摘要： A first on-off valve (2) and a second on-off valve (3) each are a two-port valve. A first passage block (5) is provided with a first on-off valve-corresponding inflow passage (11) and a first on-off valve-corresponding outflow passage (12). A second passage block (6) is provided with a second on-off valve-corresponding inflow passage (14) and a second on-off valve-corresponding outflow passage (15). The second on-off valve-corresponding outflow passage (15) is in communication with an upstream side portion of the first on-off valve-corresponding outflow passage (12) via a communicating passage (13) formed in the first passage block (5). An orifice (20) is provided between the second on-off valve-corresponding outflow passage (15) and the communicating passage (13).

摘要： Inside a cartridge-type cylindrical casing (40), a meter-out inlet (43), a valve chamber (44), a rod chamber (46), and a meter-out outlet (47) are formed in that order. The rod chamber (46) and the valve chamber (44) are arranged substantially concentrically, and a check valve seat (53) is provided on an inner peripheral surface of a peripheral wall (44a) of the valve chamber (44).

摘要： A method of controlling insulating fluid flow between fluid channels in sections of an electrical power cable at different elevations, the channel of one section being isolated from the channel of a next adjacent section by a hydraulic stop, to limit the loss of insulating fluid when a seciton is ruptured and yet permit a limited flow from the point of rupture to protect the cable from contamination. Fluid at a high rate from a lower section to adjacent higher sections around the stop is permitted by a check valve which substantially prevents fluid flow in the opposite direction and a flow-limiting valve permits fluid flow at a low rate from the higher section to the lower section. The fluid pressure difference between the sections may be relieved by a relief valve if the difference exceeds a predetermined amount.

摘要： Apparatus and method are disclosed by which a pent up supply of compressed air in a pneumatic supply line is slowly bled off after the line is disconnected from its air supply source. The apparatus and method are well adapted for use in pneumatic tool lines. The invention includes a housing which may be inserted in a line attached to a supply of high pressure air, such as a pneumatic line. Flow restriction means are contained in a passageway within the housing for permitting the relatively free flow of pressurized air in one direction, such as is needed to operate a pneumatic tool, and for partially restricting the flow of air in the opposite direction once the line has been disconnected from its supply source. The flow restriction means incorporate a movable member which allows air to freely flow around it when the line is operating a tool, but allows only limited air flow in the opposite direction when the moveable member is forced against a seat, thus gradually, rather than immediately, releasing compressed air trapped in the line to avoid fishtailing of the line.

摘要： A series of hydraulic shock absorbers all using the same piston. This is attained by giving no damping function to the liquid passages in the pistons, by which all pistons can be provided with an equal number of passages with a fixed, relative large cross-section. Thus, all pistons are equal. The damping function is taken over by an annular damping member between the piston and the valve.

摘要： The valve provides an unrestricted flow through a chamber from a first opening to a second opening while the reverse flow is first adjusted to a fine extent so as to allow a gradual increase in flow until full throughput is reached. To this end a large primary closing member engages the first opening so as to be urged off its seat under the action of the fluid entering said opening whereas the opposite flow seats said primary closing member. For this opposite flow, a control member causes a secondary closing member constituted by a rod coaxial with the primary control member to recede out of a port formed in the primary member. When said rod has receded sufficiently and allowed a sufficient throughput, it draws along with it the primary closing member which leads to the desired full throughput in said opposite direction.
