    Abstract: A variable displacement compressor includes a crank chamber for housing a cam plate, a suction chamber, and a discharge chamber. The apparatus includes a first passage connecting the crank chamber with the discharge chamber to discharge the pressure in the crank chamber to the suction chamber to change the suction pressure. A second passage connects the discharge chamber with the crank chamber to supply the pressure from the discharge chamber to the crank chamber increase the pressure in the crank chamber. A valve is disposed in the second passage to open or close the second passage. When the cam plate speed exceeds a certain predetermined amount, a solenoid is actuated to increase the size of the valve opening. As such, the load on the compressor during high speed rotation of the compressor drive shaft is reduced and the durability of the compressor is increased.

    Abstract: In order to supply a coating to a roller, a coating supplying groove is provided along only one side of a core which is connected to an end of a support so as to act as a shaft of a roller. A coating reservoir between the roller and the core is located to one side of the core. To permit engagement and disengagement between the support and the core, an elastic member is mounted within a coating flowing hole of the core, while an inserting groove and a stopping groove are provided in the inner peripheral surface of the coating flowing hole of the core. To automatically stop and start the supply of coating to the coating roller, and to adjust the flow rate, the number of revolutions of the roller are detected and used to actuate the coating feed mechanism to supply coating at a flow rate corresponding to the number of revolutions and or direction of rotation of the roller.

    Abstract: An apparatus for limiting the power output of a hydraulic system is disclosed. The hydraulic system has a variable displacement pump. The variable displacement pump has a movable swashplate and is driven by a source of motive power. The apparatus includes a memory device for storing a set of power modes. Each power mode has a predetermined power level associated with the hydraulic system and is defined by a plurality of set points. Each set point corresponds to a predetermined flow rate and discharge pressure of the pump. A device senses the speed of the source of motive power and producing a signal representative of the actual speed in response to the sensed speed. A device senses the pressure of the variable displacement pump and produces a signal representative of the actual pressure in response to the sensed pressure. A device senses the swashplate angle of the variable displacement pump and delivers a signal representative of the actual swashplate angle in response to the sensed swashplate angle. A device receives a desired power mode signal having a desired power level. The desired power level is different from the predetermined power levels associated with the set of power modes. A control device receives the actual speed, pressure and swashplate angle signals, and responsively determines a desired flow limit of the pump. The desired flow limit corresponds to the desired power level.

A cylinder block is coupled to the shaft for co-rotation with the shaft within the housing and includes a plurality of cylinders disposed in a circumferential array parallel to and surrounding the shaft axis. A piston is disposed to reciprocate within each of the cylinders and is coupled to a yoke for determining displacement of the pistons within the cylinders. A valve plate is mounted on a valve block and includes kidney-shaped slots for registering with the cylinders as the cylinder block rotates, and thereby connecting the cylinders to pump input and output ports. A microprocessor-based controller is externally mounted on the pump valve block and includes internal memory having various remotely-selectable control programs prestored therein. Sensors responsive to pump operating conditions are connected to the pump control electronics, and include a first sensor responsive to yoke position, a pressure sensor responsive to pump output pressure and a speed sensor responsive to angular velocity of shaft rotation. All of the electronic components are mounted on the valve block.

    Abstract: Raw numerical output data representing the value of a selected function or parameter which varies according to a known relationship with one or more control functions or parameters is monitored and its measured value is normalized to determined the value, i.e. normalized value of the data under preselected standard conditions at which the control parameters have predetermined standard or nominal values. Signals representing the values of the control parameters are produced and converted to correction factor signals representing the deviations, if any, between the monitored and standard values of the control parameters, and the correction factor signals are combined with a signal representing the measured value of the raw output data to obtain a normalized data signal representing the normalized value of the output data. The data normalizing operation may occur in a test mode which provides a readout representing the normalized data value, in a monitoring mode which provides a display representing the raw and normalized data values, the monitored control parameter values, and the parameter correction factor values or furnishes these values to a computer for further processing or to a data bank for storage, or in an adaptive mode which provides error or feedback signals for regulating the control parameters to maintain the latter precisely at or within a given range about their standard or nominal values.
