvula (16) gira em uma primeira posição, a comunicação de fluido entre a primeira entrada de fluido (18) e a primeira saída de fluido (20) é cortada, enquanto a comunicação de fluido entre a segunda entrada de fluido (22) e a segunda saída de fluido (24) é aberta. Quando o eixo da válvula (16) gira para uma segunda posição, a comunicação entre a primeira entrada de fluido (18) e a primeira saída de fluido (20) é aberta, enquanto a comunicação entre a segunda entrada de fluido (22) e a segunda saída de fluido (24) é cortada. o dispositivo é preferivelmente enganchado em um cilindro de transmissão (48) em comunicação de fluido com a primeira saída de fluido (20) e a segunda entrada de fluido (22). Um pistão (52) é fornecido dentro do cilindro de transmissão (48). Um suprimento de fluido é operativamente acoplado na primeira entrada de fluido (18) e dispositivos (42) são fornecidos para girar o eixo de válvula (16) em uma velocidade constante. Quando a pressão do fluido aumenta, o curso do pistão (52) aumenta, dessa maneira gerando um curso de pistão mais longo, enquanto a velocidade do eixo da válvula rotativa (16) permanece constante."VARIABLE COURSE ENGINE AND VALVE". A fluid valve shaft (16) is provided for a variable stroke motor (10). The valve shaft (16) has a housing (12) forming a cylinder (14), a first fluid inlet (18) inside the cylinder (14), a first fluid outlet (20) outside the cylinder (14), a second fluid inlet (22) inside the cylinder (14) and a second fluid outlet (24) outside the cylinder (14). Supplied inside the cylinder (14) is the valve shaft (16) supplied with slots (26), (28), (90) and (92). When the valve shaft (16) rotates in a first position, the fluid communication between the first fluid inlet (18) and the first fluid outlet (20) is cut off, while the fluid communication between the second fluid inlet (22) and the second fluid outlet (24) is opened. When the valve shaft (16) rotates to a second position, the communication between the first fluid inlet (18) and the first fluid outlet (20) is opened, while the communication between the second fluid inlet (22) and the second fluid outlet (24) is cut. the device is preferably hooked onto a transmission cylinder (48) in fluid communication with the first fluid outlet (20) and the second fluid inlet (22). A piston (52) is provided inside the transmission cylinder (48). A supply of fluid is operatively coupled to the first fluid inlet (18) and devices (42) are provided to rotate the valve shaft (16) at a constant speed. When the fluid pressure increases, the piston stroke (52) increases, thereby generating a longer piston stroke, while the speed of the rotary valve shaft (16) remains constant.
