A gas spring comprises a cylindrical casing, in which a piston rod is guided for displacement concentric of a central longitudinal axis. A damping piston is mounted on the piston rod, dividing the interior of the casing into two sectional casing chambers. A filling of compressed gas is provided inside the casing. A damping device is provided for velocity-dependent damping of a motion of stroke of the damping piston and another damping device is provided for path-dependent damping of a motion of stroke of the damping piston. The result is a gas spring of excellently controllable stroke behaviour.

An elastic connection is established between housing parts of a power-driven machine tool by an elastic connecting element which is attached in form-locking fashion to at least one of the housing parts to be connected, in such a way that the connecting element has a land penetrating a breach of the housing part, and this land connects covering parts of the connecting element that are located in coincidence with the breach.

The invention discloses a unidirectionally-rotating damper. The unidirectionally-rotating damper comprises a housing, a rubber insert part, a rotary plastic part, a unidirectional bearing, a rotary shaft, a gland and a gear, wherein the housing is a barrel body with a closed bottom end; the axially-rotating rotary plastic part is arranged in the housing; the unidirectional bearing is arranged at the centre of the rotary plastic part in a coating manner; one end of the rotary shaft penetrates through the centre of the unidirectional bearing and is in transmission connection with the centre of the unidirectional bearing; the other end of the rotary shaft penetrates through the gland and is in transmission connection with the centre of the gear; the rubber insert part is arranged between the rotary plastic part and the housing; an inclined groove arranged slantwise is arranged in the rubber insert part; and a convex bar matched with the inclined groove is arranged on the surface of the corresponding rotary plastic part, so that a contact surface contacting with the rotary plastic part, of the rubber insert part, is an inclined surface. The unidirectionally-rotating damper disclosed by the invention has the advantages of being resistant to collision and obvious in damping effect; the condition of failure in a high-temperature and low-temperature test is avoided; a downward resistance is generated during rotation due to a spiral structure, and according to the principle of acceleration, the higher rotation speed and force are, the higher damping is; and the unidirectionally-rotating damper is more exquisite and smaller in size compared with external products, and the damping effect is reinforced.

In a control circuit for at least one actuator, in particular for a capacitive actuator of an injection system of an internal combustion engine, a control current can be applied to the actuator.The control circuit has an inductor, e.g., having a core and having multiple windings, the windings being designed and connected to the control circuit such that a control current flowing into the actuator and a control current flowing out of the actuator each flow through different windings of the inductor, and a magnetic flux induced in the inductor or its core by the control current flowing into the actuator and a magnetic flux induced in the inductor or its core by the control current flowing out of the actuator mutually compensate one another.

A robust engine assembly having reduced weight and efficient cooling, without an increase in fuel consumption or carbon dioxide emissions, is provided. The engine assembly includes a double-wall cylinder liner clamped between a cylinder head and a crankcase. A manifold is disposed along a portion of the cylinder liner and includes fluid ports aligned with fluid ports of the cylinder liner to convey cooling fluid to a cooling chamber located between the walls of the cylinder liner. For example, the manifold can be a low-loss hydraulic manifold cast integral with the crankcase. Tie rods connect the cylinder head to the crankcase to clamp the cylinder liner in position. Alternatively, the tie rods can be connected to a main bearing cradle located beneath the crankcase. No attachment features extend into the walls of the cylinder liner, which is especially advantageous when the cylinder liner is formed of aluminum.

The invention discloses a preparation method of a compound type light-weight high-intensity nickel-titanium memorial alloy base high damping material. In the method, a powder sintering method is mainly used as a foundation and a pressureless infiltration technology is used as assistance; a pore-creating technology is firstly adopted; and a unit metal powder cascade sintering method is used for preparing a porous nickel-titanium alloy the holes of which are uniformly distributed; and then the pressureless infiltration technology is adopted for inducing the pure magnesium or magnesium alloy phase with high intrinsic damping, low density and micron scale into the porous nickel-titanium alloy, thereby preparing the high-damping magnesium(or magnesium alloy) / nickel-titanium memorial alloy basecompound material the damping control phase of which is magnesium or the magnesium alloy. The compound nickel-titanium memorial alloy prepared by the invention still has the shape memory effect and the superelasticity action as well as has weight lighter than that of the compact nickel-titanium memorial alloy and intensity and damping capacity more excellent than that of the common porous nickel-titanium memorial alloy. The preparation method has good technical suitability, simple preparation process and low cost, and can be used for manufacturing the light-weight high-intensity compound damping materials, damping structures and apparatuses.
