摘要： A check valve for preventing water hammer in which a valve element is adapted for quick initiation of a valve closing motion without delay in response to an abrupt change in fluid flow resulting from stoppage of a pump, and which is seated on a valve seat when the inertial flow of the fluid in the discharge direction stops, without generating a water hammer and impulse noise. The valve element and the valve seat are constructed so that the valve element follows the motion of the flowing fluid and is interlocked with a braking device by a linear motion transmitting mechanism. The linear motion transmitting mechanism and the braking device are constructed to remove the effect of braking actions that decelerate the valve closing motion of the valve element and of frictional resistance in the period between when the valve element starts a valve closing motion and when the valve element is almost seated on the valve seat, and then to brake the valve element gently only until the valve element is seated on the valve seat. The timing of the seating of the valve element on the valve seat can be adjusted by a mechanism for adjusting the braking action starting position, by a bypass adjusting valve combined with the braking device or by a mechanism for adjusting biasing force applied to the valve element.

摘要： A bidirectional clutch for a pulley drive has a rotary cam adapted to be mounted on an upright drive shaft of a motor, a pulley body having a drum portion coaxial with and spaced from the rotary cam, a plurality of rotary bodies positioned in the space between the drum portion and the rotary cam, and a guide member for rotatably supporting the rotary bodies for movement toward and away from the drum portion, a face of the rotary cam being opposed to the drum portion having a cam portion which, upon the cam being rotated relative to the rotary bodies and the drum portion through an angle equal to or greater than a predetermined angle, moves the rotary bodies toward and pressed them into engagement with the drum portion to transmit the rotational force of the motor to the drum portion and the pulley body.
