Abstract: The valve for the minimum waste concrete pump, object of the present invention, comprises a valve for the minimum waste concrete pump that comprises a double-piston alternative-type pump valve provided with an inlet conduit (20) and a discharge conduit (30) installed inside the valve container (10) and arranged next to a concrete reception hopper located above the container, allowing to pump concrete and other pasty substances, such as: sludge, mining residues, grout, mortar, dirty water, and similar. The embodiment of the valve generates the minimum of waste retained after the equipment operation, improving the durability and efficiency of use of the pumps, besides reducing the cleaning time, resulting in a great reduction of operational costs, avoiding the unnecessary displacement of the pump equipment to the central. In addition, this new embodiment results in a valve performing a linear translation movement that reduces component wear and minimizes the need for maintenance on the equipment, as its embodiment does not require constant lubrication.

Abstract: In a liquid supply device, the pump unit has a discharge port for discharging a fluid. The connecting portion is connected to the discharge port. The first and second pipe portions and branch off from the connecting portion. The first introduction unit is connected to the first pipe portion and introduces a first liquid into the first flow channel at a flow rate corresponding to a flow rate of the fluid flowing through the first pipe portion. The second introduction unit is connected to the second pipe portion and introduces a second liquid into the first flow channel at a flow rate corresponding to a flow rate of the fluid flowing through the second pipe portion. The stopping portion stops the flow of the fluid in the second pipe portion.

Abstract: A valve guide includes a valve guide body having a valve guide bore along a central axis thereof. In an assembled configuration of a horizontal valve assembly comprising the valve guide, a valve stem passes through the valve guide bore, connecting a valve body to the valve guide. The valve guide further includes first and second skis that each extends radially outward from the valve guide body to a lower wing outer surface, such that the lower wing outer surface is a first radial distance from the valve guide bore central axis; and an upper wing extending radially outward from the valve guide body to an upper wing outer surface. The upper wing outer surface is a second radial distance from the valve guide bore central axis. The first radial distance is greater than an interior radius of a housing bore the horizontal valve assembly is positioned in for use.

Abstract: An aerosol-generating system may include a liquid storage portion configured to hold liquid aerosol-forming substrate, a vaporizer including a heating element with an internal passage at least partially defined by a surface of the heating element, and a micro pump configured to deliver liquid aerosol-forming substrate from the liquid storage portion to the internal passage of the heating element, such that the vaporizer is configured to heat the delivered liquid aerosol-forming substrate at the internal passage to a temperature sufficient to volatilize at least a part of the delivered liquid aerosol-forming substrate. The micro pump may be configured to deliver a particular amount of liquid aerosol-forming substrate to the internal passage based on the micro pump performing an individual pump cycle.
