Abstract: A controller assembly for delivering pressurized fluid to a compression treatment device includes a first pump assembly including a first pump unit and a first electrical contact. The first pump assembly defines a first pneumatic passage configured for fluid communication with the pump unit. A second pump assembly includes a second pump unit and a second electrical contact. The second pump assembly defines a second pneumatic passage fluidly communicable with the second pump unit. The first pump assembly defines a receptacle into which the second pump assembly is slidingly receivable. The sliding reception of the second pump assembly into the first pump assembly establishes fluid communication between the first and second pneumatic passages and establishes electrical communication between the first and second electrical contacts.

Abstract: The pump comprises a pump body, a control member, an elastic member, and blades. The pump body has a holding space, one or more pump inlets, and one or more pump outlets. The holding space, the pump inlets, and the pump outlets communicate with each other. The pump outlets communicate with a fuel outlet of the fuel storage device; while the pump inlets communicate with a fuel reservoir of the fuel storage device. The control member passes through the fuel storage device and is rotatably set in the holding space. The elastic member is set fixed on the pump body and connects with the control member. The blades are set in the holding space and connect with the control member. Thereby, no extra energy is needed for the pump to transport the fuel from the fuel reservoir to the fuel cell.

Abstract: A sprayer system for reducing the need to manually create pressure within a portable spray unit. The inventive device includes a reservoir, a manual pump, an electric motor, a battery electrically connected to the electric motor, an air compressor mechanically connected to the electric motor, a valve stem within the reservoir, and a safety valve within the reservoir. The valve stem can be utilized by a user to connect a conventional air tank thereto for inserting high amounts of air pressure directly into the reservoir without requiring the use of the manual pump or electric pump. If a power switch is closed, the electric motor will operate the air compressor whenever the air pressure within the reservoir drops below a predetermined level. When the air pressure within the reservoir rises above a predetermined level, the electric motor is deactivated thereby preventing the reservoir from becoming over-pressurized. The manual pump may be utilized when the electric pump fails or the battery becomes discharged.

Abstract: A separating pot for glandless electrical or magnetic drive assemblies includes a pot jacket having a generally tubular body with two ends and a flange portion at one of the two ends, the pot jacket being composed of fiber reinforced plastic with the fiber being wound in alternating layers of circumferential windings and helical windings, and with the flange portion being composed of additional circumferential windings; a bottom member disposed within and closing off the other of the two ends of the pot jacket, the end of the pot jacket being an open end, the bottom member having a generally cup-shaped portion which includes a rim portion surrounding an interior bottom face, the rim portion facing the open end of the pot jacket and extending in an axial direction away from the interior bottom face, the bottom member being in a press fit with the pot jacket and being glued to the pot jacket, the rim portion having a generally conically-shaped interior surface which is enlarged in a direction away from the inte

Abstract: The present specification discloses a brake actuation system for a vehicle, which is applicable to both hydraulically or pneumatically operated/spring released brakes and spring operated/hydraulically or pneumatically released brakes. With such brakes it is often necessary to have secondary means for brake operation or release. Such braking systems thus have primary and secondary means for brake operation or release. The present invention provides a fail-safe system which can provide at least an indication of impending failure. The brake actuation system of the present invention comprises a cylinder within which two axially aligned pistons are axially slidable, the space between one end of the cylinder and one piston being connected to a primary power system and the space between said pistons being connected to a secondary power system.

Abstract: An actuator control system is disclosed using fluid dispensing means to selectively add or remove fluid from a closed actuator system, whereby the movement of the actuator is volume rather than pressure responsive.

Abstract: In a system for opening and closing a main line valve by use of high pressure hydraulic fluid which is controlled from a remote location and in which the fluid passes through a hand pump located at the site of the valve, a protective lock-out system is provided for guarding against personal injury in the event the high pressure fluid should arrive at the hand pump while it is being manually operated. The lock-out system includes a small piston located in an air passageway which is positioned outwardly of the hand pump main piston chamber. This passageway extends from the top of the hand pump main piston chamber toward the IN port which receives the high pressure hydraulic fluid. The piston is connected by a shaft to a poppet valve. The high pressure fluid is applied to the under-surface of the piston and to the seat side of the poppet valve.

Abstract: A fluid pump having manually operable and power operable sections 10a, 10b mounted within a unitary pump body 12 that defines at least one suction and one discharge port 14, 16. The manually operated section comprises a body section 12a defining a bore 20a that slidably supports a piston 24 for reciprocating motion that includes a piston rod 24a that extends outside of the body section and is operatively connected to an actuatable arm 60 pivotally atttached to the pump body. Flow passages 34, 42 including a check valve 32 communicate the suction port 14 with one portion 20a of the piston bore; another flow passage 49 communicates a discharge side 20b of the piston bore with the discharge port. The power operable pump section comprises another pump body section 12b that defines a pair of axially aligned bores 82 that slidably support pistons 80 and an eccentric 84 including a drive shaft 130 rotatably mounted within the pump body disposed intermediate and operatively engageable with the pistons.
