Parker Hannifin | Date: 2017-03-29

A valve (10) for a refrigeration system has a valve body (12) with an inlet port (14), an outlet port (16), and walls forming a main cavity (22). A cartridge (20) is configured to reside within the main cavity (22) and has a cylinder in which a piston (30) is movable in a first direction to permit fluid flow from the inlet port to the outlet port and in a second direction to impede fluid flow from the inlet port to the outlet port. A port plate (18) is removably mounted to the valve body for closing an end opening of the main cavity through which the cartridge can be inserted into and removed from the main cavity, and has a plurality of functional ports (26a, 26b, 26c). Each of the functional ports is configured to accept at least one of plural valve control elements (28) for controlling the piston to permit or impede the fluid flow from the inlet port to the outlet port, and is disposed at an acute angle relative to a central axis of the piston, so that a functional component mounted to a respective functional port will not block access to fasteners securing the port plate to the valve body so that the port plate can be removed from the valve body without removal of the control element(s) from the port plate.

A quick connect/disconnect coupling having a female coupler (10) and a corresponding male coupler(80). The female coupler has a non-spill configuration and includes a housing (12) and a valve body (14) slidably movable in the housing. A valve member (16) is slidably movable in the valve body toward and away from a valve seat(38), the valve member being configured to engage the male coupler. A piston (18) is interposed between a main cavity and a trap chamber (30) of the female coupler. The piston may be fixed to the valve member for common movement, and may include an internal flow passage (22) for enabling fluid connection between the main cavity and trap chamber. A check valve (74) may allow fluid flow from the trap chamber to the main cavity when the trap chamber pressure is greater than the main cavity pressure. A locking collar (50) may be independently movable of the valve body to reduce the force required to connect the couplers.

A self-aligning, self-drawing coupler for coupling body assemblies together improves usability of a wearable robotic device. A self-contained removable actuator cassette improves the ease of manufacture and of replacing parts in the field. A tensioning retention system designed for one handed operation makes donning and doffing a wearable robotic device easier. A two-stage attachment system increases the range of sizes a wearable robotic device will fit. A removable, integrated ankle-foot orthotic system makes donning and doffing a wearable robotic device easier. An infinitely adjustable, integrated ankle-foot orthotic system increases the range of sizes a wearable robotic device will fit. A manually-removable hip-wing attachment system makes field changes easier, and protecting such a system from inadvertent disengagement during operation increases safety.

A seal with a wedging element for adjustably compressing the seal. The seal abuts a surface, such as a gate of a gate valve, to seal against the surface with a sealing force that prevents fluid flow therebetween. The sealing force of the seal may be increasing or decreasing compression by adjusting the wedging mechanism. For example, as the seal wears away due to friction between the seal and a sliding gate, the compression may be increased in the wedging mechanism to increase the sealing force to a low threshold.

A servo valve including a piezo-electric actuator, a flexible linkage, and control valves. The piezo-electric actuator is actuatable along a piezo stack axis. The flexible linkage is coupled to the piezo-electric actuator at opposite axial ends of the actuator. Control valves are disposed at laterally opposite sides of the piezo stack axis and include respective valve stems coupled to the flexible linkage. The flexible linkage may be configured to transfer motion of the piezo-electric actuator along the piezo stack axis to a motion of the valve stems along an amplification axis that is transverse to the piezo stack axis to open and close the control valves. A symmetric actuation element incorporating the piezo-electric actuator, or a different actuator, may have first and second chambers at laterally opposite sides thereof, and be electrically actuatable along an actuation axis to open and close supply and return ports to control fluid communication with respective first and second work ports of respective first and second chambers.

Exemplary control valves that may be configured as a load sense, closed-center, and/or open-center valve. The control valve may include optional individual valve force sensing to potentially allow an operator to smoothly operate devices operating on low-load work ports even when a variable displacement pump is inducing pressure to operate a device connected to a high-load work port of a separate valve or worksection in the same stack. This optional force sensing may be employed on any or all worksections associated with any valve stack, and may further be included on one or both workports for any given worksection. Each worksection may include parallel and variable paths of fluid supplied by the pump. Also, flow priority to one or more worksections or external valves in a corresponding hydraulic system is optional and can be customized using the variable flow path and a corresponding fixed restriction.
