A cooling unit is provided for use with a cooling system of an internal combustion engine. The cooling system includes an air-cooled radiator to reject heat from a coolant of the internal combustion engine. The cooling unit comprises an air-cooled heat exchanger to reject heat from another medium to an air flow, an air receiver and at least one releasable clamp. The heat exchanger includes an inlet for the air flow, an outlet for the air flow, and an outer perimeter extending between the inlet and the outlet. The air receiver is connectable to the radiator and surrounds the outer perimeter of the heat exchanger. The air receiver includes an inlet end for the air flow, an outlet end for the air flow, and an air duct extending between the inlet end and the outlet end to direct the air flow from the outlet of the heat exchanger to the outlet end of the air receiver. The inlet end and the inlet are substantially coplanar. The clamp is engaged with the air receiver to tighten the air receiver against the heat exchanger.

A damper valve as claimed in claim 1, wherein the check valve is of a unit assembled from a case fixed in the valve sleeve, a movable valve body accommodated in the case, and a valve seat member mounted in the case for allowing the movable valve body to be seated thereon. 3. A damper valve as claimed in claim 1, wherein the check valve includes a ball for closing an interior of the valve sleeve, and a lock plate serving to retain the ball within the valve sleeve and having a through hole allowing the hydraulic oil to flow therethrough. 4. A hydraulic power steering device comprising: an oil-hydraulic pump; a hydraulic actuator operated by a hydraulic oil supplied by the oil-hydraulic pump thereby outputting a steering assist force; an oil-pressure control valve disposed on an oil-hydraulic circuit at place between the hydraulic actuator and the oil-hydraulic pump and operative to control the supply/discharge of the hydraulic oil to/from the hydraulic actuator according to a steering operation; and the damper valve claimed in any one of claims 1 to 3 and disposed on the oil-hydraulic circuit at place between an output port of the oil-pressure control valve and the hydraulic actuator. hereof and by which a positive pressure of at least a predetermined amount may be maintained in said tubular rod while said containers are being filled with liquid through said lance. 5. Apparatus for filling containers with liquid, as set forth in claim 4, in which said supply of low pressure gas is an inert gas. 6. Apparatus for filling containers with liquid, as set forth in claim 4, in which said supply of low pressure gas is air. 7. Apparatus for filling containers with liquid, as set forth in claim 4, in which the pressure of said low pressure gas is less than 2 psi. 8. Apparatus for filling containers with liquid, as set forth in claim 1, in which the lower end of said lance is provided, on the interior thereof, with a central guide which surrounds said tubular rod to keep said foot valve centered in its movement between said closed and open positions. 9. Apparatus for filling containers with liquid, as set forth in claim 1, in which said foot valve comprises an upwardly and inwardly tapered guide surface and a surrounding seal engageable with a corresponding surface on the lower end of said lance, when said valve is in said closed position, to prevent flow of fluids through said lance. 10. A method of filling a container with liquid with apparatus which includes a filling lance operatively connected to a source of liquid and to power means by which said lance may be moved between raised and lowered positions, said lance having a foot valve at the lower end thereof connected to a rod which extends upwardly through said lance for operative connection to an actuator for opening and closing said foot valve, communication being provided, through a port at said foot valve, with a pressure transducer; said method comprising the steps of: lowering said lance through an opening in said container to a position just above the bottom of said container; opening said foot valve to allow flow of liquids through said lance into said container; sensing the pressure at said foot valve through said port therein with said pressure transducer; providing a signal from said pressure transducer, proportional to said pressure at said foot valve; and raising said lance with said power means, when said pressure transducer signal indicates that the pressure at said foot valve exceeds a first predetermined amount, while keeping the lower end of said lance submerged below the surface of said liquid, until said pressure falls below a second and smaller predetermined amount. 11. The method of filing a container with liquid as set forth in claim 10 including the additional steps of: continuing to sense the pressure at said foot valve with said pressure transducer; continuing to raise said lance, in incremental steps, as said container is filled in response to sensing of pressure at said foot valve as it alternately exceeds said first predetermined amount and falls below said second and smaller predetermined amount until said container is filled. 12. The method of filling a container with liquid as set forth in claim 11 in which the weight of the liquid in said container is monitored by weight means, said weight means providing a cut off signal when said container is filled to terminate flow of liquid from said source of liquid and signal said power means to withdraw said lance from said container. 13. The method of filling a container with liquid as set forth in claim 10 in which said rod is tubular, providing therethrough said fluid communication between said foot valve port and said pressure sensor and including the additional step of: providing a source of low pressure gas to said tubular rod to maintain positive pressure within said tubular rod at all times during filling of said containers. 14. The method of filling a container with liquid as set forth in claim 13 in which said low pressure gas is an inert gas. 15. The method of filling a container with liquid as set forth in claim 13 in which said gas is air. 16. The method o f claim 13 in which said low pressure gas is at a pressure of less than 2 psi.
