Abstract: A shut-off valve housing having a through-channel extending inside a main body between an inlet opening and an outlet opening, and a valve seat disposed inside the through-channel. To reduce flow losses, an outflow region of the through-channel immediately downstream of the valve seat on an outflow side has an inwardly curved contour.

Abstract: An installation is provided in a cargo area of a vehicle for the stowage of a vehicle jack and tools useful in the changing of a wheel of the vehicle. The installation includes a receptacle in a recess in a deck of the cargo area. The receptacle includes an open top container having space to accommodate the jack and the tools. A cover plate across the top of the container covers a portion of the top only, leaving an access opening through which the jack and the tools may be inserted into and removed from the space in the receptacle.

Abstract: A lightweight acid-resistant plastic dispenser having a handle housing enclosing a valve and valve-operating mechanism and remote therefrom on a rigid tubular extension a plastic water nozzle and a flexible hose connected to a water source.The nozzle of the dispenser has two ducts, one for water and the other for aspirated air to produce a suction when the level of the liquid in the battery cell being filled reaches the lower end of the nozzle. The aspirated or suction air operates a diaphragm to break a toggle in the valve-operating mechanism, automatically shutting the water valve in the handle housing.The valve control mechanism in the handle comprises a double toggle composed of three alignable links which when aligned operate against the normally spring-pressed water valve to hold it open.
