Portable electrohydraulic trainer

Apparatus for training an operator in use of electrohydraulics comprising:

• a portable support including a rectangular enclosure having an operator panel on one wall of said enclosure,
• an electric-motor/hydraulic-pump integrated within a unitary housing along with an internal fluid sump, said unitary housing being mounted on a second wall of said enclosure contiguous with said one wall,
• an electrohydraulic valve on said support preconnected to said pump with at least one solenoid responsive to electronic valve control signals for controlling said valve to supply fluid from said pump,
• a hydraulic load on said support preconnected to said valve for mechanical motion as a function of fluid supplied by said valve,
• electronic control means on said support within said enclosure and responsive to command signals for generating said valve control signals,
• command means on said panel responsive to an operator for generating said command signals,
• a plurality of electrical connectors on said operator panel individually preconnected behind said panel within said enclosure to said command means, said control means and said at least one solenoid,
• means for selectively interconnecting said connectors externally of the enclosure, and
• a second panel on said enclosure adjacent to, parallel to and extending from said operator panel, said electric-motor/hydraulic-pump housing and said valve being disposed behind said second panel and preconnected to each other by means inaccessible at said operator panel and said second panel, said load comprising a hydraulic cylinder mounted in front of said second panel above said operator panel.
