An apparatus for minimizing dead leg spaces in a container or tubing includes a first member having a flange for attaching the first member to a wall of the container or tubing, the flange having at least one aperture, and a second member rotatably coupled to the first member, the second member having an upper end having at least one aperture, and an open distal end. The second member is rotatable relative to the first member between a closed position where the at least one aperture of the second member is misaligned with the at least one aperture in the flange to prevent the passage of fluid, and an open position where the at least one aperture of the second member is aligned with the at least one aperture in the flange to allow for the passage of fluid.

Drain valves with rotatable angled outlets that can be rotated without allowing flow or stopping flow through the valve, containers including the valves, and methods of using the valves, are disclosed.

A valve that includes a housing, a ball having a channel passing therethrough, the ball housed within the housing, a stem extending out from a surface of the ball perpendicular to the channel, a gear coupled to the stem, the gear comprising a number of teeth, and a sleeve having a racked channel defined on an interior surface of the sleeve that interfaces with the teeth of the gear.

The present invention relates to a safety valve (1) having a valve housing (2), in the housing interior of which there is provided a shut-off body (3) which is held in an open position of the safety valve (1) by at least one elastic retention element (4) counter to the force of a medium flowing through the valve housing (2), in which open position the medium flows through a valve opening (5) in the shut-off body (3). Here, the shut-off body (3) is displaceable in the valve housing (2) such that the shut-off body (3), in the event of a pressure drop on its outflow side, moves against a closing body (7) into a closed position of the safety valve (1) in which the closing body (7), which is acted on by at least one resilient pressing element (8), sealingly closes off the valve opening (5) in the shut-off body (3), wherein at least one bypass duct is provided which, in the closed position of the safety valve (1), can be opened to connect the inflow side of the shut-off body (3) to the outflow side thereof until the shut-off body (3), when the pressure has been equalized by the at least one bypass duct, is moved into the open position of the safety valve (1).

A faucet that includes a base configured to detachably mount to a mounting surface; a sleeve coupled to and extending upwardly from the base; a handle body disposed around the sleeve and configured to rotate about a vertical axis, the handle body including a vertical portion and a horizontal portion extending outward from a side of the vertical portion; a first valve disposed within the base; a second valve disposed within the horizontal portion of the handle body; and a spout configured to receive water from the sleeve and direct the water to an outlet of the spout; where the vertical portion of the handle body is configured to be rotated about the vertical axis to control the first valve, and the horizontal portion of the handle body is configured to be rotated about a horizontal axis to control the second valve.

A pneumatic tool includes a housing that contains an installation tunnel, an air supplying channel and first and second air inlets, a control valve installed in the installation tunnel for shifting among first, second and third positions; a controller that is mounted on the control valve and has two paddles; a pushing rod that passes through the controller and the control valve; and a trigger that is attached to the pushing rod. The pneumatic tool provides the controller for a user to selectively operate with his/her left hand or right hand to perform forward/reverse switching and speed adjustment.

A fluid flow control assembly includes a first pipe-in-pipe assembly comprising an inner tubular member disposed in an outer tubular member, wherein the inner tubular member comprises an inner bore and an annulus is formed between the inner tubular member and the outer tubular member, a terminating bulkhead assembly coupled to the first pipe-in-pipe assembly, wherein fluid communication is provided between a bore of the bulkhead assembly and the inner bore of the inner tubular member while fluid communication is restricted between the bore of the bulkhead assembly and the annulus of the first pipe-in-pipe assembly, and an annulus conduit coupled to a radial port of the first pipe-in-pipe assembly, wherein fluid communication is provided between the annulus conduit and the annulus of the first pipe-in-pipe assembly while fluid communication is restricted between the annulus conduit and the inner bore of the inner tubular member.

A quick connector includes a valve body and a rotatable ring fitting over the valve body. The rotatable ring is rotatable with respect to the valve body. When a sealing member of the rotatable ring is rotated to a full open position, an exit end and an entrance end of the valve body are both encompassed by an opening of the sealing member and communicating with each other. When the sealing member is rotated from the full open position to a full close position, one of the exit end and the entrance end is moved out of the opening and blocked by the sealing member, so that the entrance end and the exit end do not communicate with each other.

Valves. At least some of the example valves include: a valve body; a valve housing; and a piston that defines a proximal end and a distal end, the piston disposed in a piston bore of the valve housing. The valve defines a closed orientation by a first rotational orientation of the valve housing relative to the valve body, and the valve defines an open orientation by a second rotational orientation of the valve housing distinct from the first rotational orientation.

Constriction valves for catheters and method of using constriction valves are presented. The catheter valve has a conduit defining a lumen. The catheter also has a spring that is configured to bias the lumen from an open position to a closed position by altering an effective length of the conduit or altering the circumference of the conduit. The spring is further configured to change its configuration by changes of intraluminal pressure of the valve. A user can insert a tool into a catheter having a valve by manipulating the valve to expand a substantially closed lumen by compressing the spring, twisting the spring, or pulling on a cord coupled with the valve.
