Booster for a digital hydraulic controller and method for using a booster in connection with a digital hydraulic controller

摘要

A booster for a digital hydraulic controller which has at least one digital valve (40). The booster is connected to a magnetic coil (41) of a valve stem (42) of the digital valve (40) by at least two voltages (21, 22) wherein one voltage (21) is higher than the other voltage (22). The invention also relates to a method for using a booster in connection with a digital hydraulic controller.

主权项

1. A device for increasing the speed of actuation of a multiplicity of digital valves arranged as a digital valve group such that the multiplicity of digital valves are connected in parallel in relation to a fluid flow source, the device comprising:
a first cable connection point, having a multiplicity of discrete first wire connectors for receiving a control signal; wherein the device has for each of said multiplicity of discrete first wire connectors, a corresponding second cable connection point, each second cable connection point having a second wire connector and a third wire connector; a first current supply having a first voltage and connected to a ground and having a first current output; a second current supply having a second voltage connected to the ground and having a second current output; wherein the second voltage is higher than the first voltage of the first current supply; an electric circuit for each discrete first wire connector and the corresponding second cable connection point, the electric circuit further comprising: a first electrical connection between one of said second wire connectors and the first current output without a switch therebetween; a first semiconductor switch between the ground and the third wire connector; a second semiconductor switch between the second wire connector and the second current output; and a pulse former connected by an electrical conductor to each discrete first wire connector to receive a control signal, and connected to the first semiconductor switch and the second semiconductor switch, to close the first and second semiconductor switches for a first time period and to close only the first semiconductor switch during a second time period.
