摘要： This invention aims at providing a hydraulic circuit apparatus for supplying pressurized fluid into cylinders for a work implement arranged such that during normal operation of the work implement the flow rate of fluid discharged by a pump is controlled such that the difference between the discharge pressure of the pump and the load pressure is always kept constant, whilst during inching operation of the work implement the flow rate of fluid discharged by the pump is reduced. This circuit apparatus comprises a large diameter piston (9) for actuating a displacement regulating member (8) of a variable displacement pump (2) in a direction as to reduce the displacement of the pump; a small diameter piston (10) having pressure receiving chamber (10a) connected with discharge passage (2a) of the pump and adapted to actuate discharge regulating member (8) in a direction as to increase the displacement of the pump (2); a load sensing valve (11) for connecting or disconnecting pressure receiving chamber (9a) of the large piston (9) with or from the discharge passage; and apparatus (12, 13, 14) for applying a force to the load sensing valve to push its spool in a direction as to communicate the discharge passage (2a) of the pump with pressure receiving chamber (9a) of the large piston.

摘要： This invention provides a hydraulic circuit apparatus arranged such that when each of operating valves is operated suddenly, the stability of each of actuators is improved, and when the operating valves are kept at their neutral positions, the flow rate of fluid discharged by a variable displacement pump is increased to improve the response of the hydraulic circuit, and when the actuators are supplied with pressurized fluid, pressure compensation is made by pressure compensating valves. This hydraulic circuit apparatus comprises a bleed-off circuit (11) connecting the discharge passage (1a) of the variable displacement pump (1) with a fluid tank; a bleed-off valve (12) provided in bleed-off circuit (11) and adapted to be kept at its communicating position (I) when the operating valves (2) assume their neutral positions, and also kept at its shut-off position when the operating valves assume either their first fluid supply positions or their second fluid supply positions; and a flow restrictor (13) provided in the bleed-off circuit.

摘要： A hydraulic circuit arranged to prevent the load pressure in one of the hydraulic actuators at the time of starting from becoming abnormally high thereby preventing fluid under pressure from being relieved by the safety valve when a plurality of hydraulic actuators are operated at the same time, wherein the function of one of the pressure compensating valves is temporarily enhanced by introducing the load pressure in the hydraulic actuator so as to supply a large quantity of fluid under pressure to the hydraulic actuator connected to the pressure compensating valve so that the operating speed of the hydraulic actuator can be increased. This hydraulic circuit comprises a compensation pressure selecting valve adapted to supply normally the highest load pressure to the spring chambers of the pressure compensating valves, and supply the load pressure in the hydraulic actuator connected to each of the pressure compensating valves to the spring chamber of each of the pressure compensating valves when either one of the operating valves is operated for the full stroke.

The apparatus of the present invention comprises a yellow phosphorus vapor-providing section in which yellow phosphorus is retained, by which the vapor of the yellow phosphorus is supplied and by which the amount of the vapor of the yellow phosphorus is controlled. The apparatus further comprises a reaction chamber connected to the yellow phosphorus vapor-providing section, in which the light-emitting reaction between the oxygen in the sample and the vapor of the yellow phosphorus is conducted, and a sample gas-supplying section. The amount of the oxygen in the sample gas is determined by measuring the intensity of the light emitted by the reaction by a light intensity-measuring device.
