| 7434710 | Bellows pump mechanism A bellows-type pump includes a body portion with an inlet and an outlet. A bellows member is secured to the body portion and provides a dosage volume that communicates with both the inlet and outlet. Compressing the bellows member causes a sealing web thereof to con... | 10/14/2008 |
| 6782800 | Diamond-shaped fluid powered linkage, system and engine A fluid powered linkage (12) has at least three side plates (18) of substantially equal width joined by connectors (17) to form a polygon of variable cross sectional area. An upper plate and a lower plate enclose a variable volume within the pol... | 08/31/2004 |
| 6637314 | Actuator An air is evacuated from a chamber of a bellows by a vacuum pressure supply source connected to a vacuum port of an attachment plate. The vacuum pressure in a vacuum chamber is thus balanced with the vacuum pressure in the chamber of the bellows. Conseque... | 10/28/2003 |
| 5700135 | Bellows cam plate pump A cam plate pump comprises a pressurizing chamber formed by a bellows which elongates and contracts along a center axis parallel to the input shaft of the pump. The cam plate rotates together with the input shaft, and compresses the bellows via a piston. ... | 12/23/1997 |
| 5033270 | Rotary bellows An actuator, which directly converts fluid pressure to rotary movement, has generally cylindrical and helically fluted circumferential wall, an end wall bearing an output member, and a fixed opposite end wall. The actuator may be a one-shot device providi... | 07/23/1991 |
| 4833973 | Pressure actuated assembly extendable by fluid pressure and retractable by spring action A fluid pressure actuated assembly includes a casing made of a flexible resilient material, such as rubber or polyurethane, a coiled tension spring sleeved on the casing for biasing the casing to move toward a retracted position, and a coiled spacing spri... | 05/30/1989 |
| 4533067 | Fluid medium storage and expulsion apparatus An apparatus (10) for the storage therewithin and expulsion therefrom of a fluid medium includes a tubular tank (15) and a pair of diametrically opposed, simultaneously actuatable pistons (50) permanently sealed to the tank by a pair of rupturable seals (... | 08/06/1985 |
| 4377966 | Servo boosters for vehicle braking systems In a servo booster for a vehicle braking system, of the kind having a tie rod for relieving the booster housing of braking reaction forces which extends through the movable wall(s) of the booster, the movable wall is sealingly connected to a wall of the h... | 03/29/1983 |
| 4268042 | Flexible bellows piston seal Means and method are provided for utilizing a piston and cylinder combination eliminating the usual sealing and oil rings and their accompanying friction and replacing them with ball bearings which in the principal embodiment are captured in splitring cag... | 05/19/1981 |
| 4109465 | Wind energy accumulator A device is proposed which accumulates and stores energy of blowing wind. Rotatable means turn the device into the direction of the blowing wind, so that articulated flaps are fully exposed to the wind. These flaps are connected with air pumping means which de... | 08/29/1978 |
| 3999449 | Turbine engine compressor discharge pressure modulated transmission A gas turbine engine and automatic transmission power train having a modulator valve controlled by an engine compressor pressure and altitude responsive force actuator and a speed governor to provide a modulator pressure increasing with increasing engine ... | 12/28/1976 |
| 3941035 | Control unit and method A control unit which is particularly useful in controlling the output pressure of a turbocharger in response to the manifold pressure with compensation for pressure drop at the throttle characterized by a reference unit disposed in the housing for the man... | 03/02/1976 |
