A deflation apparatus includes a cylindrical deflation main body including a socket portion and an exhausting portion. The socket portion includes an opening for receiving a spool of a valve and the opening is connected to an inner space, being through the socket portion and the exhausting portion, and an outer wall of the exhausting portion includes a plurality of exhausting holes connected to the inner space. An exhausting direction of the exhausting holes is orthogonal to the longitudinal axis of the deflation main body. A flat stream leading portion, in the inner space, is configured to separate the inner space to form at least two exhausting channels. Each of the exhausting channels is connected to at least one of the exhausting holes. The flat stream leading portion has an abut side, wherein the abut side is extended toward the opening and abuts the spool of the valve.

An O-ring membrane valve, including an O-ring, and a resealable membrane connected to the O-ring, the resealable membrane including a first surface, a second surface, and a slit extending from the first surface to the second surface. The O-ring membrane valve may be assembled with a fluid connector, the fluid connector including a body, having a first through-bore and a first groove arranged circumferentially within the first through-bore.

A Presta valve connector includes a housing and a stripping assembly rotatably connected to the housing. The housing is provided with a channel and an airtight ring having a connection hole. The airtight ring and the stripping assembly are disposed at two opposite ends of the channel. One end of the stripping assembly is disposed in the channel, and another end of the stripping assembly is exposed out of the channel. One end of the stripping assembly is provided with a driving groove faced to the connection hole. The driving groove is provided with a first driving face formed as a plane.

A first tubular and a second tubular define a fluid passage. A feather is positioned within the first tubular. The feather is configured to axially translate towards the second tubular and pivot towards a center of the first tubular. The feather includes a hinge on a pivoting end. A first end of a spring is coupled to the feather and a second end of the spring is coupled to the first tubular. The spring is loaded to actuate a movement of the feather between an open position and a closed position. A trigger is positioned between the first tubular and the second tubular to provide an interference with the feather. The interference retains the feather in the open position when the first tubular and second tubular are coupled.

A coupler for connecting to a port, and a method for connecting a coupler to a port are provided. The coupler includes a body, a plunger needle, and a threaded portion. The body includes a radially outward facing surface, a radially inward facing surface, a proximal end, and a distal end. The plunger needle is fixed to the body, and extends in parallel with the body toward the distal end of the body. The threaded portion extends circumferentially around at least a portion of the radially outward facing surface of the body toward the distal end of the body, the threaded portion configured to receive a threaded portion of the port.

A normally closed port valve seals a hydraulic hose connection port of a hydraulic bicycle component. Connection of an end of a hydraulic hose assembly to the port opens the valve, placing the assembly's hydraulic fluid chamber in fluid communication with the interior of the hose assembly. A hydraulic cylinder of the assembly is in fluid communication with the chamber. A spring may be used to bias the valve to a closed condition.

A docking device for mechanically connecting an upper container module of a multipart container for a fluid and a lower container module of the multipart container. The docking device includes an upper docking segment, which is fastenable using an upper connecting means on opening of the upper container module, and a lower docking segment, which is fastenable using a lower connecting means on an opening of the lower container module so that fluid moves from the upper container module through a channel of the docking device into the lower container module, or moves due to buoyancy and/or due to pressure from the lower into the upper container module, if at least one valve body movable by means of an actuating assembly is in an open valve body position. An upper channel section is arranged in the upper docking segment and a lower channel section is arranged in the lower docking segment. The actuating assembly is actuatable so that it is movable from an open valve body position into a closed valve body position or from a closed valve body position into an open valve body position. The actuating assembly includes at least one blocking assembly comprising at least one blocking means that is moved into a blocking position during the docking process
