Abstract
Bomba de pistón de accionamiento múltiple. Destaca por la actuación externa sobre las válvulas de admisión (4) y antiretorno (5), en coordinación con los movimientos del pistón (3), mediante sendos brazos, respectivamente (6) y (7) que están actuados por distintos medios, bien mediante un segundo cilindro hidráulico (8) o bien por otros medios electromecánicos o mecánicos, así como porque intercala, en el circuito hidráulico (12) y (13) del pistón (2) y a partir de la bomba hidráulica (14), un distribuidor (11) de una válvula de cambio automático (10) y una válvula de retención y presión (9), que alimenta al circuito (12) y (13) del cilindro (2) y, también, al circuito (12"'') y (13"'') de un segundo cilindro hidráulico (8) que actúa sobre los brazos (6) y (7), de accionamiento respectivo de las válvulas de admisión (4) y antiretorno (5).Multi-drive piston pump It stands out for the external action on the intake (4) and non-return valves (5), in coordination with the movements of the piston (3), by means of two arms, respectively (6) and (7) that are operated by different means, either by means of a second hydraulic cylinder (8) or by other electromechanical or mechanical means, as well as because it intercalates, in the hydraulic circuit (12) and (13) of the piston (2) and from the hydraulic pump (14), a distributor (11) of an automatic changeover valve (10) and a check and pressure valve (9), which feeds the circuit (12) and (13) of the cylinder (2) and, also, the circuit (12 "'' ) and (13 "') of a second hydraulic cylinder (8) acting on the arms (6) and (7), of respective actuation of the intake (4) and non-return valves (5).
