摘要： A double-acting jack having a working chamber is fitted with an adjustable stop against which its piston comes to rest. The stop is constituted by a nonrotatable nut, which is axially displaceable by an axially nondisplaceable lead screw with which it meshes. The stop includes means for controlling the supply of pressurized fluid from a supply line to the working chamber, the supply line being opened whenever the piston and its associated rod are not in the end-of-stroke position and closed whenever the piston and its rod are in the end-of-stroke position. The lead screw is mounted to have a slight amount of axial play. The supply line terminates in an annular opening provided on a shoulder of the lead screw, which defines a valve, or in it seat.

摘要： A carburetor has a vacuum operated diaphragm type choke control device that acts in connection with a thermostatic control to permit the carburetor choke valve to be closed during starting but provides a controlled gradual opening of the choke valve after starting. An adjustable stop member permits adjustment of the opening by limiting the extent of movement of the diaphragm. The device includes purge feature for continual self-cleaning of the device. A one-way check valve device and precision by-pass means give exact control of the choke opening.

摘要： The invention relates to a hydraulic steering apparatus comprising a continuously operating pump, an operating motor for controlling the parts to be steered, a control device which is adjustable by the steering wheel and which, in its neutral position, connects the pump to a tank through a short-circuiting path. The control device has two operating positions in which the pump is connected to one side or the other of the operating motor and connects the other side of the operating motor to the tank. The control device has a control element connected to a steering wheel and a following element connected to a metering motor and these elements are relatively displaceable to a limited extent. Apparatus is provided to prevent the steering parts moved by the operating motor from stroking mechanical abutments. The end position of the travel of the operating motor is associated with a limit switch device and a short circuiting path between the primary side of the control device and the tank is established by a switching valve which is a part of the limit switch device.

摘要： The disclosure illustrates a tool which permits the adjustment of a pressure responsive flow controlling diaphragm assembly while the diaphragm is pressurized. The tool is used to adjust the position of a central shaft threaded through the diaphragm and held in place by a locking jam nut. The central shaft and locking nut are received in a center bolt having a hexagonal head which holds the diaphragm assembly together. The tool comprises a base that is mounted over the pressurized face of the diaphragm in place of its normal cover. A series of concentric sockets extend through the base for engaging the center bolt and the lock nut. A center shaft extends through the sockets and has a section of an allen wrench received in a corresponding recess of the central shaft of the diaphragm assembly. Suitable passages in the base enable the diaphragm to be pressurized to a desired adjustment pressure. Manipulation of the various sockets and center shaft permits the central diaphragm shaft to be adjusted upon actual operating conditions.

摘要： A structure for stopping a high energy piston, operating within a cylinder, in a short distance at the end of its stroke. There is provided an annulus of resilient material secured to said cylinder and extending slopingly into the path of said piston. As the piston nears the bottom of its stroke, the interference between the piston and annulus, which gradually increases by virtue of said sloping arrangement, brings the piston to a stop in a short distance.

摘要： This disclosure relates to a pneumatically operated actuator having two cup-shaped housing members snap fitted together at the open ends thereof and sealingly holding an outer periphery of a flexible diaphragm between flange means of the housing members, each flange means having an outwardly directed rib offset relative to the rib of the other flange means and respectively compressing into the outer periphery of the flexible diaphragm. The diaphragm cooperates with one of the wall means to define a chamber therebetween, the one housing member having a passage means interconnecting the exterior of the housing means to the chamber with the passage means including a projection extending into the chamber from the wall means. A plate is carried by the diaphragm and is movable therewith, the plate having an inwardly directed projection means for abutting against the projection means of the one housing member and having means cooperating therewith the maintain fluid communication between the passage means and the chamber.

摘要： A PISTON AND CYLINDER DEVICE HAS AN ADJUSTABLE STOP ARRANGEMENT FOR LIMITING THE STROKE OF THE PISTON. THIS ADJUSTABLE STOP ARRANGEMENT COMPRISES A CASING AND A PLURALITY OF STOP ELEMENTS LOCATED IN SAID CASING IN ALIGNMENT WITH EACH OTHER AND WITH A PISTON-ROD-LIKE MEMBER ASSOCIATED WITH THE PISTON. THE STOP ELEMENTS ARE REMOVABLE FROM THE CASING AND HAVE TWO POSITIONS THEREIN ONE OF WHICH THEY EMBRACE SAID PISTON-ROD-LIKE MEMBER SO AS NOT TO OBSTRUCT MOVEMENT OF IT AND OF THE PISTON AND IN THE OTHER OF WHICH THEY OBSTRUCT MOVEMENT OF THE PISTONROD-LIKE MEMBER. BY RE-ARRANGING THE STOP ELEMENTS IN THE CASING THE PERMITTED STROKE OF THE PISTON CAN BE INCREASED OR DECREASED AS REQUIRED.
