According to an aspect, an inflatable penile prosthesis includes a fluid reservoir configured to hold fluid, an inflatable member, and a pump assembly configured to transfer the fluid between the fluid reservoir and the inflatable member. The pump assembly includes a valve body, a pump bulb, and a deflation mode actuator. The valve body includes a bi-directional valve configured to move from an inflation position to a deflation position in response to an activation of the deflation mode actuator. The bi-directional valve in the inflation position is configured to open a fluid passageway in the valve body to transfer fluid from the pump bulb to the inflatable member. The bi-directional valve in the deflation position is configured to open a fluid passageway in the valve body to transfer fluid from the inflatable member to the fluid reservoir that bypasses the pump bulb.

The present disclosure relates to a hydrostatically adjustable flow control valve. In one embodiment, the valve includes a fixed sleeve that slidably receives a spool. A spring biases the spool relative to the fixed sleeve. A primary orifice is used to deliver fluid to the interior area of the fixed sleeve and spool. A control device is used to selectively vary the rate at which fluid drains from the interior area. Draining the fluid results in the spool being received within the interior of the fixed sleeve. The movement of the spool opens flow ports within the sleeve. This, in turn, allows fluid to exit the valve. Conversely, the control device can be set to prevent fluid drainage. This results in the spool extending from interior of the fixed sleeve, the closure of the flow ports, and the sealing of the valve.

A valve assembly and an ink cartridge with the valve assembly are provided. The valve assembly includes a valve cover, a valve base, a diaphragm and a transfer column. The valve cover is disposed on the valve base to define a valve cavity, and the diaphragm is disposed between the valve cover and the valve base and configured for separating the valve cavity into a first deformable cavity and a second deformable cavity independent with each other. The transfer column is fixed in the valve cavity and penetrates through the diaphragm, and at least one of the transfer column and the diaphragm is provided with a passage. The diaphragm moves relative to the transfer column due to a pressure difference between the first deformable cavity and the second deformable cavity, resulting in opening or cutting off communication between the first deformable cavity and the second deformable cavity by the passage.

An adjustable multiple bladder system for an article of footwear is disclosed. The bladder system includes an outer bladder that may be inflated using an external pump. A valve member is disposed within the outer bladder and divides the outer bladder into two distinct inflation chambers. The inflation chambers may be inflated separately.

A reservoir refill system for an electronic vaping device includes a refill container and a reservoir. The refill container contains a pre-vapor formulation. The refill container includes a body, an opening in the body, and a first interlocking ring including at least one groove or at least one protrusion therein. The reservoir is configured to contain a pre-vapor formulation and includes a reservoir body, an opening in the reservoir body, and a second interlocking ring including at least one groove or at least one protrusion therein at an opening of the reservoir. The first interlocking ring is configured to mate with the second interlocking ring so as to release the pre-vapor formulation from the refill container to the reservoir.

A control valve assembly includes a valve body defining an inlet, an outlet and a fluid flow pathway therebetween. A ball valve is positioned within the fluid flow pathway and includes a rotatable ball having an inlet opening, an outlet opening and a flow pathway therebetween, an upstream seat ring positioned at an inlet side of the ball, and a downstream seat ring positioned at a downstream side of the ball, the seat rings being configured to substantially seal off fluid flow between upstream and downstream sides of the ball except through the ball fluid flow pathway. At least one of the upstream and downstream seat rings is a dynamic sealing seat ring. A retainer ring is positioned between the dynamic sealing seat ring and a portion of the rotatable ball to substantially prevent deformation of a portion of the dynamic sealing seat ring in a direction toward the ball.

A ball for a valve assembly, a valve assembly comprising such a ball, a machine comprising such a valve assembly and a method of operating such a valve assembly. The ball comprises a first bore for communicating fluid through the ball and a second bore for communicating fluid through the ball. A bore valve is located in the first bore for selectively enabling fluid communication through the first bore

An aircraft includes at least one source collecting a set of navigational parameters of the aircraft, the at least one source obtaining flight data for the aircraft and including at least one of a global positioning system, an inertial reference system, or a sensor. The aircraft further includes a flight control computer communicatively coupled to the source and including a first processor and a first memory having a machine-readable medium, as well as a flight management system communicatively coupled to the flight control computer.

A device for holding a hydraulic cylinder stem in position includes a hydraulic block having series-connected primary and secondary check valves. The latter includes a secondary control stem having a secondary valve body and a seal. A first throttle upstream and a second throttle downstream are closed in a secondary control stem closed position where the seal tightly blocks the secondary check valve, each throttle having a tiny throttle closing gap, preferably 0.1 mm or less. The control stem can move axially into an intermediate position where the throttles remain closed, that is, have a tiny closing gap, but valve body and seal are lifted from a secondary valve seat. The control stem can be moved further into an opening position where the throttles are open, each having an opening gap much larger than the closing gap, and the valve body and seal are lifted from the valve seat.
