The invention relates to a controllable valve, particularly for delivering a pulsed flow of fluid. It comprises a valve body (10); a valve seat (12) dividing the inside of the body into an inlet chamber (14) and an outlet chamber (16); a valve shutter element (22) capable of moving; an actuator (24)
The invention relates to a controllable valve, particularly for delivering a pulsed flow of fluid. It comprises a valve body (10); a valve seat (12) dividing the inside of the body into an inlet chamber (14) and an outlet chamber (16); a valve shutter element (22) capable of moving; an actuator (24) comprising a stationary control part (26) for receiving control signals and a moving part (28); first rigid means of connection (30) for connecting the said moving part of the actuator (28) to the said shutter element (22); a mechanical stop (40'); a member (38) that can be compressed under the effect of a force applied to it, comprising a first end secured to the said mechanical stop; and second rigid means (36') for dynamically connecting one of the faces of the said shutter element (22b) to the second end of the said compressible member (38).

The assembly of claim 1, wherein said retainers at each side wall are off set vertically and said shelf in its other operative position resting upon said offset retainers with its said first wall part being supported by the uppermost off set retainer and its said second wall part being supported by the lowermost offset retainer. 4. The assembly of claim 1 wherein said frame includes a bottom wall, said sidewalls extending upwardly from said bottom wall, and a removable back wall extending between said sidewalls. 5. The assembly of claim 1 and wheels supporting said frame. 6. The assembly of claim 1, wherein each said shelf is inverted when in its said another operative position in relation to its said first operative position. 7. A convertible shelving unit having adaptable shelves, said shelving unit comprising a frame including two sidewalls, each shelf including two wall parts, each of said wall parts having first and second end edges, said first wall part being joined at its said first edge to said first end edge of second wall part forming with said wall part a general right angle to each other, said second wall part of each shelf including a catch part at its said second end edge, each of said frame sidewalls carrying laterally spaced retainers, each retainer being selectively locatable at a plurality of vertically spaced locations along the supporting sidewalls, each shelf having three positions carried by said retainers including: a first position in which said retainers are horizontally aligned, said first wall part carried horizontally by said retainers; a second position in which said retainers are horizontally aligned, said shelf supportively positioned inverted from said first position, said first and second wall parts carried by said retainers to position said shelf in a cradle supportive position, said catch overlying one of said retainers; and a third position in which said retainers at each side wall are off set vertically, said shelf supportively positioned, its said first wall part supported by each uppermost retainer, its said second wall part supported by each lowermost retainer, said catch overlying said lowermost offset retainer. control valve according to claim 1, wherein said malfunction detecting means detects malfunction of said water temperature control valve based on a deviation of the value of the temperature of said cooling water detected by said cooling water temperature detecting means from the target value of the temperature of said cooling water set by said target temperature setting means. 3. The malfunction detecting apparatus for a water temperature control valve according to claim 1, wherein said malfunction detecting means detects malfunction of said water temperature control valve when a deviation of the value of the temperature of said cooling water detected by said cooling water temperature detecting means from the target value of the temperature of said cooling water set by said target temperature setting means exceeds a certain judgment threshold value for at least a certain time period. 4. The malfunction detecting apparatus for a water temperature control valve according to claim 3, further comprising: means for detecting an operating state of said internal combustion engine wherein said certain judgment threshold value is set variably based on the operating state of said internal combustion engine detected by said operating state detecting means. 5. The malfunction detecting apparatus for a water temperature control valve according to claim 4, wherein: said cooling water temperature detecting means includes a sensor provided to a cooling water passage of said internal combustion engine for outputting the temperature of said cooling water, and detecting the temperature output from said sensor; and said cooling water temperature controlling means adjusts said water temperature control valve in such a manner that the temperature of said cooling water detected by said cooling water temperature detecting means follows the target value of the temperature of said cooling water set by said target temperature setting means. 6. The malfunction detecting apparatus for a water temperature control valve according to claim 5, wherein said sensor is provided at a position along a passage from a junction of said radiator passage and said bypass passage to said internal combustion engine. 7. The malfunction detecting apparatus for a water temperature control valve according to claim 1, wherein: said cooling water temperature detecting means includes a sensor provided to a cooling water passage of said internal combustion engine for outputting the temperature of said cooling water, and detecting the temperature output from said sensor; and said cooling water temperature controlling means adjusts said water temperature control valve in such a manner that the temperature of said cooling water detected by said cooling water temperature detecting means follows the target value of the temperature of said cooling water set by said target temperature setting means.
