When the transmission part is located at a first position, the limiting part abuts against the first stop part; when the transmission part rotates to a second position, the limiting part abuts against the second stop part. First and second valve plates are sealed from each other, so that the seal performance of a product can be improved. | 2019-10-10 |
20190309863 | DUCKBILL VALVE ASSEMBLIES AND APPARATUS AND METHODS INCLUDING SAME - A duckbill valve assembly includes a duckbill valve and a spring member. The duckbill valve has a longitudinal axis, a lateral axis transverse to the longitudinal axis, and opposed proximal and distal ends spaced apart along the longitudinal axis. The duckbill valve defines a valve direction extending from the proximal end to the distal end. The duckbill valve includes a first port at the proximal end, and first and second opposed sidewalls. The first and second sidewalls taper inwardly toward one another in the valve direction to form a duckbill structure. The duckbill structure includes a slit proximate the distal end. The duckbill valve is transitionable from a closed position, wherein the slit is closed, and an open position, wherein the first and second sidewalls are laterally separated proximate the slit to form a second port. The spring member includes a spring leg disposed laterally adjacent the first side wall. The spring leg exerts a spring load on the first sidewall, the spring load forcing the first and second sidewalls together to maintain the slit in the closed position. The duckbill valve assembly is configured such that, when the first and second sidewalls are displaced laterally outward to open the slit, the spring leg is displaced in the valve direction and in a laterally outward direction. | 2019-10-10 |
20190309864 | VALVE UNIT FOR A VALVE OF AN INFLATABLE BODY - A valve unit for a valve of an inflatable body, in particular a bladder for a sports ball, is provided. The valve unit comprises a cavity containing a viscous, non-solid material, the cavity being adapted to be repeatedly penetrated by a gas injector, wherein the viscous, non-solid material is adapted to seal the valve unit against gas leakage when the gas injector is not penetrating the cavity. | 2019-10-10 |
20190309865 | Positive Pressure Relief Valve - Disclosed herein is a positive pressure relief valve having a valve assembly, a trigger mechanism, an inlet manual override knob, and an outlet manual override knob. The valve assembly may comprises a valve throat and a main piston positioned at least partially within the valve throat, the main piston configured to selectively open and close the valve throat as a function of a pressure at the inlet to the valve assembly. The valve assembly may comprise a set of throat inserts within the valve throat. The trigger mechanism serves to quickly pressurize the main piston's diaphragm. The trigger mechanism may be positioned in a trigger mechanism housing at the outlet end of the valve assembly. The inlet and outlet manual override knob may be coupled to the main piston and configured to pull or push the main piston, thereby displacing the main piston to open the valve assembly. | 2019-10-10 |
20190309866 | LOW FLOW-RESTRICTION shut-off VALVE WITH EXCESS FLOW CLOSURE FUNCTIONALITY - A valve including a control assembly that is configured to control fluid flow through the valve, The control assembly includes a driving element and a valve member. The driving element is rotatable about an axis between a first operating state in which the driving element maintains contact between the valve member and a valve seat and a second operating state in which the driving element does not maintain contact between the valve member and the valve seat. The valve member is rotatable about the axis independent of the driving element when the driving element is in the second operating state. | 2019-10-10 |
20190309867 | HYDRAULIC SWITCH - The present invention relates to a hydraulic switch arrangement and a fluid switch for incorporating into a hydraulic switch arrangement that may be included in a hydraulic circuit for inhibiting flow of hydraulic fluid through a hydraulic circuit in the event of movement of an apparatus or platform from a stable to an unstable condition. Such platforms or apparatus may include for example, cranes, excavators, teletrucks and forklift trucks and roll over incidents of such machinery is common leading to numerous fatalities. Aspects of the present invention ensure fast switching in the event of a transfer from a stable to an unstable condition. | 2019-10-10 |
