摘要： A novel combustion chamber valve and fuel system for driven fastener hand tool is disclosed having a fuel pump disposed parallel to the combustion and piston chambers. Pressure applied a safety at the nose of the tool is activates the fuel pump in a common direction. Pressure applied on a trigger activates the valve system prior to firing in a common direction. The valve system employs a central shaft coupling three valves, an inlet valve using a novel wedged circumferential edge seal, a control valve using a novel edge circumferential seal with a ventilated support, and a charging exhaust valve using a face seal.

摘要： A hydraulic system may include a reservoir of hydraulic fluid, a hydraulic pump, a directional control valve, a hydraulic work loop, a bypass valve, and a hydraulic motor, as well as a plurality of hydraulic conduits interconnecting such components. When excessive hydraulic backpressures are encountered, the system may employ one or more bypass valves and one or more bypass conduits to automatically, and in an on-demand manner, return some or all of the hydraulic fluid from the hydraulic motor to the hydraulic reservoir without the hydraulic fluid passing through flow constrictions causing the excessive hydraulic backpressures.

摘要： A servo brake cylinder for a distributed brake system with an electric motor, a ball screw assembly with a lead screw and a nut, a piston, a cylinder body is disclosed. The electric motor is connected to the ball screw assembly. The piston is installed in the hollow inner space of the cylinder body, slidable axially. The piston has a hole at the center formed by three sections of surfaces including a first cone surface, a cylindrical surface a second cone surface. One end of the lead screw is connected with the nut, and the other end at the tip of the lead screw has three sections of surfaces including a gradually constricting cone surface from the tip followed by a cylindrical surface, further followed by a gradually expanding cone surface. These surface sections at the lead screw and the three sections of the surfaces at the hole of the piston form an inlet valve and an outlet valve between the piston and the lead screw.

摘要： A system and method that includes a device that is used in a particular method to install bearings into a lift cylinder yoke bore. The device includes use of a hollow bore hydraulic push cylinder that maneuvers a push plate along a threaded rod. The push plate sinks or sets into the bearing and applies pressure through the movement of the hydraulic push cylinder to place the bearing into a fit position without the abrasion that is usually associated with the installation of bearings into the lift cylinder yoke bore. The threaded rod attaches to a threaded bushing that is inserted into the bore and secured with the use of a pin. The threaded rod extends out of the bore opening and allows for the attachment of a bearing, push plate, hydraulic push cylinder, washer and nut.
