Abstract
Abstract The invention relates to an arrangment in containers (1) intended to hold materials of a pumpable consistency. The arrangement comprises a reversible motor (9) which is drivably connected to a rotatable agitator (12) located in the container (1). The arrangement is characterized in that there is arranged between the agitator (12) and the pump (2) a coupling means (11) adapted to couple the agitator to the pump when the agitator is driven in a frist rotational direction, and to hold the agitator disengaged from the pump when the agitator is driven in a second rotational direction, opposite to the first.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
An arrangement for containers (1) intended to hold a pumpable material, such as mortar or a filler, comprising a pump (2) for pumping material from said container; a reversible motor (9); a rotatable agitator (12) drivably connected to the reversible motor (9); and coupling means (11; 17,18) arranged between the pump (2) and the agitator (12), characterized in that the coupling means is adapted to couple the agitator (12) to the pump (2) when the agitator (12) is driven by the motor (9) in a first direction of rotation, and to hold the agitator (12) disengaged from the pump (2) when the agitator (12) is driven by the motor (9) in a second rotational direction opposite to said first rotational direction.
Claim 2
Dependent Claim
121 words
An arrangement for containers (1) intended to hold a pumpable material, such as mortar or a filler, comprising a pump (2) for pumping material from said container; a reversible motor (9); a rotatable agitator (12) drivably connected to the reversible motor (9); and coupling means (11; 17,18) arranged between the pump (2) and the agitator (12), characterized in that the coupling means is adapted to couple the agitator (12) to the pump (2) when the agitator (12) is driven by the motor (9) in a first direction of rotation, and to hold the agitator (12) disengaged from the pump (2) when the agitator (12) is driven by the motor (9) in a second rotational direction opposite to said first rotational direction.
Claim 3
Dependent Claim
17 words
An arrangement according to Claim 1, characterized in that the coupling means (11) is a free-wheel coupling.
Claim 4
Dependent Claim
41 words
An arrangement according to Claim 1, characterized in that the coupling means comprises a first coupling element (17) firmly mounted on the agitator (12) and a second, movable coupling element (18) mounted on the drive shaft (19) of the pump (2).
Claim 5
Dependent Claim
27 words
An arrangement according to Claim 3, characterized in that the movable coupling element (18) is arranged to be moved by means of an electromagnetic control means (16).
Claim 6
Dependent Claim
58 words
An arrangement according to Claim 4, characterized in that the electromagnetic control means (16) is adapted to move the movable coupling element (18) out of engagement with the first coupling element (17) after a given period of time has lapsed from the time of reversing the motor for rotation in said second direction opposite to said first direction.
