Abstract: A control valve is provided, comprising a valve body having an inlet port extending along an inlet axis, first and second outlet ports extending along outlet axes substantially parallel to a single reference axis and substantially perpendicular to the inlet axis, first and second sealing ports associated, respectively, with the first and second outlet ports and each disposed in a fluid path between the inlet port and its respective outlet port, and first and second sealing members configured for independently and selectively opening and closing the first and second sealing ports, respectively. Each of the sealing ports extends along a sealing axis extending transverse to a plane being parallel to its respective outlet axis and the inlet axis, and forms, between a downstream end thereof and an upstream end of the inlet axis, an obtuse angle greater than 90°.

Abstract: A gastrointestinal device including a casing including fixation elements adapted for intraluminal fixation of the device in a gastrointestinal tract (e.g., the anorectal wall), a valve disposed in the casing and controllable to move from a closed position, which significantly restricts passage of gastrointestinal (e.g., fecal) matter therepast, and an open position, which permits passage of gastrointestinal matter therepast, and a controller operatively connected to the valve for externally controlling the position of the valve between the closed and open positions.

Abstract: A gas purge valve comprising a housing fitted with an inlet port being in flow communication with a liquid outlet port, and at least one gas outlet member, a gas flow barrier associated with the liquid outlet port, a float member displaceable within the housing between a first position adjacent the inlet port and a second position adjacent the gas outlet The at least one gas outlet is fitted with an inlet prohibiting valve, and is sealingly engageable by a flexible sealing member articulated to the float member. Buoyant displacement of the float member into the second position entails sealing of the at least one gas outlet by the flexible sealing member.

Abstract: A hydraulic diaphragm valve comprising a housing, an inlet, an outlet, a diaphragm valve seating between the inlet and the outlet, a sealing diaphragm mounted in the housing and displaceable about the diaphragm valve seating, so as to close and open a flow path between the inlet and outlet, a valve control chamber and a command valve comprising a first duct communicating a one end thereof with the valve inlet, and at an opposite end thereof with a first command valve seating, a second duct communicating into one end with the valve outlet, and at an opposite end thereof, with a second command valve seating. A third duct communicates at one end with the valve control chamber and at its opposite end it selectively communicates with the first and second command valve seatings.
