Abstract: A hydraulic system in which the reversal of direction of a hydraulic motor therein is accomplished by a changeover control unit which comprises a four-way, changeover valve having changeover passages connecting the motor with a fluid pressure supply line and a discharge line. A restrictor provided for controlling flow in the discharge line is variably opened and closed in response to operation of the changeover valve. A metering valve in the control unit is responsive to pressure drops across the restrictor and operates to bypass supply fluid to the discharge line downstream of the restrictor to change over without damage to the system.

Abstract: The invention relates to a hydrostatic-steering system having two or more motors for the power steering of two or more wheels, or two or more pairs of wheels. The motors are arranged in parallel in a hydraulic circuit and a metering type control device operated by a steering wheel is used for controlling the distribution pressurized hydraulic fluid to the motors. A fluid stream quantity divider is utilized to supply equal quantities of pressurized fluid to the motors. Each of the motors has valve means associated therewith having two or three operative positions including a neutral or bypass position. The other operative positions facilitate the operation of a motor such that the turning of the steering wheel in one direction effects the operation of the motor in a selected one of two possible directions. With this arrangement, for example, it is possible to have the front wheels of a vehicle turn in one direction and the rear wheels of the vehicle turn in either selected direction as desired.

Abstract: THE INVENTION RELATES TO A HYDROSTATIC STEERING SYSTEM FOR HEAVY VEHICLES. THE SYSTEM COMPRISES DUAL UNITS IN SERIES WITH ONE UNIT BEING A WORKING UNIT AND THE OTHER UNIT BEING A CONTROL UNIT. EACH UNIT INCORPORATES CHANGEOVER AND SHUT-OFF VALVE MEANS AND METERING MEANS. A STEERING WHEEL ACTUATES THE CONTROL UNIT AND THE METERING MEANS OF THE CONTROL UNIT ACTUATES A CONTROL MOTOR WHICH IN TURN ACTUATES THE METERING MEANS OF THE WORKING UNIT. THE METERING MEANS OF THE WORKING UNIT ACTUATES A WORKING MOTOR CONNECTED TO THE STEERING LINKAGE OF THE VEHICLE.

Abstract: AN ENCAPSULATED REFRIGERATION MOTOR-COMPRESSOR HERMETICALLY SEALED IN A CAPSULE AND IN WHICH THE MOTOR IS COOLED BY A SEPARATE OIL FLOW THAN THAT LUBRICATING THE COMPRESSOR. THE TWO INDEPENDENT OIL FLOWS ARE TAKEN FROM A COMMON OIL PUMP BY A TWIN CENTRIFUGAL PUMP. THE MOTOR HAS A VERTICALLY DISPOSED HOLLOW MOTOR SHAFT TO WHICH IS ATTACHED A LENGTH OF TUBING IN COMMUNICATION WITH THE BORE OF THE SHAFT DEFINING A FIRST CENTRIFUGAL OIL PUMP. A SECOND LENGTH OF TUBING IS MOUNTED CIRCUMFERENTIALLY AND AXIALLY OF THE FIRST-MENTIONED LENGTH OF TUBING SPACED OUTWARDLY THEREFROM DEFINING A SECOND CENTRIFUGRAL OIL PUMP DRIVEN IN CONJUNCTION WITH THE FIRST PUMP FROM THE COMMON MOTOR SHAFT. A SINGLE CENTRIFUGRAL PUMP CONSISTING OF A SINGLE LENGTH OF TUBING CAN PROVIDE THE TWO OILS FLOWS BY CONSTRUCTING IT WITH AN AXIALLY EXTENDING ENLARGMENT AT THE ZONE OF DIVISION OF THE DISCHARGE INTO TWO OUTPUT FLOWS.

Abstract: THE INVENTION RELATES TO A GENERATOR FOR SUPPLYING CONTROL SIGNALS FOR A THREE PHASE INVERTED CONVERTER OF THE TYPE HAVING THREE PAIRS OF JOINTLY QUENCHABLE, CONTROLLABLE RECTIFIERS. THREE SUBSTANTIALLY SQUARE WAVE SIGNALS ARE GENERATED AT A PREDETERMINED FREQUENCY AND DISPLACED FROM EACH OTHER BY 120 DEGREES. STRIKING MEANS RECEIVE THE SIGNALS AND SEPARATE THE UPPER AND LOWER HALVES OF EACH SQUARE SIGNAL AND SEQUENTIALLY DIRECTS THE HALF WAVES TO THE CONVERTER RECTIFIERS. QUENCHING MEANS ALSO RECEIVE THE SIGNALS AND SUMS THEM TO FORM A SUMMATED SIGNAL, THE SUMMATED SIGNAL BEING DIRECTED TO THE CONVERTER FOR JOINTLY QUENCHING THE RECTIFIERS.
