Abstract: Embodiments of the invention provide a pump control circuit for use with a pump. The circuit includes a pressure sensor capable of sensing a pressure in the pump and a microcontroller coupled to the pressure sensor and to the pump. The microcontroller switches operation of the pump between a high-flow mode and a low-flow mode. When in the high flow mode, the microcontroller limits a current provided to the pump to a high-flow current limit value that is not dependent on the sensed pressure. When in the low flow mode, the microcontroller limits the current provided to the pump to a low-flow current limit value that is less than the high-flow current limit value and that changes depending on the sensed pressure.

Abstract: A rinsing device, in particular for endoscopy, comprising an electrically driven pump, in particular a peristaltic roller pump, as well as a method of operating such a device. A control device is provided to detect and/or adjust a flow rate. In order to avoid an excessively high pressure in case of an unintended stenosis, e.g. kinking of the supply tube, or also intended stenoses, e.g. insertion of a narrow rinsing probe, a current-measuring device is provided to detect a current being received by the pump. The control device is adapted such that when the flow rate exceeds a prespecified limiting value and at the same time the current exceeds a first predetermined current value, the flow rate is reduced to a safe flow-rate value.

Abstract: In a pump control apparatus that controls the discharge of brake fluid using the rotation of a motor, the number of windings in a low speed circuit is set such that the motor operates at a second rotation speed when the low speed circuit is connected to a power supply. A high speed circuit shares a portion of the windings of the low speed circuit so that the motor operates at a first rotation speed when a power supply voltage is supplied to an input terminal which is disposed midway in the windings of the low speed circuit. An ECU determines the load state of the motor based on a difference between the output voltage at an output terminal and the power supply voltage.
