A breather cap assembly configured to be connected to a stand-tube used in a watering system. When the watering system is in normal operation, the breather cap assembly is configured to allow for air to flow between the outside the assembly and the stand-tube. The breather cap assembly also provides for structure which acts as a baffle to minimize the introduction of foreign material from outside the breather cap assembly into the stand-tube. When the watering system is in flushing operation, the breather cap assembly is configured to seal off the stand-tube in order to minimize the possibility of water leaving the stand-tube. The breather cap assembly further also provides for structure which acts as a baffle to collect and retain a majority of any water that does leave the stand-tube during a flushing operation.

A liquid capture valve may have a housing that physically contacts a lid and contains a floating member. The lid can have an inlet and an outlet with the outlet positioned at an apex of a sealing surface. The floating member can be configured to seal the outlet by contacting an outlet edge in response to the housing containing a predetermined volume of liquid.

An air removal assembly can include an air valve mountable on a fluid system; and a throttling device in fluid communication with the air valve, the throttle device further in fluid communication with the fluid system through the air valve when the air valve is mounted on the fluid system, the throttling device including: a body having an inner and outer surface, the inner surface defining a body cavity, the inner and outer surfaces defining a plurality of body orifices in fluid communication through the body cavity; a throttle movably positioned within the body cavity proximate to a first orifice of the plurality of orifices, the throttle movable to a closed position closing the first orifice and to an open position opening a fluid pathway between the first orifice and the body cavity; and a biasing element biasing the throttle to a partially-open position between the closed and open positions.

An air induction system for filtering a compressible fluid to an electromechanical component mounted on a wheel of a vehicle. The system may make use of a first plurality of float valves arranged in series in a non-linear first flowpath path, with at least one of the float valves forming an inlet for intaking the compressible fluid into the first flowpath, and one being in communication with an inlet of the electromechanical component. Each of the float valves may have a buoyant float valve element therein which is responsive to change position when submerged in water, to close off its respective float valve depending on an angular orientation of the wheel, and thus an angular orientation of the float valve.

In one aspect the present disclosure relates to an in-wheel tire pressure system for use with a rim of a wheel of a vehicle. The system may comprise a fluid storage area formed in the rim for holding a quantity of compressible fluid suitable for inflating a tire mounted on the rim, and a micro-compressor mounted on the rim for pressurizing the fluid storage area with the compressible fluid. A wireless electrical charging subsystem may also be included for powering the micro-compressor. The wireless electrical charging system may incorporate a first component associated with the rim and rotatable with the rim, and a second component fixedly mounted to a portion of the vehicle closely adjacent the first component. The system may also include a control for enabling user control over the micro-compressor.

The invention discloses an air vent valve for venting a filter, having a cavity with an inlet and an outlet and a sealing element in the interior of the cavity for sealing the inlet in a first position and for sealing the outlet in a second position. The sealing element is freely movable between the first position and the second position, and a flow is created between the inlet and the outlet when the sealing element is in an intermediate position between the first position and the second position.

An air removal assembly can include an air valve mountable on a fluid system; and a throttling device in fluid communication with the air valve, the throttle device further in fluid communication with the fluid system through the air valve when the air valve is mounted on the fluid system, the throttling device including: a body having an inner and outer surface, the inner surface defining a body cavity, the inner and outer surfaces defining a plurality of body orifices in fluid communication through the body cavity; a throttle movably positioned within the body cavity proximate to a first orifice of the plurality of orifices, the throttle movable to a closed position closing the first orifice and to an open position opening a fluid pathway between the first orifice and the body cavity; and a biasing element biasing the throttle to a partially-open position between the closed and open positions.

A water hammer-proof air valve that has a valve body and a bonnet, that are fixedly connected, a valve opening is provided on the valve body, and a high-speed intake and exhaust device is provided in an inner cavity of the valve body. A bonnet opening is provided on the bonnet, an output end of the high-speed intake and exhaust device penetrates the bonnet opening and is communicated with a high-speed exhaust throttling device for limiting an exhaust amount of gas of the high-speed intake and exhaust device, an output end of the high-speed exhaust throttling device is communicated with an outside air, and a trace exhaust device for discharging the gas separated out from the pipeline to the outside through the high-speed exhaust throttling device after the high-speed intake and exhaust device closes the valve is further provided in the high-speed intake and exhaust device.

A vent apparatus is described for providing filtered air intake and rollover protection for a fuel tank. The apparatus may include a housing configured to be coupled with the fuel tank, the housing including at least one air intake port and at least one air exhaust port. The apparatus may include an air intake filter disposed within the housing and configured to receive and filter air from the at least one air intake port. The apparatus may include a rollover protection valve disposed adjacent to the housing and configured to be located inside the fuel tank when the housing is coupled with the fuel tank, the rollover protection valve coupled with the at least one air exhaust port. The rollover protection valve may include a chamber and a plug configured to impede the flow of fuel from the fuel tank into the at least one air exhaust port.

A throttling device comprising: a body having an inner surface and an outer surface, the inner surface defining a body cavity, the inner surface and the outer surface defining a plurality of body orifices in fluid communication through the body cavity; a throttle movably positioned within the body cavity proximate to a first orifice of the plurality of body orifices, the throttle movable to a closed position closing the first orifice and to an open position opening a fluid pathway between the first orifice and the body cavity; and a biasing element biasing the throttle to a partially-open position between the closed position and the open position.
