Document Type and Number:
WIPO Patent Application WO/2012/051974
Kind Code:
A3
Abstract:
The invention relates to apparatuses for increasing the output of hydraulically operated tools, comprising a hydraulic device having at least one pump. Said apparatuses are characterized in particular by a simple implementation. For this purpose, a throttling check valve is arranged downstream of the pump in the direction of the tool, wherein the throttling check valve allows the medium to flow without throttling in the direction of the tool and with throttling in the direction of the pump. The at least one pump of the hydraulic device conveys the medium, in particular in the form of an oil, in the direction of the throttling check valve and the tool. The throttling check valve is installed for through-flow in the pumping direction and as a throttle in the backflow direction. The line in the form of a hose is a pressure accumulator.
