Abstract:
1. An electromagnetic valve device to be incorporated in pressure equipment using a pressure fluid with a portion thereof exposed from the pressure equipment, the electromagnetic valve device comprising: a housing formed with a primary port and a secondary port which are connected to each other through a valve path; a displaceable valve configured to vary an opening of said valve path by displacement thereof; electromagnetic drive means operative to drive said valve for displacement by a magnetic action caused by utilization of electric power; and electric conductor means for supplying electric power to said electromagnetic drive means, said electric conductor means being held by said housing so as to extend inside said housing from the portion of said housing that is exposed from the pressure equipment to another portion of said housing that accommodates said electromagnetic drive means therein, wherein: said housing comprises a plurality of housing sections joined together, the plurality of housing sections arranged to be joinable to one another by moving the housing sections in a predetermined direction parallel to an axis; said electric conductor means comprises electric conductor pieces connected to each other, each of which is held by a respective one of said housing sections; said electric conductor pieces are connected to each other with an operation of joining said housing sections together; wherein said electric conductor pieces include a first electric conductor piece having a pin-shaped end portion and a second electric conductor piece having a socket-shaped end portion, said pin-shaped end portion being caught resiliently by said socket-shaped end portion when said pin-shaped end portion is inserted into said socket-shaped end portion, the first electrical conductor piece extending from a first one of the housing sections in a linear direction parallel to the axis, the second electrical conductor piece mounted to a second one of the housing sections such that the pin-shaped end portion of the first conductor piece is insertable into the socket-shaped end portion of the second conductor piece along the predetermined direction and parallel to the axis; wherein the second electric conductor piece includes a flange portion; a seal means disposed in the housing and operatively engaged by the flange portion, the seal means disposed toward a low pressure side of the valve device relative to the flange portion; and wherein the first electric conductor piece includes a connecting portion connected to the electromagnetic drive means, and including a filling material filled around the connecting portion to protect the connecting portion.
