Abstract: An electric stepping motor, operated by command signals from a computer or a microprocessor, rotates a rotary control member of a distributor valve, for sequencing hydraulic pressure and hence flow to the cylinders of an axial piston hydraulic machine. A group of the cylinders are subjected to pressure and flow and the remaining cylinders are vented to a return line. Rotation of the rotary control valve member sequences pressurization by progressively adding a cylinder to the forward edge to the pressurized group and removing a cylinder from the trailing edge of the pressurized group. The double ended pistons of each new pressurized group function to drive a wobble plate into a new position of equilibrium and then hold it in such position until another change in the makeup of the pressurized group. These pistons also displace hydraulic fluid from the opposite cylinder head which serves as the output of a pumping element. An increment of displacement of the wobble plate occurs in direct response to each command pulse that is received by the stepping motor. Wobble plate displacement drives the rotary valve of the hydraulic power transfer unit, causing it to transfer hydraulic fluid from a first expansible chamber on one side of a piston in a hydraulic ram to a second expansible chamber on the opposite side of the piston. Reverse drive of the hydraulic power transfer unit reverses the direction of transfer of hydraulic fluid between the two expansible chambers.

An increment of displacement of the rotary pressurized group. An increment of displacement of the rotary hydraulic motor occurs in direct response to each command pulse that is received by the stepping motor. In an installation which includes two hydraulic motors connected to a common output, the rotary distributor valve functions to alternate driving pulses of hydraulic pressure and flow between the two motors.

Abstract: A relatively expensive, relatively heavy, and relatively nonflammable hydraulic fluid (chlorotrifluorethylene) is used in an aircraft ground wheel brake system between the piston (72) of a deboost device (68) and a set of wheel brakes (196). A relatively cheaper and relatively lighter, conventional hydraulic fluid (MIL-H-5606), which is also relatively flammable, is used in the remainder of the system. A replenish system for the relatively nonflammable fluid includes a reservoir divided into two chambers by a piston. One chamber contains a quantity of the relatively nonflammable fluid and the other chamber is connected to the system pressure. The deboost device includes a replenish valve which is opened in response to a position of the deboost piston. Replenishment only occurs when the brakes are applied and replenishment is necessary. At other times, all portions of the brake system are at return pressure. The relatively nonflammable hydraulic fluid acts as a buffer between heat generated at the brakes and the relatively flammable fluid.
