The present disclosure is directed toward a suction nozzle operable to remove solid contaminants from a fluid without causing a substantial increase in fluid resistance. The suction nozzle has a vertical flow path, a contaminant precipitation recess opened upward under the vertical flow path, and a lateral flow path extending laterally from the vertical flow path at a position above the contaminant precipitation recess. The fluid sucked from a suction opening in the lower surface is led to the vertical flow path through the lateral flow path and flows upward through the vertical flow path to reach a connection port. With fluid flowing through the vertical flow path, solid contaminants contained in the fluid settle down by gravity and precipitate in the contaminant precipitation recess and are separated and removed from the fluid.

Suction nozzle and fluid recovery apparatus

An electromagnetic compressor capable of reciprocating a piston to suck in and compress a gas by the force of an electromagnet and the resilient force of a return spring and a manufacturing method therefor are provided. The compressor includes a cylinder assembly including a front cylinder portion, a rear cylinder portion, and a center hole capable of storing the piston for reciprocation and having a working chamber defined by means of the piston, and an electromagnet located between the front cylinder portion and the rear cylinder portion and capable of actuating the piston. The cylinder assembly and the electromagnet have an integral structure molded from a resin in a manner such that the internal passage is hermetically sealed with respect to the electromagnet and the electrically conductive member.
