FLUID MEDIUM PUMP, MAINLY FOR MANUAL USE IN INTERNAL COMBUSTION ENGINES OPERATING ON DIESEL FUEL Russian patent published in 2010 - IPC F02M37/16 F02M59/00 

FIELD: engines and pumps.

SUBSTANCE: fluid medium pump intended mainly for manual use in internal combustion engines operating on diesel fuel includes the housing equipped with at least one inlet hole and at least one outlet hole for fluid medium, and a chamber. The latter is attached to inlet hole and outlet hole by means of which a coupling is installed in chamber in a movable way. Fluid medium supply device is connected to housing; at that, there can be established at least one delivery condition in which fluid medium can be supplied by means of supply device and at least one operating condition in which fluid medium flows from inlet hole to outlet hole. In operating condition the first through channel of coupling attaches inlet hole and outlet hole without locking elements. In delivery condition the second through channel of coupling attaches inlet hole and outlet hole in which the second through channel has at least one locking element. By means of coupling between inlet hole and outlet hole there can be made a connection free from locking elements.

EFFECT: possibility of developing a pump through which fuel flows with minimum pressure loss during normal operation of internal combustion engine; at that, fuel pipeline can be pumped easily and simply.
