Abstract

Mando hidráulico para una combinación (13, 15) de freno y embrague que puede accionarse hidráulicamente para el árbol (12) de accionamiento de una prensa mecánica, con una fuente de fluido de presión que presenta una bomba hidráulica (25) y un acumulador hidráulico (26) para el suministro de un actuador hidráulico (18) con fluido de presión, con una disposición (44) de válvula de seguridad que presenta una conexión (43) de alimentación, a través de la cual conduce una vía de corriente desde la fuente (25, 26) de fluido de presión al actuador hidráulico (18), y con una válvula (33) de presión regulable, en dependencia de cuyo ajuste puede impulsarse el actuador hidráulico (18) con distintas presiones de trabajo, caracterizado porque la válvula de presión es una válvula (33) reguladora de presión de 3 vías con una conexión (32) de presión que puede ponerse en comunicación con la fuente (25, 26) de fluido de presión, una conexión (40) al tanque y una conexión (42) de regulación comunicada conla conexión (43) de abastecimiento de la disposición (44) de válvula de seguridad.Hydraulic control for a combination (13, 15) of brake and clutch that can be operated hydraulically for the shaft (12) of a mechanical press, with a source of pressure fluid that has a hydraulic pump (25) and a hydraulic accumulator (26) for the supply of a hydraulic actuator (18) with pressure fluid, with a safety valve arrangement (44) having a supply connection (43), through which a current path leads from the source (25, 26) of pressure fluid to the hydraulic actuator (18), and with an adjustable pressure valve (33), depending on whose adjustment the hydraulic actuator (18) can be driven with different working pressures, characterized in that the Pressure valve is a 3-way pressure regulating valve (33) with a pressure connection (32) that can be communicated with the source (25, 26) of pressure fluid, a connection (40) to the tank and a connection n (42) connected withthe control connection (43) supply arrangement (44) safety valve.
