| A compressor capacity control method and a device is provided. The changeover from a loading state regarding the compressor to an unloading state regarding the compressor and vice versa is controlled, whereby, during a time span from a starting time point when the compressor operation state changes into an unloading state to a time point when a loading/unloading operation-cycle is finished and a predetermined time duration has passed after the starting time point, the time cycle control is performed so that the loading state is changed into the unloading state, at a time point when the predetermined time duration has passed. Further, the discharge pressure of the fluid discharged from the compressor is detected so that the loading state is changed into the unloading state in a case where the discharge pressure exceeds a prescribed upper limit pressure. | ||||||

| The engine has an input system formed with a fluid displacement pump that enables substantially continuous pumping from a low-pressure side to a high-pressure side substantially without any backflow or backpressure pulsations. The output system, in one embodiment, is an output system having a turbine rotation about an axis that is substantially orthogonal to the pressure flow originating from the prime mover. The output system may include a first turbine which provides for the mechanical work output of the engine and a second turbine which feeds back to drive the input system. Any increase in the load to be driven by the first turbine translates into a proportional increase in the drive energy fed back to the input system. In an alternative embodiment, a differential may be used to distribute the output power to a load or back to the input compressor. | ||||||

| 17 | Fluid displacement pump with backpressure stop | US10036036 | 2001-12-31 | US06632145B2 | 2003-10-14 | Arthur Vanmoor |
| The fluid displacement pump enables substantially continuous pumping from a low-pressure side to a high-pressure side substantially without any backflow or backpressure pulsations. Liquid or gas is injected to the high-pressure side by way of mutually intertwined worm spindles that form a fluidtight displacement system. The blades of the impeller system are slightly curved from the inside out, i.e., from their axles to their periphery, so as to ensure a tight seal between adjacent blades. The orientation of the blades is almost flat, i.e., their attack angle relative to backpressure is close to perpendicular so that they will turn quite freely in the forward direction, but will not be turned backwards by a pressurized backflow. The impeller rotation that is introduced via the spindle shafts nevertheless leads to a volume displacement towards the high-pressure side, for instance, towards a chamber to be pressurized or to be subjected to equal pressure. | ||||||
| 18 | Screw compressor for refrigerating apparatus | US09884016 | 2001-06-20 | US06484522B2 | 2002-11-26 | Noboru Tsuboi |
| The present invention provides a screw compressor for refrigerating apparatus capable of controlling the rotational speed of a motor to be suitable for cooling heat load by simply controlling an inverter, without causing the overload of the motor. The screw compressor 1A for refrigerating apparatus 10A, which uses a motor 22 controlled by an inverter, as a driving portion, is provided with a suction pressure detector D3 as a heat load detecting means for detecting the cooling heat load; a motor coil temperature detector D1 as a means for detecting the load condition of the motor 22; and a controller 26 that decreases the rotational speed of the motor 22 if the capacity of the compressor is determined as excessive based on a pressure signal from the detector D3, maintains the rotational speed if the capacity is determined neither excessive nor lacking. In case that the capacity is determined as lacking, the controller 26 reduces the rotational speed if the load condition is determined as excessive based on a temperature signal from the detector D1 and increases the rotational speed in the other case. | ||||||

| An auxiliary solenoid controlled variable displacement power steering pump, hydraulic systems incorporating same, and method for improving the efficiency of variable displacement power steering pumps. In one embodiment, a rotor is arranged within a pump body, and a cam fitted on an outer periphery of the rotor and movably arranged within the pump body to form a variable volume pump chamber. The cam is biased towards a position within the pump body to create maximum displacement. A mechanism is provided for forcing the cam into a position of fixed minimum or reduced displacement under certain conditions, such as low engine speed and power steering demand. In a preferred embodiment, the mechanism comprises a solenoid driven connecting rod that is operatively connected to the cam. Activation of the solenoid forces the cam to a position of fixed minimum or reduced displacement. | ||||||

| An improved continuous capacity modulation system for scroll-type compressors is disclosed in which a valve body of a solenoid valve assembly is secured to the inner wall of the hermetic shell and the actuating coil is mounted on the outer surface thereof. The actuating coil includes a plunger/valve member which cooperates with passages provided in the valve body to selectively actuate the capacity modulation arrangement utilizing compressed fluid. The construction offers the advantage that all fluid pressure lines are located within the hermetic shell and thus protected from potential damage, the solenoid coil may be easily changed/replaced to accommodate different available operating voltages and/or malfunction thereof and the system can be easily tested prior to final welding of the outer shell. The actuating coil is controlled by Pulse Width Modulation to reduce the load demand of the compressor during times when load shedding is required. | ||||||
