Abstract
The invention relates to a new type of hydraulic module for actuating at least one hydraulic control element with a hydraulic pump in a housing, with an electric motor fastened to a first housing side for driving the pump, with a tank located on a second housing side opposite the first side for a hydraulic fluid, e.g. hydraulic oil, with flow channels produced in the housing produced preferably by bore holes for the hydraulic fluid to supply this fluid from the tank to a pump chamber, for transmitting the hydraulic fluid conveyed by the pump to a pressure connection located on the housing, for connection of the at least one actuating element and for returning the hydraulic fluid from the pressure connection into the tank.
Claims22
A hydraulic module for actuating at least one hydraulic control element or actuator with a hydraulic pump in a housing, with an electric motor fastened to a first housing side for driving the pump, with a tank located on a second housing side opposite the first side for a hydraulic fluid, with flow channels in the housing produced by bore holes for the hydraulic fluid to supply this fluid from the tank to a pump chamber, for transmitting the hydraulic fluid conveyed by the pump to a pressure connection located on the housing for connection of the at least one actuating element and for returning the hydraulic fluid from the pressure connection into the tank, wherein in the flow channel for returning the hydraulic fluid into the tank there is an electrically controllable or adjustable valve, which is a pressure regulating shut-off valve.
A hydraulic module for actuating at least one hydraulic control element or actuator with a hydraulic pump in a housing, with an electric motor fastened to a first housing side for driving the pump, with a tank located on a second housing side opposite the first side for a hydraulic fluid, with flow channels in the housing produced by bore holes for the hydraulic fluid to supply this fluid from the tank to a pump chamber, for transmitting the hydraulic fluid conveyed by the pump to a pressure connection located on the housing for connection of the at least one actuating element and for returning the hydraulic fluid from the pressure connection into the tank, wherein the tank has a compensating and pressure element producing a primary pressure for the hydraulic fluid.
