Suction vehicle for disposing of sludge and fluids

摘要

The invention relates to a suction vehicle for disposing of sludge and fluids, having a sludge tank (1) which, for filling and emptying by an attached vacuum pump (6, 16), can be subjected optionally to subatmospheric pressure or superatmospheric pressure. A mechanical changeover for changing the air flow direction active on the sludge tank is avoided in that provision is made for a vacuum pump (6) which can be operated in both rotary directions, the rotary direction of which is changed over in each case for the purpose of filling and emptying the sludge tank (1). <IMAGE>
