An air pump device includes an air generating mechanism, an air tube unit, an air cylinder, and a control mechanism. The air cylinder has an air-receiving space and an air channel being in fluid communication, and a valve unit. The control mechanism includes a manifold seat interconnecting a linking unit of the air generating mechanism and the air tube unit, and a control unit convertible between an air-storing position, where air advanced from the linking unit into the manifold seat is limited to flow into the air channel, and the valve unit is opened to allow entrance of the air into the air-receiving space, and an air-pumping position, where air advanced from the linking unit into the manifold seat is limited to flow into the air tube unit.

A tire chuck adaptor is an apparatus that allows a single user to easily fill a motorcycle tire with air. The tire chuck adaptor includes a sleeve, an extension coupler, an orientation coupler, an air chuck, a valve, a bearing, and a chuck receiving window. The sleeve contains the extension coupler, the orientation coupler, the valve, and the bearing. The valve allows a standard tire chuck to be engaged to the tire chuck adaptor. The bearing allows the valve to rotate within the sleeve. The extension coupler extends the connection between the valve and the standard tire chuck. The orientation coupler changes the connection orientation between the valve and the standard tire chuck. The air chuck allows the tire chuck adaptor to engage with a standard tire valve. The chuck receiving window allows a user to access the valve to engage with a standard tire chuck.

A pump head includes a casing unit, a tightening member and a control unit. The casing unit includes a main body and an abutment wall connected to the main body. The main body has an installation section. The tightening member is disposed in the installation section proximally to the abutment wall. The control unit includes a control valve, a resilient member and a control lever. The control valve is movably disposed in the installation section. The resilient member urges the control valve toward the abutment wall to clamp the tightening member between the control valve and the abutment wall. The control lever is connected to the main body and operable to move the control valve against the resilient member and away from the abutment wall.

A dual-air tap inflation nozzle includes a body, a first cap assembly, a second cap assembly, a slidable valve slidably disposed in the body, and a lever member. The body has a first end, a second end, a first passage and a second passage in communication to the first passage. The first cap assembly is mounted to the first end and has a third diameter. The second cap assembly is mounted to the second end and has a fourth diameter larger than the third diameter. The lever member is abutable against the slidable valve to cause the second passage to move in relation to the first passage. Thus, the second passage is in communication with a first inflatable space or a second inflatable space of the body.

The present disclosure generally relates to a manifold valve assembly engaged to an inflatable apparatus, such as a cushion to prevent pressure ulcers, for example. The manifold valve assembly is also in communication with a processing device to determine an optimal immersion level for a user seated on the inflatable apparatus. Additionally the processing device, in communication with the manifold valve assembly may save optimal immersion or air pressure levels for comparison to future checks of cushion pressure and send that to a user interface at the processing device. The assembly and processing device may also save and display a history of pressure checks.

A system includes a client application executed by a client computing device for setting up an inflation level and checking an inflation level of an inflatable cushion having at least one air cell or zone and at least one pressure sensor within the cushion that detects air pressure. The client computing device communicates with the inflatable cushion and determines an optimal inflation level for a user of the inflatable cushion.

A valve connector for a high pressure air pump includes an outer sleeve having opposite first and second ends. The outer sleeve includes a coupling hole extending along a rotating axis and a receiving space intercommunicating with the coupling hole and located adjacent to the first end of the outer sleeve. An abutting member includes an abutting end received in the receiving space and a connecting end opposite to the abutting end. The abutting member includes an inlet passageway intercommunicating with the abutting end and the connecting end. An outer periphery of an airtight member about the rotating axis slidably abuts and is in airtight contact with an inner periphery of the receiving space. The airtight member is movable toward the first end or the second end. The airtight end face is configured to be biased toward the first end by air current entering from the inlet passageway.

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 chuck for inflating a tire having a valve includes a valve engagement device having a longitudinal axis, a first portion and a second portion that move laterally with respect to the longitudinal axis and in parallel with each other to define a chamber for receiving the valve stem. An actuator that moves longitudinally with respect to the valve engagement device causes the first portion and the second portion to move laterally and in parallel. The first portion and the second portion of the valve engagement device include protrusions, and the actuator contacts the protrusions as the actuator is moved longitudinally.

A push-to-press inflation adaptor is provided for use with an English valve and includes a valve connector, a connection barrel, a coupler, an air tube, and a spring. The valve connector includes a first movement hole, a positioning cavity, a communication compartment, a valve opening and a constraint opening. The connection barrel is coupled to the valve connector. The connection barrel includes a second movement hole and an air tube opening. The coupler is received in the first movement hole and the second movement hole of the valve connector and the connection barrel and is reciprocally movable through application of a force thereto. The air tube is received through the air tube opening into the connection barrel to be jointed to the coupler. The spring is supported between the coupler and the connection barrel to provide a preloading force to bias the coupler in a direction toward the constraint opening.
