A rim gasket is coupled to the first end. A cap is coupled to the second end, the cap having a pin passage therethough, the cap having a circumferential concavity on an outer diameter. A valve seat is disposed between the cap and the second end, the valve seat having a second hole that fluidly couples the first opening and the pin passage. A spring is disposed within the first hole. A seal is movably disposed within the first opening and biased against the valve seat by the spring, the seal being movable between a first position and a second position.
A valve assembly, a valve adapter and a bicycle tire are provided. The valve assembly includes a valve stem having a passage. A cap member is fluidly coupled to the passage and has circumferential concavity on an outer diameter adjacent an end. A core body is coupled to the valve stem and has a an axial opening. A biasing member is disposed within the axial opening. A seat is coupled between the core body and the cap member. A first sealing member is movably disposed between a first and second position, the sealing member being biased against the seat by the biasing member, the sealing member having a first end adjacent the seat and a lower portion. A second sealing member is operably coupled to the passage to selectively seal at least a portion of the passage, in response to movement of the lower portion.

PNEUMATIC VALVE SYSTEM AND METHODS OF USING THE SAME
A pneumatic valve for a tire having a stem fluidly coupled to a pressure vessel is provided. The pneumatic valve includes a core body that couples to the stem, the core body having an interior passageway. A cap is coupled to the core body, the cap having a concavity on an outer diameter and a bore hole extending from one end, the bore hole being in selective fluid communication with the interior passageway. The cap further has an interior portion, the core body being at least partially disposed in the interior portion. A valve seat is disposed in the interior portion between the core body and the cap member. A sealing plug is moveably disposed at least partially in the interior passageway and at least partially within the bore hole. A biasing member is disposed in the interior passageway and arranged to bias the sealing plug against the valve seat.
A tubeless tire and a valve for a tubeless bicycle tire having a rim is provided. The valve includes a stem body having a first and second end with a first opening. A rim gasket is coupled to the first end. A cap is coupled to the second end, the cap having a pin passage therethough, the cap having a circumferential concavity on an outer diameter. A valve seat is disposed between the cap and the second end, the valve seat having a second hole that fluidly couples the first opening and the pin passage. A spring is disposed within the first hole. A seal is movably disposed within the first opening and biased against the valve seat by the spring, the seal being movable between a first position and a second position.
A pump-head configured to couple with a bicycle inner tube valve stem or tubeless valve stem is provided. The pump-head includes a housing, inflation pin, a plurality of members and a biasing member. The housing has an attachment member that couples with an air source, the attachment member having an air inlet passage and a collar with a plurality of passages disposed about a periphery of the collar, the plurality of passages extending from an outer diameter of the collar to an inner bore. The inflation pin is coupled to the housing and the air inlet passage, the inflation pin having an end disposed within the inner bore. The members are associated with, and at least partially disposed in, one of the plurality of passages. A biasing member is disposed about the periphery of the plurality of members to biasing each of the members towards the inflation pin.
A pneumatic valve adapter that couples with a valve stem of a bicycle tire is provided. The valve adapter comprises a cap, a seal, a biasing member, and a sealing member. The cap includes a pin passage and a circumferential concavity on an outer diameter. The receiver is coupled to the cap and is couplable with the valve stem, the receiver having a first opening that is fluidly coupled to a central passage. The seal has a circular shape and cross-section, the seal is disposed between the cap and the end of the receiver, the seal having a second hole that fluidly couples the first opening and the pin passage. The biasing member is disposed in the central passage. The sealing member is disposed within the central passage and biased against the seal by the biasing member, the sealing member being movable between a first position and a second position.
An inner tube for a bicycle tire is provided. The inner tube includes a vessel and a valve stem. The valve stem is coupled to the vessel and a end having a fastener, the end having a first opening having a first diameter. A cap is coupled to the fastener and has a pin passage with a second diameter. The cap has a concavity on an outer diameter. A circular seal is disposed between the cap and the second end, the seal having a second hole having a third diameter that fluidly couples the first opening and the pin passage, the third diameter being smaller than the pin passage. A biasing member is disposed within the first hole. A sealing member is movably disposed within the first opening and is biased against the seal by the biasing member.
The present invention provides a pneumatic valve system for easily attaching and sealing a valve coupler to a valve stem for filling an inflatable vessel such as a tire, tube, mattress, etc. The valve system may comprise the following major components: a valve stem, a valve cap with a pin passage and attachment structure for attaching to a valve coupler, a sealing member, a biasing member, the valve coupler comprising a coupler housing, a pin seat, an inflation pin, and a collar with ball bearings complementary to the attachment structure of the valve cap, and an elastic sleeve for providing inward force against the ball bearings. The valve system may allow for easy, secure, and sealed engagement between the valve coupler and valve stem by simply pushing down on the valve coupler, and disengagement by pulling up on the valve coupler with as little as two fingers.
