摘要： A control module adapted for use as either a master controller or device controller in a distributed electrohydraulic system includes a microprocessor-based control circuit with digital memory having stored therein a plurality of programs for controlling operation of the controller in a variety of applications. A plurality of analog inputs provide a mechanism for connecting sensor signals or the like to input ports of the control microprocessor. A plurality of electrohydraulic valve driver circuits have inputs for receiving valve control signals from the control microprocessor, and outputs for selective connection to electrohydraulic valves coupled to the devices to be controlled. Serial communication circuitry is coupled to the control microprocessor and adapted for connection to a high-speed electrohydraulic bus. A plurality of control routines are prestored in a memory library, as is an executive routine that is employed for operating the microprocessor whether the controller is configured as a master or a device controller. To configure a controller for operation as a master controller or device controller, and to configure the controller for operation in association with a specific type of electrohydraulic device or devices, a selectively programmable and reprogrammable subroutine list coordinates the executive routine with the various control subroutines in the control library for interrelating the analog input signals, the serial communication signals and/or the valve control output signals so as to dedicate operation of the controller as a master controller or as a device controller for a specific type of electrohydraulic device.

摘要： A multiplexed hydraulic control system which avoids the use of a rotary multiplexer and thereby allows for random selection of the multiplexed outlet ports and variable dwell times for the respective ports. A single hydraulic input is multiplexed among a plurality of hydraulic outputs. A control system provides two types of signals: (1) modulation signals selected from a plurality of multiplexed input signals for producing a modulating hydraulic flow, and (2) selector signals for operating on the multiplexer means to route the modulated signal to the appropriately selected channel.

摘要： An apparatus providing for the generation, control and application of power to a cyclic functioning machine, using fluids under pressure to transmit and control energy by means of a rotary, segmented cam wheel. The cam wheel provides a plurality of interchangeable segments formed into a rim portion with axially spaced complementary counteracting cam faces formed about opposite rim ends. An individual cam follower, carried on a piston rod of a related hydraulic cylinder, coacts with each of the cam faces to accurately regulate the flow of hydraulic fluid to and from a working cylinder of a machine to provide timed and synchronized machine functions through the control movement of the working cylinder. The contoured configuration of the cam faces are arranged to provide for a desired acceleration and retardation of machine motions. Further, variable speed drive means, employed to drive the cam wheel, provides a timing adjustment between machine cycles.

摘要： Apparatus is provided featuring a signal processor or processing module configured to receive signaling containing information about a pump no flow idle (NFI) state when the pump is running at a pump idle speed; and determine corresponding signaling containing information about whether the pump should remain in a no flow shutdown (NFSD) state or the pump NFI state, based upon the signaling received. The signal processor or processing module is configured to provide the corresponding signaling containing information about whether the pump should remain in the NFSD state or the NFI state.
