PRESSURE BOOSTER FOR DRIVING HYDRAULIC TOOLS

Abstract

A pressure booster for driving hydraulic tools has a gas or air pressure-driven pneumatic unit with a system line attaching to a compressed air inlet. An hydraulic unit is connected to the pneumatic unit. The hydraulic unit has a hydraulic connection to the fluid-tight connection of the hydraulic tool to the hydraulic unit. To provide a pressure booster which enables the use of electrically operated functional components independent of an external electrical connection, it is provided that a compressed air generator connected to the compressed air inlet is connected to an internal electrical consumer and/or a connection unit for connecting an external electrical consumer.

Claims

1. A pressure booster for driving a hydraulic tool, the pressure booster comprising: a gas or air pressure-driven pneumatic unit with a system line connected to a compressed air inlet; a hydraulic unit connected to said pneumatic unit, said hydraulic unit having a hydraulic connection for a fluid-tight connection of the hydraulic tool to said hydraulic unit; a compressed air generator connected to said compressed air inlet, said generator being connected to one or both of an internal electrical consumer or a connection unit for connecting an external electrical consumer.

2. The pressure booster according to claim 1, wherein said compressed air generator has a generator inlet connected to said system line and a generator outlet connected to said system line.

3. The pressure booster according to claim 1, which further comprises a pressure booster housing having said connection unit integrated therein.

4. The pressure booster according to claim 1, wherein said connection unit is disposed on said hydraulic connection.

5. The pressure booster according to claim 1, wherein said internal electrical consumer is at least one device selected from the group consisting of a battery, a data storage unit, a display unit and a communication unit for wireless data transmission.

6. The pressure booster according to claim 1, wherein said connection unit is configured for connection to a hydraulic tool connection unit disposed on the hydraulic tool.

7. The pressure booster according claim 1, wherein said internal electrical consumer is a display unit having an e-paper display.

8. The pressure booster according to claim 1, wherein said hydraulic unit and said pneumatic unit are combined in a single-piece, mobile handling unit.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0028] The figure shows a perspective view of a pressure booster according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0029] Referring now to the sole figure of the drawing in detail, there is shown an exemplary embodiment of a pressure booster 1 in a perspective view. The pressure booster 1 has a compressed air inlet 3 which is connected via a pneumatic system line 8 to an internal hydraulic unit, not shown here, in which the pneumatic pressure is converted to hydraulic pressure.

[0030] A compressed air generator 4 is integrated/inserted into the system line 8. The generator 4 has a generator inlet 6 and a generator outlet 7. The system line 8 is connected to the generator inlet 6 and to the generator outlet 7.

[0031] The compressed air generator 4 generates electric current when flow passes through it. The current is conducted, firstly, via an electrical line 10 to an internal electrical consumer 11 and, secondly, via another electrical line 10 to a connection unit 5a in the pressure booster housing 9. External electrical consumers, i.e. any functional components, can be supplied with current via the connection unit 5a. A further connection unit 5b is connected to the electrical consumer 11 via an electrical line 10, wherein the connection unit 5b is implemented as a digital output through which data stored in the electrical consumer can be read.

[0032] By way of example, the internal electrical consumer 11 may be one or more of a battery, a data storage unit, a display unit (preferably with a low-energy consumption display) and/or a communication unit for wireless data transmission.

[0033] Along with the connection possibility for connecting various functional components to the connection unit 5a, 5b, the pressure booster 1 also has a hydraulic connection 2 through which a hydraulic toolnot shown herecan be supplied with hydraulic pressure.
