    摘要： A downhole tool control system for a drill string rotary steerable tool that includes a body having an inner chamber, a piston gallery extending between the inner chamber and a piston port, and an exhaust gallery extending between the inner chamber and an exhaust port. A spool in the inner chamber is movable into a plurality of positions to direct and control the timing and duration of the flow of drilling fluid to energize pistons of the rotary steerable tool, and to de-energize the pistons. The spool includes a first passage in fluid communication with a drilling fluid inlet port but not the exhaust port, and a second passage in fluid communication with the exhaust port but not the drilling fluid inlet port.

    摘要： An autosampler sets an injection valve to be in a sample filling state when a sample loop is filled with a sample, and, after completion of filling with the sample, switches the injection valve to an intermediate state and first connects only one end of the sample loop to a liquid delivery channel and an analysis channel. After the above, the injection valve is switched to the sample injection state and the sample loop is interposed between the liquid delivery channel and the analysis channel, so that the sample is injected into the analysis channel.

    摘要： A housing has a housing main body and an outlet port. The housing main body includes a cylindrical housing inner wall that defines an internal space therein. The outlet port fluidly connects the internal space and an outside of the housing main body to each other. The valve has a valve body rotatable about an rotation axis along a rotation axis of the cylindrical housing inner wall. The valve is configured to selectively open and close the outlet port depending on a rotation position of the valve. The housing inner wall is formed such that a distance between the housing inner wall and the axis of the housing inner wall varies in a circumferential direction.

    摘要： A diverter/mixing valve is provided that includes a main outer housing and a barrel assembly disposed inside the main outer housing. When actuated, an actuator rotates the barrel assembly between an open end inlet position where a first fluid stream flows into a first inlet port and a second fluid stream is blocked from flowing into a second inlet port, and an open side inlet position where the second fluid stream flows into the second inlet port and the first fluid stream is blocked from flowing into the first inlet port.

    摘要： A valve device for controlling a fluid flow, in particular an air flow, having at least one inlet and at least two outlets, at least one of the outlets being fluidically connectable in each case to the inlet via a through-channel of at least one manipulable guide means. The through-channel of the guide means can be changed at least indirectly via a control fluid flow either with regard to at least a section of its internal cross section or can be rotated at least to a limited extent with regard to its orientation with respect to the outlets and the inlet can be rotated at least to a limited extent.

    摘要： A valve comprising housing body, partition plate, and collecting device. The housing body defines a housing cavity. The partition plate is provided in the housing cavity. A leakage passage extends along the partition plate through the housing body. The collecting device comprises a lower piece, an upper piece, and a connector connecting them. The upper piece and the lower piece cover a leakage passage upper port and a leakage passage lower port, respectively. The lower piece comprises a collecting cavity communicating with the leakage passage lower port. The lower piece and lower part of the housing body are provided with lower fitting assembly. The upper piece and upper part of the housing body are provided with an upper fitting assembly. The lower piece and the upper piece are fitted on the housing body in place by means of the lower fitting assembly, the upper fitting assembly and the connector.

    摘要： A valve timing controller includes: a driving-side rotating body rotating in synchronization with a crankshaft of an internal combustion engine; a driven-side rotating body disposed coaxially with a rotation axis of the driving-side rotating body and rotating integrally with a valve opening and closing camshaft; advancing and retarding chambers formed between the driving-side and driven-side rotating bodies; a control valve unit controlling supply and discharge of a fluid to and from the advancing and retarding chambers; and a check valve unit disposed upstream of the control valve unit in a supply flow passage. A pressure space is provided between the control valve and check valve units, the control valve unit has a flow passage structure, and the check valve unit includes a supply flow passage and a return check valve.
