FIELD: engines and pumps.
SUBSTANCE: drive represents a linear motor with cylindrical housing provided with end plug to house stator and reciprocating head. Said reciprocating head consists of a hollows shaft with radial holes supporting permanent magnets and magnetic cores. Chambers formed inside said housing and separated by stator and reciprocating head are communicated via hollow shaft. Note here that, at least, one of said chambers communicates with annular space via filter.
EFFECT: longer life, higher reliability in operation with major amount of mechanical impurities.
