Abstract: A flow control valve unit includes a pressurized fluid inlet, a pressurized fluid outlet, a pressurized fluid chamber in which is positioned a stationary seat member, a partition member dividing the pressurized fluid chamber into a first section in constant communication with the inlet and a second section that communicates with the outlet via a center opening in the stationary seat member, an orifice for communicating said first and second sections to each other, and a through hole formed in the partition member. A movable rod is positioned within the pressurized fluid chamber and extends through the through hole in the partition member. The movable rod has a sealing portion at one end for opening and closing the center opening in the stationary seat member during movement of the stationary member. A spring is operatively associated with the movable rod for urging the movable rod in a direction which causes the sealing portion to close the center opening.

Abstract: An electromagnetically actuatable disc-type valve includes a pre-assembled hydraulic sub-assembly with a core member and a separately pre-assembled electrical sub-assembly with a body. The exterior surface of the core member is configured to facilitate insertion into the electrical sub-assembly and orientation relative thereto by use of a bushing. The outside diameter of the body of the valve is no more than 13.5 millimeters in the vicinity of the delivery end of the hydraulic sub-assembly. A fluid filter is disposed between a tensioning spring and a calibration slide to facilitate more accurate flow checking and leakage checking of the valve during manufacture.

Abstract: An access plug is provided for use in oil pans, transmissions and other fluid containers of equipment and the like. The access plug is weight imbalanced along the longitudinal axis to prevent inadvertent rotational movement of the access plug as may occur from vibrational forces when the plug is not properly tightened. By designing the plug with such an imbalance, the plug will terminate its rotation as the weighted half reaches the lowermost point during removal rotation and will so remain, preventing complete removal and rapid fluid loss.

Abstract: A water outlet fitting with a transmitter, a receiver and an electronic circuit for the contactless operation of an integrated non-return valve, in which the circuit is designed for operation in a plurality of selectable functions. On the fitting there is a manually operable switch, especially a push-button which, when operated, can issue setting commands in the form of switching pulse groups in order to select and activate a given function.

Abstract: Instead of wrapping the air hose around the portable tire inflator housing to store it, an internal storage compartment is provided. A guide device in the compartment guides the hose so that it travels a path which is offset downward from a straight line path between its attachment to the compressor of the inflator and the opening in the compartment top wall. This path reduces pulling stresses on the attachment, assists in manual incremental feed of the hose back into a concealed storage position, and prevents the hose from bunching up into upper corners of the compartment. When in its storage position only the air chuck at the end of the hose is exposed.

Abstract: A locking mechanism for male and female coupling members for use in undersea production and drilling applications is disclosed. At least one pin extends radially from the female member. Each pin enters a slot in a guide sleeve extending longitudinally from the male member. The guide sleeve also contains a spring and spring plate. The female member is inserted into the guide sleeve, compressing the spring, and the pin enters the first longitudinal portion of the slot. The female member may be rotated with respect to the male member when the pin is in the circumferential portion of the slot. The pin then may enter the second or third longitudinal portion of the slot. When the pin is in the second portion of the slot, the female member is "parked" or secured to the male member while coupling member valves remain closed, and when the pin is in the third portion of the slot, the valves are open.

Abstract: A solenoid valve (10) for use in an electronic shift control system of an automotive automatic transmission. The solenoid valve includes a body (12) having a cylindrical chamber (34) in which a movable armature (34) is slidably received and which is in communication with an inlet (96) for the automatic transmission fluid and an outlet (104). The body defines a cylindrical valve seat (88) in which a cylindrical valve member (90) coupled to the armature is slidably fitted. The valve member has a control port (92) opening onto the circumferential outer surface thereof and an inner passage (94) communicating the control port with the inlet (96). The solenoid valve is operable to control the fluid pressure substantially proportionally to the axial movement of the armature even in a condition in which a large amount of air bubbles are contained in the automatic transmission fluid.

Abstract: A solenoid unit includes a plurality of solenoid valves having respective valve bodies for attachment with a main casing of an automatic transmission and a case equipped with the solenoid valves in a manner that the solenoid valves can be installed in the main casing collectively. In the unit, the wiring for the solenoid valves has been completed in the casing prior to assembling the unit to the automatic transmission unit. With the arrangement mentioned above, if only attaching the solenoid unit to the main casing, it is possible to assemble the valve bodies of the solenoid valves to the main casing with a predetermined arrangement. Further, since the wiring for the solenoid valves has been already completed in the case, it is possible to omit the post-operation, such as soldering.

Abstract: An automatically switching valve measures pressure at an outlet line using an electric, pressure-sensitive switch which can be set to close at a predetermined pressure threshold within relatively narrow tolerances such that a pressure regulator can be placed between the pressurized gas supply tanks and the switching valve. Closing of the pressure-sensitive switch in response to the drop in pressure below the predetermined threshold sends an electric signal to a relay. In response to the electric signal, the relay causes a different inlet line to be selected, thus changing the particular pressurized gas supply from which the outlet line receives pressurized gas. When gas is supplied through a first inlet line, an electric signal from the pressure-sensitive switch causes the relay to toggle to supply gas through a second inlet line. A subsequent signal from the pressure-sensitive switch causes the relay to toggle back to again supply gas through the first inlet line.
