摘要： A gas-pressure-driven apparatus includes a main body having a working chamber, a movable member moving relative to the main body with a pressure of the working chamber, a pressure sensor for detecting the pressure, a flow rate sensor for detecting the flow rate of the working gas. A method for controlling the apparatus includes calculating a pressure change amount from the detected pressure and an integrated flow rate from the detected flow rate when the pressure is changed in a state in which the volume of the working chamber cannot be changed, calculating an initial volume of the working chamber from the pressure change amount and the integrated flow rate, and calculating a post-change volume of the working chamber from the integrated flow rate and the initial volume after creation of a state in which the volume of the working chamber can be changed from the initial volume.

摘要： A method and an apparatus for controlling the function of all kinds of reciprocable power machines which are actuated by pneumatic, hydraulic of any other pressure fluid, irrespective if the machines are of rotary or axially operating type, in which the active power stroke is accomplished using full power of pressure fluid against a reciprocatable piston (2) in the active air pressure chamber (10, 12), and in which the reversing of the direction of operation is made by alternatingly supplying pressure fluid to the opposite air pressure chamber (12, 10) of the machine. A valve poppet (6) having several channels alternately places one of the pressure chambers (10, 12) of the reciprocatable fluid actuated machine (1, 2) under full pressure, builds up a certain counter pressure in a pressure chamber which is, at the actual moment, inactive, and evacuates the pressure from an inactive pressure chamber of the fluid actuated machine.

摘要： A lean-burn internal combustion engine capable of stably securing a satisfactory vacuum for a vacuum actuator which uses a vacuum in an intake manifold disposed on the side downstream of an intake air amount control mechanism, while preventing a deterioration of a specific fuel consumption and a drivability of the engine. A filling state of gases in the intake manifold is controlled based on pieces of information in respect of an engine operating state and a reduction in vacuum, whereby a vacuum such as to ensure the operation of the vacuum actuator is secured. A control for inhibiting a lean-burn operation of the engine and for suppressing an EGR amount or inhibiting the EGR is made in accordance with an braking manipulation, the ON/OFF state of a vacuum switch, or an output from a vacuum sensor at the time of lean-burn operation.

摘要： A method of controlling a cylinder apparatus includes the steps of supplying compressed air of a first high pressure to one chamber of a cylinder which is divided into two chambers by a piston, and exhausting air from the other chamber so as to move the piston from the start position at an end portion of one chamber toward an end position at an end portion of the other chamber along the extending direction of the cylinder, and detecting if the position has passed the position of a sensor. In addition, a moving speed of the piston is decreased by supplying air of a second high pressure lower than the first high pressure to the other chamber after an elapse of a predetermined wait time from when the piston has passed the position of the sensor, so that the piston reaches the end position in a shock-free state.
