摘要： A pneumatically actuated reciprocating fluid pump and shuttle valve combination is pneumatically shifted by pressurized air that exhausts from a respective pressurized bellows, diaphragm, or piston chamber, as the bellows, etc. nears the end of its pressure stroke (the exhaust stroke of the pumped fluid). This pressurized air exhausts from the bellows chamber via a shifting piston and cylinder mechanism within the bellows chamber that opens the bellows chamber at a specified location or point in the pump pumping cycle. The pressurized air exhaust from the bellows chamber acts on the end of the shuttle valve spool element to shift the spool element to its opposite position, which reverses the application of pneumatic pressure and atmospheric exhaust between the two bellows chambers to actuate the reciprocating pump.

摘要： A high efficiency, low cost fluid pressure engine. This engine converts reciprocating piston motion to rotary output in a novel manner. The engine comprises at least two parallel pistons adapted to reciprocate in cylinders within an engine block closed by upper and lower heads. Each piston is rigidly secured to a piston rod located along the cylinder centerline and extending through substantially fluid tight packing in the lower head. The lower end of each piston rod is flexibly connected to a first connecting means which also includes an opening surrounding a first crank pin. A pair of reciprocating valve means, located within said engine block, are adapted to selectively introduce and exhaust the engine drive fluid into and out of the cylinder above and below the pistons. Valve push rods secured to said valve means are connected to a second connecting means which also has an opening surrounding a second crank pin. Swinging link means are provided interconnecting each of said first and second connecting means and the engine housing to constrain the movement of the piston rods and valve push rods to substantially linear motion. The first and second crank pins are mounted on a crank plate offset from an output drive shaft so that as steam or another fluid drives the pistons, linear motion is converted to rotary output motion. The output drive shaft is supported by a single main bearing which surrounds the output shaft where it passes through the wall of the engine housing. For greater power, a number of these engine units may be ganged.

摘要： A fluid operated linear actuator control system for drive arrangements of the type wherein two fluid operated linear actuators act upon a shaft at an angle with respect to each other for causing rotation thereof is disclosed. The control system includes a fluid pressure source including a reservoir means, fluid passages connecting the pressure source with each of the fluid operated linear actuators, and control means for communicating the first of the linear actuators with fluid from the pressure source and fluid from the other with the reservoir means to displace the drive arrangement through a first arc sector, and for changing-over the communication to communicate the reservoir with fluid from the one actuator and the other actuator with fluid from the pressure source causing displacement of the drive arrangement through a second arc sector, wherein one of the actuators is in a driving mode while the other actuator is in a floating mode. According to a preferred embodiment, the control enables the drive arrangement to be locked in a fixed position via the use of piloted check valves in the fluid passages and cam switches are utilized to achieve the afore-noted change-over of communication between the actuators and the reservoir and pressure source. The control system is particularly applicable for use with linear actuators for an X-Y axis antenna drive arrangement.

摘要： An electrohydraulic actuator has a power piston which is controlled from movement between the ends of its travel for performing work by servo control valve. When the actuator is not performing work, the power piston is abutted on one side by a pressure positioned centering piston which prevents the movement in one direction. High pressure fluid operates on the other side of the power piston to prevent movement in the other direction so that the power piston is centered in the cylinder and cannot be moved by external forces.

摘要： A device for controlling hydraulic motors as in an aircraft "fly-by-wire" system wherein redundant hydraulic motors and controls are required to protect against failure of portions of the system or device. The device includes two master valves for controlling flow of fluid to and from the motors, one controlled by electrical signals from a command station and the other controlled mechanically through manual or automatic operation. There is a transfer valve for selecting which of the master valves is to be operable and to provide for smooth transition of control from the electrically controlled valve to the mechanically controlled valve. The electrically controlled valve is positioned by means of an articulated command shaft of hybrid force displacement summing structure having redundant hydraulic drive units each controlled by redundant electro-hydraulic servo valves and wherein failed servo valves are accounted for in the force displacement summing structure in a manner to avoid the need for rapid failure detection and correction.

摘要： A safety control system for a pneumatic or hydraulic control circuit has at least one control valve arrangement connected to at least one pickup for monitoring or sensing at least one specific operational condition and for releasing at least one measurement signal, as a function of the operational condition, to the control valve arrangement, which releases a control signal for the actuation of at least one pneumatic or hydraulic correcting element. An indicator circuit is connected to the control valve arrangement for releasing warning signals indicating a disorder, at least in the case of a defect in the control valve arrangement. A control valve is provided between the pickup and the control valve arrangement to simulate briefly the operational condition for the purpose of testing the operational capability of the control valve arrangement.

These pistons are actuated by a high pressure gas through a pair of upstream fixed orifices and a pair of downstream variable orifices or a pair of ball poppet valves operable by a poppet flapper. The flapper is displaced by a pair of low pressure pistons which are driven by a beam deflection fluidic amplifier.
