Abstract: 1,232,366. Valves. J. E. NORFORT. 24 March, 1970, No. 14239/70. Heading F2V. [Also in Division F4] A thermostatically controlled radiator valve for a hot water central heating system comprises a valve member 8 axially displaced by a bellows 9 to reduce the water flow aperture past a seat 7 consequent upon ambient temperature conditions, the member 8 having an axially movable throttling member 19 projecting downwardly therefrom against a spring 10 under the control of an axially movable and spring urged head 11 in a sleeve 12. A known locking device (not shown) is mounted between the head and sleeve (in the manner of a ball point pen) to lock the head after a predetermined downward movement and to release the head after subsequent depression occasioned by pressure surges in the water flow. An adjustable screw 14 abutting the head adjusts the point at which locking occurs and the screw is mounted in a sealing bellows 15. In operation, a first pressure surge moves the valve 8 upwardly to extend the bellows 9 and the head and throttling member move downwardly relative to the valve to be locked in the outwardly projecting position and remain there when the pressure returns to normal and the valve 8 moves to a position determined by the bellows 9. A further pressure surge again moves the valve to unlock the throttling member.

The first drive comprises a bell crank 19 actuated by the body 8 of the plunger so that an arm (23) (Fig. 5, not shown) can move a rod (24) via springs (29), (30) to rotate a shaft (34) and hence a lever (35) (Fig. 1, not shown). The springs (29), (30) provide the lost motion to allow continuing movement of the plunger 9 and bell crank 19 after the lever (35) has rotated fully to move the clamping member 5 from the withdrawn to the operative position. The member 5 slides by means of slots 13 on a T-shaped support member 4 which is pivoted about a shaft 3. During the sliding of the clamping member 5 a cross pin 37 in the plunger moves along a groove 38 without applying a pivoting force to the clamping member 5. The second mechanical drive comprises a direct abutment of a part 18 of the plunger 9 with the underside of the clamping member 5 when it reaches the operative position to pivot the clamping member about shaft 3 to clamp a workpiece. The groove 38 and pin 37 provide a lost motion connection during the rectilinear sliding of the clamping member 5. The springs (29), (30) return the clamping member from the clamping position to the withdrawn position in the correct sequence after release of pressure fluid from passage 10. In alternative arrangements the clamping member may be pivotally mounted on a block slidable on the base; both movements of the clamping member are rectilinear; the second direct abutment drive may be used to effect the first rectilinear movement; and the lost motion may be provided by a sprocket having a toothless portion.
