The invention describes a hydraulic device for inflating inflatable objects, formed by a folding container that has a folding half and a rigid half, an inserted threaded neck; a perforated cap and internally threaded closes the perforation of the neck; a first conduit is connected into the perforation of the inserted neck; a check valve is provided at the other end of the first conduit, such valve is compose of a body that has inside 3 ducts; a second conduit for filling with air the inflatable object, is connected to a check valve, by means of one of its ends; an inflating valve is attached to the other end of the second conduit; and a liquid is housed inside the holding container.

Also describes machines, modules, devices, etc., which comprise said hydraulic device.

Inflation kit, especially for inflating balloons, balls and the like, characterized in that it comprises: two opposing hollow interlocking bodies, one having at least one inlet for air coming from the outside and the other body having at least one outlet for air coming from the internal cavity defined by the two bodies; an extractable bellows inside the internal cavity defined by the two bodies, through which air can flow from the air inlet to the air outlet; a valve that can be coupled to the air outlet of one of the bodies; and lastly a deflated inflatable element housed inside the cavity defined by the two bodies.

This invention relates to a base with inflation mechanism for deflated ball vending machines made up of an external pedal connected to two pneumatic pistons joined at the top thereof to a pressure gauge, from which there extends a hose connected to a T-connection, which in the bottom part thereof includes a washer to which there are attached two springs adhered to the internal walls of the vending machine, which allow the hose with the valve located on the outside of the machine to inject the air into the ball. The T-connection, in turn, is joined to another hose that has at the end thereof a relief valve covered on the outside of the machine by a cam that releases the air flow injected into the ball.

To provide a toy ball which includes an air plug which facilitates the injection and discharge of air and which does not have to be plugged immediately after the completion of air injection, a toy ball is made up of a ball main body which has an air hole in a predetermined position and which is formed into a spherical body by injecting air into an interior thereof and a hollow rod-like air plug which is freely detachably mounted in the air hole in the ball main body and which allows air to be injected therethrough while kept mounted in the air hole, and the air plug is made up of a pipe-like air injecting pipe having an enlarged portion at an outer end portion thereof, an air flow-in member which is mounted at an inner end portion of the air injecting pipe and which has a space in an interior thereof, and a valve which is inserted in the space in the air flow-in member in such a manner as to be movable to a distal end of the air injecting pipe so as to be secured thereto.

Bei einer Vorrichtung zum Verbessern des Spielverhaltens von Hohlraumbällen, bei der der Innendruck eines Balles (3) dadurch korrigiert wird, daß in den Ball (3) eine Kanüle (15) im wesentlichen aufwärts gerichtet eindringt, durch die Gas (17) und Dichtungsmittel (18, 19) eingeführt werden kann, soll das Betriebs­verhalten verbessert werden. Auch soll eine noch zuverlässi­gere Abdichtung der behandelten Bälle erreicht werden. Zu diesem Zweck ist vorgesehen, daß in Strömungsrichtung dicht vor der im wesentlichen aufwärts gerichteten Kanüle (15) eine Sperreinrichtung (40) zur manuellen oder selbsttätigen Sperrung des Rückflusses von Dichtungsmittel angeordnet ist.
