A hydraulic jack has an air compressor connected to an air valve with a port in the hydraulic fluid reservoir. Setting the air valve to a lift-state routes compressed air into the hydraulic fluid reservoir which in turn drives hydraulic fluid to the lift cylinder, rapidly pushing the jack ram up to the vehicle or item to be lifted.
A double action hydraulic jack has a primary hydraulic pump in fluidic communication with the hydraulic fluid reservoir and with the lift cylinder. The hydraulic jack has an auxiliary hydraulic pump also in fluidic communication with the hydraulic fluid reservoir and the lift cylinder. The auxiliary hydraulic pump operates at light-load conditions to drive the jack ram upwards at a rate at least three times faster than at heavy lift-load conditions with only the primary hydraulic pump in operation.
A pneumatic tire seater for seating a tubeless tire on a rim has an advanced rapid air release (RAR) valve mounted on a tank suitable for containing pressurized air. A nozzle is mounted on one end of the RAR valve, and the other end of the valve is in unconstrained pneumatic communication with the interior of the air tank. A piston is within a cylinder of the RAR valve. A control chamber behind the piston contains a compression spring. Control gas passageways provide constrained pneumatic communication between the control chamber and the air tank, passing control gas into the control chamber. In response to actuating a control mechanism, the air in the control chamber is vented out into the atmosphere causing the RAR valve to rapidly open, producing a blast of air of sufficient magnitude to seat a tire on a rim.

A lifting device with a head cavity in the lifting member shaped to accept a removable lifting head. The head cavity in the lifting device—e.g., the piston of a bottle jack—may be provided with threads, or may have the threads removed. A yoke fitted on the lifting head provides registration, horizontal restraint, or both against a lifted object, component, or surface to prevent sliding off the lifting head while in use. In a smooth-walled-shaft embodiment, a set of risers (spacers, adjusters, trims, or shims) serves to adjust an extension height of the shaft, elevating the lifting head with respect to the piston prior to beginning to lift the hydraulic piston.
A pneumatically operated gas valve mounted on a vessel containing pressurized gas. The gas valve includes a piston positioned in a cylinder with one closed end so that the piston seats against a gas outlet to close the gas valve.

Upon filling vessel, some of the pressurized gas enters the control reservoir to provide a control pressure behind the piston. Actuating the control mechanism vents the control reservoir, resulting in the gas valve opening rapidly to release the pressurized gas in the vessel through an exhaust port of the gas valve.

A pneumatic tire seater configured to seat a tubeless tire on a rim has a manual internal slip (MIS) valve mounted on the end of a tank. A nozzle is mounted on one end of the MIS valve, and the other end extends partially into the air tank. The MIS valve has a slotted chamber with slotted chamber holes, and a slip cylinder that fits within the slotted chamber and has slip cylinder holes. A compression spring in the MIS valve exerts force on the slotted cylinder, pushing it forward to line up the cylinder holes with the slotted chamber holes and release the high pressure air from within the tank which goes through the MIS valve and out the nozzle.

A tool for seating a tubeless tire on a rim using pressurized gas includes a cylindrical pressure tank with a nozzle affixed to it, and a rapid opening gas valve. The nozzle includes a jet configured to receive pressurized gas from the cylindrical pressure vessel into a chamber of the nozzle. As the stream of gas enters the chamber, the Venturi effect causes air to enter the chamber through air intake ports and the stream of gas and air from the air intake ports is blown out of the outlet of the nozzle. The tire is seated on the rim by positioning the system so that the air from the nozzle rapidly blows into the tire between the bead of the tire and the rim upon the valve being opened.

An air gun with a quick-release pneumatically operated gas valve that includes a piston positioned in a cylinder with one closed end so that the piston may seat against a gas outlet to close the gas valve. A control reservoir filled with gas to a control pressure is formed in the cylinder between the piston and the closed end of the cylinder so that the control pressure acts against the piston to close the gas valve. Opening a trigger valve allows the gas in the control reservoir to escape through an exhaust port, resulting in the gas valve being rapidly opened.

A tool for seating a tubeless tire on a rim using pressurized gas includes a cylindrical pressure vessel with a pistol grip extending radially from the tank. The tool includes a rapid opening gas valve positioned between the cylindrical pressure vessel and a nozzle. In some embodiments the nozzle includes a jet configured to receive pressurized gas from the cylindrical pressure vessel into a chamber of the nozzle so that as the stream of gas enters the chamber, the Venturi effect causes air to enter the chamber through air intake ports and the stream of gas and air from the air intake ports is blown out of the outlet of the nozzle. The tire is seated on the rim by positioning the system so that the air from the nozzle rapidly blows into the tire between the bead of the tire and the rim upon the valve being opened.
Various embodiments of a tool for seating a tubeless tire on a rim using pressurized gas may include combinations of a cylindrical pressure vessel with a grip extending radially from the tank, a pneumatically controlled, rapid opening gas valve, and a nozzle utilizing the Venturi effect. A tire is seated on a rim by positioning the tool so that the air from the nozzle rapidly blows into the tire between the bead of the tire and the rim upon the valve being opened.
A nozzle for seating a tubeless tire on a rim using pressurized gas includes an outlet, a jet configured to accept pressurized gas and emit a stream of gas through an orifice into a chamber.
