An oil storage and filtration system for an engine unit includes an on/off valve that defines an operating phase when receiving supply air and in an on position and a standby phase when in an off position or not receiving the supply air. The system also includes a fill/drain valve that defines a drain state and a fill state which respectively correspond to emptying and filling oil from/into the engine unit. The system also includes a control valve, a pressure/vacuum valve, and a storage tank. The storage tank stores oil in a pressurized condition during the fill state, a vacuum condition during the drain state, and an atmospheric condition during the standby phase. The also includes a vacuum generator in fluid communication with the storage tank during the drain state and fluidly isolated from the storage tank during the fill state.

The present invention pertains in general to an apparatus and method for the drying and activating of infusing material, and the infusing, agitation and dispensation of oils in a controlled manner to produce a desired potency of an infusion while remaining below an identified maximum temperature threshold.

A filter pulsation dampening device has a replaceable filter element including a plurality of baffles disposed next to each other or a flexible valve that is disposed proximate a baffle.

A “no filter, no run” filtration system that is designed to verify that a filter cartridge is present to safe-guard against damage to fuel injectors, associated fuel components, etc. and engine malfunctions. Fuel flow to the engine is prevented altogether or permitted in an amount insufficient to allow engine operation if a filter cartridge is not installed, and an appropriately designed filter cartridge is required to be used in order to permit sufficient fuel flow for engine operation. In one embodiment, a flow restriction valve is provided that includes a ball.

A water purifier includes a filtering part including a reverse osmosis filter for filtering water and a discharge part for discharging, to the outside, purified water filtered in the filtering part. The filtering part further includes a pump provided in front of the reverse osmosis filter so as to supply the water to the reverse osmosis filter, and a supply valve that opens and closes so as to supply the water from a water supply source to the filtering part. The supply valve can be provided between the pump and the reverse osmosis filter.

A transport device includes a transporting belt having a support face configured to support a medium and configured to transport the medium, a device main body in which the transporting belt is provided, and a cleaning unit configured to clean the support face with a liquid. The cleaning unit includes a storage unit in which the liquid is stored, a flow path member through which the liquid discharged from the storage unit and returned to the storage unit passes, and a filter unit detachably provided to the flow path member. Here, the filter unit is configured to be pulled out in a direction away from the device main body.

A filter cap includes a first end and a second end facing away from the first end. A first cylindrical projection projects from the first end of the filter cap and a second cylindrical projection projects from the second end. An annular recess is formed around the first cylindrical projection. The second cylindrical projection includes at least one peripheral groove for an O-ring and a plurality of radially inward extending ridges. A passageway extends through the first and second projections. The passageway has a first dimension in the first projection, a second dimension greater than the first dimension in the second projection near a distal end of the second projection, and a third dimension smaller than the second dimension within the second projection between the plurality of ridges.
