摘要： A pump for low-viscosity fuel comprises a pump shaft 6 installed in a pump housing 2, 3, 4 and divided into a drive-side shaft 6A and a driven-side shaft 6B, a partition 12 provided between the drive-side shaft and the driven-side shaft of the pump shaft to prevent leakage of fuel from the housing, and a magnetic coupling 13 for transferring torque from the drive-side shaft to the driven-side shaft of the pump shaft through the partition, the magnetic coupling being disposed such that a first clearance C1, D1 between the magnetic coupling and the partition is larger than a second clearance C2, D2 between the magnetic coupling and the pump housing. When wobble occurs in the pump shaft owing to wear of the sliding contact portions thereof, the magnetic coupling makes contact with the pump housing before contacting the partition, thereby enabling the rotation of the pump shaft to be stopped before fuel leakage occurs.

摘要： Herein disclosed a disc type electromagnetic valve which is disposed in the passage of a fluid represented by pressurized gases or air for controlling the flow of the fluid. In a casing at the back of a stator, there is formed a chamber in which a diaphragm is arranged. This diaphragm has its radially inner side connected to either a movable receiver of a spring for biasing an armature apart from the attracting surface of the stator or the armature. The chamber at the back of the diaphragm is caused to communicate with a communication passage of the pressurized fluid through a passage hole which extends through the armature and a valve member. When the pressure of the fluid exerted upon the valve member fluctuates, the diaphragm is moved to automatically adjust the seating force of the valve member against a valve seat.

摘要： An acceleration sensor includes a body supporting a casing within which a magnetic member is received. A plurality of magnets are mounted on the body and disposed around the casing. The magnetic forces of the magnets hold the magnetic member in a reference position within the casing. The magnetic member is displaceable from the reference position against the magnetic forces of the magnets when the acceleration sensor is subjected to acceleration. A detection device is mounted externally of the casing so as to detect displacement of the magnetic member from the reference position. The acceleration sensor further includes a position adjusting device for adjusting the position of at least one of the magnets relative to the casing so as to set the intensities of the magnetic fields of the magnets in predetermined relation within the casing.
