Abstract: A method controls a compressor for delivering a pressure medium into a pressure medium system, for example an air suspension system in a motor vehicle. In the method, the delivery of the pressure medium can be switched on and off as a function of a temperature signal by the compressor temperature being measured by a temperature sensor which is arranged on the compressor and the switching on and off of the compressor is controlled by an electronic control unit. The switching-on time duration and/or the switching-off time duration or the switching-off and/or the switching-on temperature are/is determined from the rise of the compressor temperature which is measured at short time intervals.

Abstract: A sealed compressor is provided with a temperature sensor biased against an outer surface of its shell. By biasing the temperature sensor against the shell, good contact between the temperature sensor and the shell is ensured. Also by use of molded material around the senor, the sensor is insulated from ambient air, increasing the accuracy of the sensor.

Abstract: A hydraulic pump system is provided that includes a pump driven by an electric motor. The electric motor includes windings that receive power from a power source. In one example, a temperature sensor is arranged in proximity to hydraulic fluid associated with the pump, such as at an input of the pump. In another example, the temperature sensor measures the ambient temperature to predict the viscosity of the pump based upon cool down rates of the system. A controller monitors a temperature at the temperature sensor and commands power to be provided to the windings to generate heat. Electric motor power consumption can be monitored to determine viscosity. The heat reduces the viscosity of the hydraulic fluid. Bleed air may be selectively provided to a casing associated with the hydraulic fluid in response to a command from the controller. The controller actuates a valve to regulate the flow of bleed air to the casing to provide supplemental heat to the heat provided by the windings. In this manner, the viscosity of the hydraulic fluid is more efficiently managed to provide desired startup of the pump in cold conditions.

Abstract: An apparatus for detecting the presence of an overheat condition in a fluid pump includes a pump head for receiving a fluid at a first pressure and outputting the fluid at a second pressure that is greater than the first pressure. A motor is positioned adjacent the pump head to drive the pump head to pressurize the fluid. A single overheat sensor senses an overheat condition in the pump head and an overheat condition in the motor. When a threshold temperature is sensed by the overheat sensor, a switch is activated to prevent operation of the motor. In one embodiment, the overheat sensor and switch are integral and may, for example, take the form of a bi-metal switch formed in the stator windings of the motor. In alternate embodiments, the overheat sensor and switch are separate.

Abstract: An air compressor includes a crankcase, a cylinder secured to the crankcase, a crankshaft disposed inside the crankcase and adapted to be rotated by a drive means, a piston reciprocatively installed inside the cylinder, and a connecting rod for connecting the crankshaft to the piston. Part of the drive power circuit of the drive means is constructed so as to be cut off when displacement of the constituent members of the compressor other than predetermined displacement occurs and/or when the temperature inside the compressor rises above a predetermined value. Thus the passage of electric current to the drive means is cut off, the compressor being brought to a halt without causing secondary damage to develop.
