A gas control unit for a boiler is provided which can satisfactorily control the supply and shut-off of gas. The gas control unit for a boiler includes: a hollow housing; a solenoid that is disposed in the housing; a rod that is inserted into the solenoid and that has a lower part protruding from the housing; opening and shutting means that is disposed at the lower end of the rod so as to open and shut a gas outlet; and a spring that is disposed between the housing and the opening and shutting means so as to elastically urge the opening and shutting means downward. Here, a coupling member is formed at the lower end of the rod and a coupling groove into which the coupling member is inserted is formed in the opening and shutting means so as to allow the opening and shutting means to move. Accordingly, since the opening and shutting means is coupled to the rod through the use of the coupling member and the coupling groove, the opening and shutting means can move within a predetermined range about the coupling member with an application of an external force. Therefore, even when the opening and shutting means and the gas outlet depart in center from each other, it is possible to shut the gas outlet, thereby satisfactorily controlling the supply and shut-off of gas.
Disclosed herein is a gas control apparatus for a boiler, which has a simple structure and enables easy assembly, thus improving productivity and reducing manufacturing costs, therefore enhancing the competitiveness of a product. The gas control apparatus includes a solenoid retracting or ejecting a rod in response to application of power. A cylindrical support unit is coupled to an upper portion of the solenoid and has a suction port and an exhaust port on a side surface and an upper surface thereof, respectively, with a groove being formed along a lower edge of the support unit. A separator is provided between the solenoid and the support unit in such a way that an edge thereof is inserted into the groove. An opening and shutting plate is mounted to an upper end of the rod and opens and shuts the exhaust port of the support unit.
Disclosed is a solenoid valve which can minimize foreign materials included in fluid of a valve which flows in a solenoid. The solenoid valve includes a solenoid, a valve operated by the solenoid, and a plate filter disposed between the solenoid and the valve. The valve includes a hollow holder having one or more chambers and ports formed therein, and a spool reciprocating upwards and downwards within the holder by the solenoid. In addition, the plate filter includes an outer ring fixed to the holder, an inner ring fixed to the spool, and a filter membrane formed between the outer ring and the inner ring. The plate filter is disposed between the solenoid and the valve so that foreign matter included in the fluid flowing into the solenoid can be minimized. When a through-hole is formed in the solenoid and a column filter is provided to the solenoid, operational resistance due to change in internal pressure of the solenoid can be reduced and heat can be discharged from the solenoid to the outside during movement of a plunger.

Disclosed is a solenoid valve for controlling a high flow rate for direct shift control of an automatic transmission. The solenoid valve includes a holder (110) having inlet and outlet ports (111,112), a residual pressure relief-discharge port (113) and a passageway (114), a spool (120) located in the passageway (114) of the holder (110), a rod (130) closely contacting the spool (120), a plunger (140) surrounding the rod (130), a bobbin (150) surrounding the plunger (140) and having a coil (151 ), a yoke (160) between the bobbin (150) and the holder (110), a core (170), and a case (180). The valve removes resistance to fluid discharge from a chamber (171 ) during plunger movement to enhance responsiveness of a controlled pressure, and allows a fluid to flow into a plunger actuator, thereby suppressing a temperature increase by the coil (151 ) while ensuring a damping function in the plunger actuator.
A control device for a clutch drive shaft for 2-wheel/4-wheel drive conversion in a vehicle is disclosed.

The first plate and the second plate are coupled by detent-fastening the detent protrusions of the coupling parts on the detent ledges of the coupling holes. Also, a shock absorber member made of a rubber material is additionally included, coupled to the second plate of the upper plate. A through-hole having a securing ledge can be formed in a center of rotation of the second plate, and a securing part having a securing protrusion can be formed on a center of rotation of the shock absorber member, so that the securing protrusion of the securing part may be detent-fastened on the securing ledge of the through-hole.
