摘要:
Valve controller for reciprocating piston internal combustion engines with at least two intake and/or exhaust gas-exchange valves for each piston/cylinder unit, wherein the gas-exchange valves are guided by valve stems in a cylinder head (8) of the reciprocating piston internal combustion engine, loaded in a closing direction by valve springs, and can be controlled via a common bridge (10) by an activation device, wherein the bridge (10) is guided over a sliding surface parallel to the movement of the gas-exchange valves, the bridge (10) has at least one hydraulic valve clearance compensation element (14 or 15) that connects to a gas-exchange valve, and a device is provided that prevents rotation of the bridge (10) about the sliding surface.

A laser device, including a cradle with a laser unit exiting from this, the cradle being connected to a base element, relative to which the cradle can be adjusted in terms of inclination by at least one actuating drive. In order to achieve a secure mounting of the cradle for the laser unit with simple structural means, while at the same time eliminating any play between the mutually tilting parts, it is proposed that the cradle be connected to the base element, first, by a solid joint, and secondly by two adjusting drives, wherein the adjusting drives are arranged with respect to the solid joint so that the lines of connection between lengthwise axis of the solid joint and the adjusting drives subtend a right angle.

A disposable absorbent article is disclosed having a unitary structure with a waist opening and a pair of leg openings. The unitary structure includes a front region, a back region and a crotch region positioned between the front and back regions. The front and back regions having an interior surface and an exterior surface. A portion of at least one of the front and back regions has tactile properties similar to cloth underwear.
摘要:
An electrohydraulic control module is provided for making available a compressed fluid, especially compressed oil for actuators, which are used for actuating control units, for example, for switching gas-exchange valves of an internal combustion engine on and off, with a control housing, which is attached to a connection part of the internal combustion engine and which has electrical switching valves that are connected to an oil supply line and to control oil lines leading to the actuators. The production and assembly expense of the electrohydraulic control modules is reduced in that an intermediate housing (6), which is injection molded from plastic and which has at least the oil supply line and the control oil lines (17), is clamped between the connection part (5) and the control housing (7).

Tissues having a high level of softness and hand protection in combination with improved cleaning are disclosed. The tissues have been shown to remove more mucus than commercially available tissues.
摘要:
A hydraulic unit (5) is provided for a cylinder head (2) of an internal combustion engine with a hydraulically variable valve train (1). In the hydraulic unit, a high-pressure chamber (11), a medium-pressure chamber (12), and a low-pressure chamber (16) used as the hydraulic medium reservoir are formed. The low-pressure chamber communicates via a throttle point (17, 17′, 17″, 17′″) with the medium-pressure chamber, and the throttle point is formed by a displaceable valve body (19, 19′, 19″, 19′″) and has through-flow cross sections of different sizes according to a position of the valve body.
