The valve can receives the coil spring, which can be supported by the oil filter housing, to force the valve can into contact with the oil filter media with a constant pressure. | 10-09-2014 |
| 20140318643 | ACTUATOR FOR A WATER SPRAY STRUCTURE - An actuator system for a fluid playground including a first elongated tubular member defining a first axially extending enclosure and having a first inlet connectable to a fluid source, and a second elongated tubular member positioned within the first tubular member, the second tubular member defining a second axially extending enclosure, and having a second inlet in fluid communication with the first enclosure and an outlet traversing the first tubular member. The outlet is connectable to at least one fluid playground device. A plug element is shaped to removably and sealably close the second inlet of the second tubular member. A resilient member urges the plug element towards sealing engagement with the second tubular member. A pressure exerted on a movable actuating element connected to the plug element causes its displacement away from sealing engagement with the second inlet, thereby allowing fluid flow to the fluid playground device. | 10-30-2014 |
| 20150027568 | AIR PURGING PRESSURE REGULATING VALVE - A valve housing receives a spool and the spool has a regulating chamber selectively communicating a supply line to a return line. The spool is biased in one direction by a spring force and there is a second force biasing the spool in an opposed direction with the second bias force being provided by a fluid pressure within a hydraulic system associated with the pressure regulating valve. The amount of communication between the supply port and the return port is regulated by a position of the spool as the bias force from the fluid pressure change. Damper chambers are provided on opposed sides of the spool and serve to dampen a speed of movement of the spool and a supply line for supplying fluid into the damper chambers through check valves. The supply line serves to assist in purging air outwardly of the damper chambers. | 01-29-2015 |
| 20150059882 | Assembly - An assembly includes: a first component; a second component enclosed by the first component; a diaphragm that covers a radial gap between the first and second components and is fixed in each case in a sealed manner; and a volume of a medium that is enclosed by the first and second components and the diaphragm. For the purpose of achieving a simple filling process of the assembly with the medium at a reliable sealing of the enclosed volume, even in the case of high, swelling pressures acting upon the assembly, in one of the components a filling valve is situated that opens towards the volume, which filling valve is situated as a check valve having spring resetting in a filling channel running in the component. | 03-05-2015 |

| 20150346732 | ADJUSTABLE PASSIVE FLOW REGULATOR - An adjustable passive flow regulator may be used in the field of drug delivery (liquid or gaseous, e.g. for pain management) or for draining cerebrospinal fluid (CSF) for hydrocephalus patient. | 12-03-2015 |
| 20160018013 | CHECK VALVE ELEMENT AND CHECK VALVE USING THE SAME - Provided is a check valve element enabling efficient supply of fluid while suppressing the occurrence of chattering. The check valve element is provided to be displaceable upstream and downstream in a downstream flow path extending downstream from a valve seat having an opening for introducing a fluid and is pressed against the valve seat by a pre-closing urging force applied thereto toward an upstream side. The check valve element has an arresting portion provided on an outer peripheral surface thereof, a sliding resistance imparting member support portion supporting a sliding resistance imparting member such that the sliding resistance imparting member slides along the wall of the downstream flow path when the check valve element is displaced upstream and downstream, and an urging member support portion supporting an urging member urged upstream so that the urging member urges the sliding resistance imparting member upstream, thereby causing the sliding resistance imparting member to increase in outer diameter while being arrested by the arresting portion. | 01-21-2016 |
| 20160025238 | TWO-STAGE SWITCH VALVE - A two-stage switch valve includes a valve body slidable in a flow passage of a fluid, and a spring urging the valve body upstream. The valve body includes a valve element slidable in the flow passage, an upstream guide having a ring shape and being slidable in the flow passage, and legs connecting the valve element and the upstream guide. The upstream guide is located upstream of the valve element. The legs are inclined from an axial direction of the upstream guide and extend from the upstream guide toward a center of the valve element. | 01-28-2016 |
| 20160138726 | PRESSURE REDUCTION VALVE AND GAS SUPPLY DEVICE - The pressure reduction valve includes: a cylindrical portion, a piston and a spring. The cylindrical portion includes an inlet communicating with the primary side flow path and an outlet communicating with the secondary side flow path. The piston fitted into the cylindrical portion is slidable along an axis direction of the cylindrical portion within the cylindrical portion, and defines, within the cylindrical portion, a space communicating with the inlet and the outlet. The spring applies, to the piston, a force acting toward the space. The outlet is displaced in one direction from the center of the piston when seen in the axis direction. The force applied to the piston by the spring is distributed so as to deviate from the center of the piston to the side of the outlet. | 05-19-2016 |
