30results about How to "Reduces clogged filters" patented technology

An ECU reduces a fuel flow rate discharged from an electric pump to the filter when a fuel temperature and a fuel pressure in the filter detected by a sensor portion drop. Since a mechanical pump continues to be driven without respect to the fuel quantity discharged from the electric pumps when the fuel flow rate discharged from the electric pump is decreased, a suction pressure is generated at an inlet of the filter. The fuel in a recirculation passage is introduced into the filter through a branch passage. As the result, relatively high temperature fuel is introduced into the filter to melt a solidified fuel causing a clogging of the filter.

A novel decoction device for Chinese herbal medicines comprises a tank, a filter screen, a lower cover, a lock ring, open-cover cylinders and an open-ring cylinder, wherein the filter screen is arranged at the lower part in the tank; the lower cover is arranged at the lower end of the tank; the lock ring is arranged on an excircle at a joint of the lower cover and the tank; the open-cover cylinders are vertically and symmetrically arranged on two sides of the tank, upper parts of the open-cover cylinders are connected with two sides of the tank, and lower ends of the open-cover cylinders are connected with two sides of the lower cover; the open-ring cylinder is horizontally arranged at the lower part of the front of the tank, one end of the open-ring cylinder is connected with the tank, and the other end of the open-ring cylinder is connected with the upper surface of the lock ring. With adoption of the technical scheme, good effects are realized; filter screen blockage is reduced effectively by the novel filter screen at the lower part of the novel decoction device for the Chinese herbal medicines, the filter screen is convenient to replace, decoction dregs are dumped quite conveniently, splash of the decoction dregs during taking is avoided, overall use is more convenient and faster, and convenience and benefits are brought to an enterprise.

This invention relates to image formation toner, 2-component developer, image formation method and method for manufacturing image formation toner, for preventing clogging of the filter. Toner is used in which the ratio of the component measured by GPC to have a molecular weight between 500 to 1000 is 10 parts by weight or less with respect to 100 parts by weight of the entire toner. Since the case of clogging of the HEPA filter is the 500 to 1000 molecular weight component, clogging of the filter is prevented by reducing this component.
