Abstract
The equipment guides a free-flowing material such as mortar or concrete or a liquid, to a lower position, partic. to below a fluid level. It has a guide passage with flexible wall enclosing a chamber in which pressure is generated, acting on the passage. The guide passage is formed by a rigid through section (10), whose opposite sides are joined to each other by the flexible wall (9), the latter running for almost the entire length of the trough. The chamber is enclosed by a further wall (4), opposite the trough section. The flexible wall can be of sheet material, fitted between the trough edges and a cowl covering the trough, and sealed to the cowl at the lower end.
